In the Category Properties, select the Label page.
If you want to completely hide the x-axis labels, clear the Show X-Axis Labels check box.
The usage of the expression for x-axis labels depends on the type of diagram:
For line charts and column charts:
If you want to use different labels than the ones resulting from the category group expression, click and enter the required expression in the Expression Editor.
Use an expression that is based on an identifier equivalent to the identifier of the category group expression. For example, if the category is grouped on the sample ID, you could display the sample name. Displaying the sequence name or the injection order number would lead to ambiguous x-axis labels.
For scatter charts and bubble charts:
If you want to use a different format for the numbers defined by the x-value expression, click to enter the required Format Code (see Format Codes).
Save the settings.
