yAxis.GetBounds returns empty rectangle?

Adam S Carney — Sun, 23 Dec 2007 18:49:42 GMT

Using a ScatterGraph, I would like to draw the axis scales in my own code inside the Paint event handler. I can use xAxis.GetBounds() to retreive the rectangle to draw in for the xAxis but yAxis.GetBounds() always seems to return Rectangle(0,0,0,0). Why?

Thanks,

Adam

Hi Adam,

I haven't been able to reproduce your issue yet. What language are you using? Can you post a small snippet of your code that demonstrates how you are trying to access the yAxis bounds?

Thanks Marty.

I'm using C# and VS2005. I wrote a little demo that paints the rectangles returned by .GetBounds(). It shows that when the axis has Position=AxisPosition.Right, GetBounds returns an empty rectangle. I didn't notice that it was just right-hand axes the first time around.

Not sure that my last post had the attachment.

YAxis contains additional overloads of GetBounds that requires you to specify the YAxisPosition as an argument. By default, GetBounds will return the position of the y-axis as if it were positioned on the left. If you have the YAxis positioned on the right side of the plot area, then you should call yAxis.GetBounds(YAxisPosition.Right).

Thank you sir. That is correct. Using GetBounds() or GetBounds(YAxisPosition.Left) returns an empty rectangle when the axis is positioned on the right. One must call GetBounds(YAxisPosition.Right) when it is desired to obtain the right hand axis rectangle when position is .Right or .LeftRight.
