Label

Show Label	Show or hide the x-axis label.
With this expression, you can modify the x-axis labels. The field is empty by default. If you do not provide any expression here, the x-axis values will be displayed without modification, that is, as they are defined by the x-value expression or the category group expression.
Expression	For line charts and column charts, you can select an expression differing from the category group expression. However, you should 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.
Format Code	For scatter charts and bubble charts, the x-axis values are always defined by the x-value expression, which typically return a numeric or date/time value. For these chart types, you can only define the Format Code for the numbers (see Format Codes).
