User story: We need to migrate Firefly density plot (Heatmap with the data calculated on server side) to multi-trace chart architecture. This includes options and table connections.    This ticket is dealing with the options for heatmap. It will not change the server-side algorithm. Currently I am planning to include the options for number of bins in X and Y direction and add an option for [Plotly color scale|https://plot.ly/javascript/heatmap-and-contour-colorscales/]. (If needed we can also use the discretized color scale as we did before.)    07/05/2017 TG    Per Xiuqin’s request, I am adding current server side implementation details for the binning algorithm, which is supposed to split XY space into rectangles and record how many points are falling into each bin. (xUnit and yUnit below are the dimensions of each bin.)    *Input:*      {noformat}    table,    xColumnOrExpr and yColumnOrExpr – columns or column expressions for x and y    maxPoints – maximum number of bins    xyRatio (default 1, aspect ratio of the plot – if we want bins to be more square-like)    xMin, xMax, yMin, yMax (if NaN, use min or max value of the corresponding column/column expression)    {noformat}    *Output:*      {noformat}  1. “decimated" table with the following columns:          x, y, rowidx, weight, decimateKey    where          x, y – x and Y values of a “representative” point – a random point from the bin          rowidx – row index of the “representative” point in the original table          weight – total number of points in the bin          decimateKey – a string "<xIndex>:<yIndex>”, which identifies the bin  2. decimate key information, which contains xMin, xMax, xUnit, and yUnit              this information allows to calculate center of the bin from x and y values above  {noformat}      *Algorithm:*      {noformat}  1. Calculate min and max of x and y columns OR accept them as parameters.  2. Calculate xUnit and yUnit:      nXbins = (int)sqrt(maxPoints*xyRatio)      nYbins = (int)sqrt(maxPoints/xyRatio)        xUnit = (xMax - xMin)/nXs      yUnit = (yMax - yMin)/nYs;      // increase cell size a bit to include max values into grid      xUnit += xUnit/1000.0/nXs;      yUnit += yUnit/1000.0/nYs;    3. Create a map from bin key (decimateKey) to sample (“representative”) point.      for each row         get x and y values (xval and yval) for this row         if either x or y and NaN or the point is not within limits, continue to the next row         calculate decimateKey:            xIndex = (int)((xval-xMin)/xUnit)            yIndex = (int)((yval-yMin)/yUnit)            decimateKey = xIndex+”:”+yIndex        if decimateKey is already present in the map:            increase the number of represented rows  weight for this bin by one                       randomly decide if the current row should be chosen as a “representative”:               if (Math.random < 1.0/weight):                  make current row representative        else            add current point to the map with weight 1    4. Create an output table from the map created in step 3  {noformat}       The algorithm is implemented in doDecimation method of [QueryUtil.java|https://github.com/Caltech-IPAC/firefly/blob/dev/src/firefly/java/edu/caltech/ipac/firefly/server/util/QueryUtil.java]
