I keep getting an exception error on my chart that happens after the application runs for several hours. The error says 'Axis Object - The minimum value of the axis is greater than the largest data point value'. The YaxisMin and Yaxismax properties are set to auto.

This seems like it may be a bug in the Microsoft Chart control because there have been some discussions around the internet about it. Also see this thread to see if there is anything there to help:

Thanks. I'll try using 'suppressexceptions'. Also I just caught the chart going from 0-35(y) to -600 to 200 just before the error. It's for sure something in the 'estimate' method. I also changed from 'auto' yaxismin and yaxismax to 0 and 50. I'll post the results. I'm sure I'm not the only one seeing this. thanks.

I just want to follow up on this for others that may have the same problem. After changing the yaxismin and yaxismax to real values instead of 'auto' I haven't seen the problem. It was occurring every few hours and it's been ok for nearly 2 days now.

Thanks for the follow up. I had this same problem on a project I was working on last week. I didn't make the connection, but as soon as I added user selection option for setting the mix and max to fixed values, I did not see the problem any more.
