Empty Charts

[Jehanzeb]

Hello All,

 

I am using two types pf charts; Pie Chart and Horizontal Bar Negative Value charts. When the application starts, I want to show empty charts in both of these cases. For example, in case of pie chart, I don't want that the pie chart with default data (the one displayed on design time) is shown. The chart should be drawn when the user select a few options and press the display chart button.

 

Thanks in advance.

Simply call:

chart.Data.Clear();

In your form load.

Hello,

 

Thanks for your prompt reply.

 

The problem is that I am using the chart control in a UserControl. So, can you please tell me whether it's fine to call chart.Data.Clear() in the Load event of the UserControl. I have written the same code in the Initialize method of my UserControl but it's not working.

 

Regards,

It all depends where you are creating your chart.

If you are creating your chart at design-time then the Load event is fine.

Bottom-line is you wan to call this as late as possible before paint, after you have customize everything you want in your chart.
