Package: visdom_plotly
# **Notice**This package is based on [Visdom](https://github.com/facebookresearch/visdom). It just has an additional method [Visdom.plotly()](https://github.com/rahmatkhah/visdom/blob/master/py/__init__.py#L1219) that directly supports plot.ly, see the [demo_plotly.py](https://github.com/rahmatkhah/visdom/blob/master/example/demo_plotly.py) example.Requires Python 3.6 and plot.ly```bash# Install Python server and clientpip install visdom_plotly```# **Visdom**![visdom_big](https://lh3.googleusercontent.com/-bqH9UXCw-BE/WL2UsdrrbAI/AAAAAAAAnYc/emrxwCmnrW4_CLTyyUttB0SYRJ-i4CCiQCLcB/s0/Screen+Shot+2017-03-06+at+10.51.02+AM.png"visdom_big")A flexible tool for creating, organizing, and sharing visualizations of live, rich data.

These appear in windows that you can drag, drop, resize, and destroy. The windows live in `envs` and the state of `envs` is stored across sessions. You can download the content of windows -- including your plots in `svg`.> **Tip**: You can use the zoom of your browser to adjust the scale of the UI.#### Environments<p align="center"><img align="center" src="https://lh3.googleusercontent.com/-1wRSpNIoFeo/WLXacodRTMI/AAAAAAAAnEo/sTr5jSnQviA0uLqFIvwPGledmxcpupdkgCLcB/s0/Screen+Shot+2017-02-28+at+2.54.13+PM.png" width="300" /></p>You can partition your visualization space with `envs`. By default, every user will have an env called `main`. New envs can be created in the UI or programmatically. The state of envs is chronically saved.You can access a specific env via url: `http://localhost.com:8097/env/main`. If your server is hosted, you can share this url so others can see your visualizations too.>**Managing Envs:**>Your envs are loaded at initialization of the server, by default from `$HOME/.visdom/`. Custom paths can be passed as a cmd-line argument. Envs are removed by deleting the corresponding `.json` file from the env dir.#### StateOnce you've created a few visualizations, state is maintained. The server automatically caches your visualizations -- if you reload the page, your visualizations reappear.<p align="center"><img align="center" src="https://lh3.googleusercontent.com/-ZKeFJfMe5S4/WLXebiNgFwI/AAAAAAAAnFI/AH2cGsf40hEWbH6UeclYQcZPS0YZbcayQCLcB/s0/env_fork_2.gif" width="400" /></p>* **Save:** You can manually do so with the `save` button. This will serialize the env's state (to disk, in JSON), including window positions. You can save an `env` programmatically.<br/>This is helpful for more sophisticated visualizations in which configuration is meaningful, e.g. a data-rich demo, a model training dashboard, or systematic experimentation. This also makes them easy to share and reuse.* **Fork:** If you enter a new env name, saving will create a new env -- effectively **forking** the previous env.#### FilterYou can use the `filter` to dynamically sift through windows present in an env -- just provide a regular expression with which to match titles of window you want to show. This can be helpful in use cases involving an env with many windows e.g. when systematically checking experimental results.<p align="center"><img align="center" src="https://lh3.googleusercontent.com/SJEoacYeHkVer5PEpYlJGOSdFX2gt2_GAVsTpg4k2Wea-RxoJ9e3zW_6xqq2g4WWV-JaIaMOLopAvssYgV2XqshhttRacNgRZQKfrreKOJls1RmwtLsA-SauhPPCKosUveab8dJmv7jQZ40sBLJZUXUXa5daCF16DQn7MtxpctP5Wx2MoOJI56DokT6KUj_Pl3I5M5N_y_kDt6f1pOl1FYjHCzV5no58OXHlyqVapLriX8MbfuZ2CWw6ZFY-XNlv5Cja8R9fKOt1956JVGcqo1u7OVM80eevhT69wUS97fw98UGklPhKwrxCgiGvwu_td__8YALleplfgILOR-_9aNMkNM1pnbZ9isHYGLGpBCOV2PnLdxqDcbjM0ojVzh5DLVBJbV3v2WAlbbCztktd5Kk6O5tWRN3tO4uH-Lm80mWJ-6dWip1Lj4qHWOvlCa0Tg6T_s9GY9zEule32knQdYmY7EmoJKpFFOhZuvX9GXWwz3Pu2nnYIzyaXGAax3qQhbEcPY_4zx20nHY2r5clKPAtyDt3unf7yg0Bk8kJb7bZj8BqdL-eof891vJttbiHXz37Dmpr3Qh1r2-AFr72mtafp-kNmPDjkEaxxRkHpQP03MSN2iGlfDC7OY7bsxmGwE-oJKfi59o6MfJcR3HMiNfsx7ARe0u6mujHj6EIl9n8=w373-h185-no" width="300" /></p>## SetupRequires Python 2.7/3 (and optionally Torch7)```bash# Install Python server and clientpip install visdom# Install Torch clientluarocks install visdom``````bash# Install python from sourcepip install -e .# If the above runs into issues, you can try the beloweasy_install .# Install Torch client from source (from th directory)luarocks make```## UsageStart the server (probably in a  `screen` or `tmux`) :```bashpython -m visdom.server```Visdom now can be accessed by going to `http://localhost:8097` in your browser, or your own host address if specified.>If the above does not work, try using an SSH tunnel to your server by adding the following line to your local  `~/.ssh/config`:```LocalForward 127.0.0.1:8097 127.0.0.1:8097```.