MSCRM 2015: Rename legend in bar chart - reporting-services

Question

I have created a bar chart with two categories and one series as below.
Chart condition
Chart
The requirement is to change the Legend names Open and Disqualified to Ongoing and Cancelled. The Legend names are nothing but the 2nd Category (Status).
I went through the code, but not able to figure it out where to add the Legend names.Kindly suggest some solution if any.
Below is the code I have given for reference.

Answer 1

If you want to change only the chart display then Use the LegendText property inside each series you want to change:
<Series ChartType="Column" LegendText="Ongoing" DrawSideBySide= "False" IsValueShownAsLabel="True" Font="{0}, 9.5px" LabelForeColor="59, 59, 59" CustomProperties="PointWidth=0.75, MaxPixelPointWidth=40">
<Series ChartType="Column" LegendText="Cancelled" IsValueShownAsLabel="True" Font="{0}, 9.5px" LabelForeColor="59, 59, 59" CustomProperties="PointWidth=0.75, MaxPixelPointWidth=40">
Otherwise the statecode optionset can be customized in Lead entity to reflect across the system.
