Chart Labels Misplaced

[Brett]

I would like to limit the number of X-Axis Label Steps to around 3 or 4 labels.  The amount of data displayed on the chart can vary from just 5 points to hundreds and the number of points for each Pen can vary significantly. 

It is my assumption that the “XAxis.LabelStep” property assumes a constant number of points for each ChartSeriesItemCollection.  I had originally set it to

                Chart1.PlotArea.XAxis.LabelStep = Convert.ToInt32(MaxPoints / 3) +1;

But I get a strange group of characters in the upper left portion of the trend and the incorrect number of Labels created.  Given my objective, what would be the ideal way to specify the number of Labels for the X-Axis?

Hello Brett,

We have only seen this problem when you have modified the LabelStep of the YAxis to a value bigger than one. To avoid the problem, set the LabelStep of the YAxis to 1. Instead use the chart1.PlotArea.YAxis.Step to modify the step of the labels. You also need to set the chart1.PlotArea.AutoScale = false (so the Step and MaxValue are taken into account).

If the problem continues, we would appreciate if you open a support ticket and provide us with a sample that exhibits the problem.

About modifying the LabelStep of the XAxis, it is good to set the LabelStep to a number that divides to the item Count. Otherwise the labels won't stick to the major ticks but will be shifted instead.