#### Python example```pythonimport visdomimport numpy as npvis = visdom.Visdom()vis.text('Hello, world!')vis.image(np.ones((3, 10, 10)))```#### Torch example```luarequire 'image'vis = require 'visdom'()vis:text{text = 'Hello, world!'}vis:image{img = image.fabio()}```Some users have reported issues when connecting Lua clients to the Visdom server.A potential work-around may be to switch off IPv6:```vis = require 'visdom'()vis.ipv6 = false  -- switches off IPv6vis:text{text = 'Hello, world!'}```### Demos```bashpython example/demo.pyth example/demo1.luath example/demo2.lua```## APIFor a quick introduction into the capabilities of `visdom`, have a look at the `example` directory, or read the details below.### BasicsVisdom offers the following basic visualization functions:- [`vis.image`](#visimage)    : image- [`vis.images`](#visimages)   : list of images- [`vis.text`](#vistext)     : arbitrary HTML- [`vis.video`](#visvideo)    : videos- [`vis.svg`](#vissvg)      : SVG object- [`vis.save`](#vissave)     : serialize state server-side### PlottingWe have wrapped several common plot types to make creating basic visualizations easily. These visualizations are powered by [Plotly](https://plot.ly/).The following API is currently supported:- [`vis.scatter`](#visscatter)  : 2D or 3D scatter plots- [`vis.line`](#visline)     : line plots- [`vis.updateTrace`](#visupdatetrace)     : update existing line/scatter plots- [`vis.stem`](#visstem)     : stem plots- [`vis.heatmap`](#visheatmap)  : heatmap plots- [`vis.bar`](#visbar)  : bar graphs- [`vis.histogram`](#vishistogram) : histograms- [`vis.boxplot`](#visboxplot)  : boxplots- [`vis.surf`](#vissurf)     : surface plots- [`vis.contour`](#viscontour)  : contour plots- [`vis.quiver`](#visquiver)   : quiver plots- [`vis.mesh`](#vismesh)     : mesh plots### Generic PlotsNote that the server API adheres to the Plotly convention of `data` and `layout` objects, such that you can produce your own arbitrary `Plotly` visualizations:```pythonimport visdomvis = visdom.Visdom()trace = dict(x=[1, 2, 3], y=[4, 5, 6], mode="markers+lines", type='custom'marker={'color': 'red', 'symbol': 104, 'size': "10"},text=["one", "two", "three"], name='1st Trace')layout = dict(title="First Plot", xaxis={'title': 'x1'}, yaxis={'title': 'x2'})vis._send({'data': [trace], 'layout': layout, 'win': 'mywin'})```### Others- [`vis.close`](#visclose)    : close a window by id- [`vis.win_exists`](#viswin_exists) : check if a window already exists by id- [`vis.check_connection`](#vischeck_connection): check if the server is connected## Details![visdom_big](https://lh3.googleusercontent.com/-bqH9UXCw-BE/WL2UsdrrbAI/AAAAAAAAnYc/emrxwCmnrW4_CLTyyUttB0SYRJ-i4CCiQCLcB/s0/Screen+Shot+2017-03-06+at+10.51.02+AM.png"visdom_big")### Basics#### vis.imageThis function draws an `img`. It takes as input an `CxHxW` tensor `img`that contains the image.The following `opts` are supported:- `opts.jpgquality`: JPG quality (`number` 0-100; default = 100)- `opts.caption`: Caption for the image#### vis.imagesThis function draws a list of `images`. It takes an input `B x C x H x W` tensor or a `list of images` all of the same size. It makes a grid of images of size (B / nrow, nrow).The following arguments and `opts` are supported:- `nrow`: Number of images in a row- `padding`: Padding around the image, equal padding around all 4 sides- `opts.jpgquality`: JPG quality (`number` 0-100; default = 100)- `opts.caption`: Caption for the image#### vis.textThis function prints text in a  box. You can use this to embed arbitrary HTML.It takes as input a `text` string.No specific `opts` are currently supported.#### vis.videoThis function plays a video. It takes as input the filename of the video`videofile` or a `LxHxWxC`-sized`tensor` containing all the frames of the video as input. Thefunction does not support any plot-specific `opts`.The following `opts` are supported:- `opts.fps`: FPS for the video (`integer` > 0; default = 25)Note: Using `tensor` input requires that ffmpeg is installed and working.Your ability to play video may depend on the browser you use: your browser hasto support the Theano codec in an OGG container (Chrome supports this).#### vis.svgThis function draws an SVG object. It takes as input a SVG string `svgstr` orthe name of an SVG file `svgfile`. The function does not support any specific`opts`.#### vis.saveThis function saves the `envs` that are alive on the visdom server. It takes input a list (in python) or table (in lua) of env ids to be saved.