Hi Cho,
You need to turn off automatic labels and provide custom ones - for example:

   NOrdinalScaleConfigurator scaleX = nChartControl1.Charts[0].Axis(StandardAxis.PrimaryX).ScaleConfigurator as NOrdinalScaleConfigurator;
    scaleX.AutoLabels = false;
    scaleX.Labels.Add("One");
    scaleX.Labels.Add("Two");

Please take a look at the All Examples \ Axes examples that show how to configure different types of axes as well as how to control labels, ticks etc. Let us know if you meet any problems.

I want to customize the scale label on the chart.

First, I want to know how to hide the scale label.

Second, I want to replace the label with a string.
For example, if the X axis value is 1, replace it with the string "One" and if it is 2, replace it with the string "Two".

please answer about my question.
Thank you.
