Using ScatterLineSeries and NumericXAxis results in duplicated axis labels
posted

Is this a proper behaviour?

I'm using a ScatterLineSeries with NumericXAxis.

I do not set explicite Intervals for the axis. For most cases it works great, soo my axis labels look like this:

| 1992, | 1993, | 1994, | 1995

(off course I'm using DataTemplate for the axis label).

Now, the issue is that, for small number of "x" values, the labels are duplicated!. So, I have this:

| 1992, | 1992, | 1993, | 1993

In other words, there are more labels than x values.

Is there some property to set in order to get rid of duplicated values?

I've double checked my data structures, and they seems fine.

Off course I could set Interval to 1 and have this issues solved, but the problem is that there can be thousands of values (then, having interval set to 1 makes my axis not really readable).

    Czesc Lukasz,

    You can hide labels with duplicated values by implementing visibility type converter and adding methods to handle chart’s SizeChanged and ActualWindowRectChange events. I created a sample application that hides labels with duplicated values and I also added another NumericXAxis so you can compare custom axis with default behavior of labels rendering.

    Please let me know if you have more questions about this.

    Thank you,

    Martin