### PlottingFurther details on the wrapped plotting functions are given below.The exact inputs into the plotting functions vary, although most of them take as input a tensor `X` than contains the data and an (optional) tensor `Y` that contains optional data variables (such as labels or timestamps). All plotting functions take as input an optional `win` that can be used to plot into a specific window; each plotting function also returns the `win` of the window it plotted in. One can also specify the `env`  to which the visualization should be added.#### vis.scatterThis function draws a 2D or 3D scatter plot. It takes as input an `Nx2` or`Nx3` tensor `X` that specifies the locations of the `N` points in thescatter plot. An optional `N` tensor `Y` containing discrete labels thatrange between `1` and `K` can be specified as well -- the labels will bereflected in the colors of the markers.`update` can be used to efficiently update the data of an existing plot. Use 'append' to append data, 'replace' to use new data. If updating a single trace, use `name` to specify the name of the trace to be updated. Update data that is all NaN is ignored (can be used for masking update).The following `opts` are supported:- `opts.colormap`    : colormap (`string`; default = `'Viridis'`)- `opts.markersymbol`: marker symbol (`string`; default = `'dot'`)- `opts.markersize`  : marker size (`number`; default = `'10'`)- `opts.markercolor` : color per marker. (`torch.*Tensor`; default = `nil`)- `opts.legend`      : `table` containing legend names`opts.markercolor` is a Tensor with Integer values. The tensor can be of size `N` or `N x 3` or `K` or `K x 3`.- Tensor of size `N`: Single intensity value per data point. 0 = black, 255 = red- Tensor of size `N x 3`: Red, Green and Blue intensities per data point. 0,0,0 = black, 255,255,255 = white- Tensor of size `K` and `K x 3`: Instead of having a unique color per data point, the same color is shared for all points of a particular label.#### vis.lineThis function draws a line plot. It takes as input an `N` or `NxM` tensor`Y` that specifies the values of the `M` lines (that connect `N` points)to plot. It also takes an optional `X` tensor that specifies thecorresponding x-axis values; `X` can be an `N` tensor (in which case alllines will share the same x-axis values) or have the same size as `Y`.`update` can be used to efficiently update the data of an existing plot. Use 'append' to append data, 'replace' to use new data. If updating a single trace, use `name` to specify the name of the trace to be updated. Update data that is all NaN is ignored (can be used for masking update).The following `opts` are supported:- `opts.fillarea`    : fill area below line (`boolean`)- `opts.colormap`    : colormap (`string`; default = `'Viridis'`)- `opts.markers`     : show markers (`boolean`; default = `false`)- `opts.markersymbol`: marker symbol (`string`; default = `'dot'`)- `opts.markersize`  : marker size (`number`; default = `'10'`)- `opts.legend`      : `table` containing legend names#### vis.updateTraceThis function allows updating of data for extant line or scatter plots.It is up to the user to specify `name` of an existing trace if they wantto add to it, and a new `name` if they want to add a trace to the plot.By default, if no legend is specified at time of first creation,the `name` is the index of the line in the legend.If no `name` is specified, all traces should be updated.Trace update data that is all `NaN` is ignored;this can be used for masking update.The `append` parameter determines if the update data should be appendedto or replaces existing data.There are no `opts` because they are assumed to be inherited from thespecified plot.*Note: This function will be deprecated in upcoming versions.*#### vis.stemThis function draws a stem plot. It takes as input an `N` or `NxM` tensor`X` that specifies the values of the `N` points in the `M` time series.An optional `N` or `NxM` tensor `Y` containing timestamps can be specifiedas well; if `Y` is an `N` tensor then all `M` time series are assumed tohave the same timestamps.The following `opts` are supported:- `opts.colormap`: colormap (`string`; default = `'Viridis'`)- `opts.legend`  : `table` containing legend names#### vis.heatmapThis function draws a heatmap. It takes as input an `NxM` tensor `X` thatspecifies the value at each location in the heatmap.The following `opts` are supported:- `opts.colormap`   : colormap (`string`; default = `'Viridis'`)- `opts.xmin`       : clip minimum value (`number`; default = `X:min()`)- `opts.xmax`       : clip maximum value (`number`; default = `X:max()`)- `opts.columnnames`: `table` containing x-axis labels- `opts.rownames`   : `table` containing y-axis labels#### vis.barThis