如何强制DevExpress图表仅显示可用值的标签？

Question

Let me try to explain the problem:

• We have a DevExpress scattered point chart :

• To which we need to bind the following data:

We need to show the first column provider id as X axis' series label.

Now, if we look at the chart, there're only four places where the X axis' series label is required however, there're multiple X axis' series labels.

We need to show the X axis' series labels only for the points for which we have data on Y axis.

It's understood that the chart is automatically adjusting the X axis' series label as numbers.

How can one force chart to show labels only for available values?

Answer 1

To accomplish this, adjust the Series.ArgumentScaleType property and set it to Qualitative .
