Hi Fabio,

Do you specify a View to the chart axis? Can you send us the code that you use to configure the chart for review?

Thanks for the response. That doesn't seem to be solving the issue. As additional information I will add that if I zoom a little it works correctly. 

Zoomed a little image: 

Hi Fabio,

This is most likely caused by the default line join - the following code shows how to change the line join of line segments:

line.BorderStyle.LineJoin = System.Drawing.Drawing2D.LineJoin.MiterClipped;

or

line.BorderStyle.LineJoin = System.Drawing.Drawing2D.LineJoin.Round;

Hope this helps - let us know if you have any questions.

Lines with negative values are outside of the chart as seen in this image:



I was wondering if there was a property so that the lines fit inside the charting area. Thanks in advance.