function draws a regular, stacked, or grouped bar plot. It takes asinput an `N` or `NxM` tensor `X` that specifies the height of each of thebars. If `X` contains `M` columns, the values corresponding to each roware either stacked or grouped (depending on how `opts.stacked` isset). In addition to `X`, an (optional) `N` tensor `Y` can be specifiedthat contains the corresponding x-axis values.The following plot-specific `opts` are currently supported:- `opts.rownames`: `table` containing x-axis labels- `opts.stacked`    : stack multiple columns in `X`- `opts.legend`     : `table` containing legend labels#### vis.histogramThis function draws a histogram of the specified data. It takes as inputan `N` tensor `X` that specifies the data of which to construct thehistogram.The following plot-specific `opts` are currently supported:- `opts.numbins`: number of bins (`number`; default = 30)#### vis.boxplotThis function draws boxplots of the specified data. It takes as inputan `N` or an `NxM` tensor `X` that specifies the `N` data values of whichto construct the `M` boxplots.The following plot-specific `opts` are currently supported:- `opts.legend`: labels for each of the columns in `X`#### vis.surfThis function draws a surface plot.

Two optional `NxM`tensors `gridX` and `gridY` can be provided that specify the offsets ofthe arrows; by default, the arrows will be done on a regular grid.The following `opts` are supported:- `opts.normalize`:  length of longest arrows (`number`)- `opts.arrowheads`: show arrow heads (`boolean`; default = `true`)#### vis.meshThis function draws a mesh plot from a set of vertices defined in an`Nx2` or `Nx3` matrix `X`, and polygons defined in an optional `Mx2` or`Mx3` matrix `Y`.The following `opts` are supported:- `opts.color`: color (`string`)- `opts.opacity`: opacity of polygons (`number` between 0 and 1)### Customizing plotsThe plotting functions take an optional `opts` table as input that can be used to change (generic or plot-specific) properties of the plots. All input arguments are specified in a single table; the input arguments are matches based on the keys they have in the input table.The following `opts` are generic in the sense that they are the same for all visualizations (except `plot.image` and `plot.text`):- `opts.title`       : figure title- `opts.width`       : figure width- `opts.height`      : figure height- `opts.showlegend`  : show legend (`true` or `false`)- `opts.xtype`       : type of x-axis (`'linear'` or `'log'`)- `opts.xlabel`      : label of x-axis- `opts.xtick`       : show ticks on x-axis (`boolean`)- `opts.xtickmin`    : first tick on x-axis (`number`)- `opts.xtickmax`    : last tick on x-axis (`number`)- `opts.xtickvals`   : locations of ticks on x-axis (`table` of `number`s)- `opts.xticklabels` : ticks labels on x-axis (`table` of `string`s)- `opts.xtickstep`   : distances between ticks on x-axis (`number`)- `opts.ytype`       : type of y-axis (`'linear'` or `'log'`)- `opts.ylabel`      : label of y-axis- `opts.ytick`       : show ticks on y-axis (`boolean`)- `opts.ytickmin`    : first tick on y-axis (`number`)- `opts.ytickmax`    : last tick on y-axis (`number`)- `opts.ytickvals`   : locations of ticks on y-axis (`table` of `number`s)- `opts.yticklabels` : ticks labels on y-axis (`table` of `string`s)- `opts.ytickstep`   : distances between ticks on y-axis (`number`)- `opts.marginleft`  : left margin (in pixels)- `opts.marginright` : right margin (in pixels)- `opts.margintop`   : top margin (in pixels)- `opts.marginbottom`: bottom margin (in pixels)The other options are visualization-specific, and are described in thedocumentation of the functions.### Others#### vis.closeThis function closes a specific window. It takes input window id `win` and environment id `eid`. Use `win` as `None` to close all windows in an environment.#### vis.win_existsThis function returns a bool indicating whether or not a window `win` exists on the server already. Returns None if something went wrong.Optional arguments:- `env`: Environment to search for the window in. Default is `None`.#### vis.check_connectionThis function returns a bool indicating whether or not the server is connected.## To Do- [ ] Command line tool for easy systematic plotting from live logs.- [ ] Filtering through windows with regex by title (or meta field)- [ ] Compiling react by python server at runtime## ContributingSee guidelines for contributing [here.](./CONTRIBUTING.md)## AcknowledgmentsVisdom was inspired by tools like [display](https://github.com/szym/display) and relies on [Plotly](https://plot.ly/) as a plotting front-end.
