Remove white and unnecessary space from Chart control

发布于 2020-10-24 05:18:02

I have a chart and I've added it to a panel but as you can see in the picture, the chart does not fill the whole panel. it has a lot of white space that I highlighted in red.

How can I remove this space on the left, right and bottom of my chart so that it fills the panel?

I tried docking it and I also changed its margin property to false but these solutions did not work.

My chart is .NET WinForms chart:

You can manually set the ChartArea's ElementPosition like this:

ChartArea CA = chart1.ChartAreas[0];
CA.Position = new ElementPosition(0, 0, 100, 100);

This means: Set it to the Top Left and make it fill the chart to 100%.

The remaining white space is needed for the labels; you can tweak it further still by using numbers less than 0% and/or greater than 100%.

Do note that they are not pixels but percent, so they will always relate to the whole ClientSize of the chart control!

This can of course also be done in the properties window. You can expand the chart even more by changing the InnerPlotPosition, if setting the Position to 100% is not enough.
