Tag: Custom Legend

Hello,

I am trying to make a legend for a graph with some complex data.

Here is an example of how my data is structured:

• Data Set #1
  • Series A
  • Series B
  • Series C
• Data Set #2
  • Series A
  • Series B
  • Series C
• Data Set #3
  • Series A
  • Series B
  • Series C

By default, SciChartLegend will display 9 entries in the above example, one for every series. However, with many datasets, and more series per dataset, this quickly becomes extremely cumbersome.

What I’d like to do is show 6 items in the legend: a checkbox for each Data Set, and a checkbox for each Series Type.

If the user clicks the Data Set #1 check box => Data Set #1 Series A, Data Set #1 Series B, and Data Set #1 Series C are all shown/hidden.

If the user clicks the Series A check box => Data Set #1 Series A, Data Set #2 Series A, and Data Set #3 Series A are all shown/hidden.

This does not seem to cooperate with the native SciChartLegend, which views all the Data Series as a single flat list. My data is in more of a tree structure.

Do you have any recommendations on how to proceed? I think I will need to make a new UserControl derived from ChartDataObjectBase to replace the SciChartLegend control.

Any help greatly appreciated.

Thank you,

Kurt
