Hi,
Attached screenshot https://www.dropbox.com/s/v91drpprqu9il0g/Axis_Scaling_Issue.jpg for reference.
Some of the plotted points are going down the axis, since some points y value is negative.
But Auto scaling is not showing them properly.
How can i set the scale to automatically detect negative values and scale y axis accordingly ??
Its difficult to determine from your screenshot what might be the issue. Is there a way you can provide a sample that replicates the problem?
Please note that if you are using string values for your y data, that although it appears to work, in many ways, the chart will be subtly broken due to the implicit conversions and implicit comparisons going on.
For performance reasons it will not force the incoming values to be numeric values unless you tell it to do so. Please see this post for more detail:
