Re: Legend for AChart control?

Hi there! I am plotting several signals on a chart (2 or more) and I'd like to represent a legend with the signals plotted and their names. Can anyone please help me with some info about how to do this?

Re: Legend for AChart control?

I solved this problem by creating an APanel object next to my chart named 'pnlLegend'.  Then, after the chart's plots were created and populated, I called this procedure.  It loops through the plots in 'cht1' and dynamically creates labels with the color and name of each plot:

ob: Object                     !Temporary object used for creating controls dynamically
lPlotIndex: Long               !For loop counter
lTop: Long                     !Tracks the top of the controls added to the panel
lPlotTitleLeft: Long Const = 35   !The Left value for the plot title label
lPlotColorLeft: Long Const = 10   !The Left value for the plot color label


  for lPlotIndex=0 to cht1.PlotCount-1

    !Insert label to display plot color
    ob=Form.InsertControl("lblPlotColor"+Str(lPlotIndex), "ALabel", lPlotColorLeft, lTop, 10, 10, pnlLegend.Name)

    !Insert label to display plot name
    ob=Form.InsertControl("lblPlotTitle"+Str(lPlotIndex), "ALabel", lPlotTitleLeft, lTop, 50, 10, pnlLegend.Name)
