How can I get the plot area of the chart?

I want to get the size of the plot area. How can I get it in a chart?

 

Thanks

You need to access the left, top, bottom, and right properties of the PlotAreaMargin of the chart. You can do the following:

 To retrieve its values:

int x1 = Chart1.PlotAreaMargin.Left;

int y1 = Chart1.PlotAreaMargin.Top;

int x2 = Chart1.PlotAreaMargin.Right;

int y2 = Chart1.PlotAreaMargin.Bottom;

Then to calculate the height and width, you can do the following:

width = right - left, if right > left

height = bottom - top, if bottom > top

What if all the following variables

int x1 = Chart1.PlotAreaMargin.Left;

int y1 = Chart1.PlotAreaMargin.Top;

int x2 = Chart1.PlotAreaMargin.Right;

int y2 = Chart1.PlotAreaMargin.Bottom;

 

are set to Zero, then how can I find the plot area?

Thanks

If those variables were set to zero, then you wouldn't have a plot area. Note that the plot area is an actual rectangle that is composed of a set of points within the chart control.

Also, you can access the bounding rectangle of the pane (plotted area) and retrieve its left, top, right, and bottom values respectively, as well as the height and width of the rectangle.

You can access this rectangle by calling:

chart1.Panes[0].BoundingRectangle.Height;

chart1.Panes[0].BoundingRectangle.Width;

Thanks a bunch, that helped
