Error adjusting AxisY in multiple panes


Recommended Posts


I have a chart with multiple panes whithin. Each pane represents the historic evolution of stock value. All works fine except in one case.

If I generate a chart with three or more panes (stocks values) and two of those have the max a min value overlapped, the graph throws error. The error trace is this:

The binding values have this maxs and mins:

Serie #1 :  1196 - 1056
