Abstract:
1. A method of generating a Java-based chart comprising the steps of: retrieving chart data using a hypertext transfer protocol from a remote world-wide web accessible server system using a Java-based applet program executing within a window of a browser program on a client computing system; wherein said chart data relates to a price history for a company stock; presenting said chart data in graphical form in said window for viewing by a user as a visual historical price chart for said company stock; wherein said visual historical price chart is generated using display data from a window data buffer used by said Java-based applet program; providing a set of user selectable commands within said window for permitting said user to annotate said visual historical price chart directly at said client computing system, including with one or more annotation items; wherein said annotation items include at least one of the following for said visual historical price chart: trend lines and/or descriptive text labels provided by said user; modifying said display data directly at said client computing system in said window data buffer based on said user annotating said historical chart with one or more of said annotation data items to generate modified display data; wherein said user can see both said visual historical price chart as well as such user-supplied annotation items in said window of said browser program using said modified display data.
