Hi I've got a chart with several panes with different readings plotted in each pane (i.e. one series on each pane), and AxisSection's added to the XAxis to highlight regions across the panes. Randomly when I hover over a section item in the legend to highlight it on the chart, i get a runtime unhandled exception (below). This happens even if there is just one pane. Hovering over the sections in the chart doesn't cause the problem, only in the legend. Any ideas?

Chart.Series.Clear(); Is what I was looking for...

Hi, I have a situation where I bind data to chart, rebind different data to it, then rebind the original (after certain events). When rebinding the original data again, the Y Axis isn't the same as what it was when binding originally. In between this rebinding I'm calling: Chart.Data.Clear();Chart.Panes.Clear();Chart.Points.Clear();Chart.DataSourceSettings.Fields.Clear(); And I'm calling Chart.AxisY.ResetScale() and have AutoScale to true. What else should I call? Chart.Reset() works but it clears all of the formatting properties set earlier also. I've also tried Chart.AxesY.Clear(). Any ideas? Mark
