I know that for this you need to change a few variables. Tell me what?

Hello,

I am unsure what specifically they are doing in the video buy they may be using the BarDistance:

ChartControl.Properties.BarDistance

This would give an effect similar or control the spacing between bars which could include more or less data in the visual area.

I look forward to being of further assistance.

for NT7:
ChartControl.BarSpace = 10; // Distance between bars

Thanks for the help
