X Axis

X Axis configuration is located in the right side in the properties, under section X Axis :

Title

X Axis has a default title generated from the name of the currently displayed data field.

If you wish to customize this title, check the box Custom Title, and write a new title :

Hiding Axis Title

Use the Show Title check box to hide or show the title on the axis.

Color

By default, the Labels and Title colors are based on the Theme.
If you want to set a specific different color, check Override Theme Color and set the desired color :

Grid Lines

Grid lines can be hidden or displayed with Show Grid Lines :

Labels Overflow

When Axis Labels are too long to be displayed, the following behaviors can be configured using Labels Overflow :

Hide

Labels are displayed entirely in their original orientation, but the labels that overlap are hidden :

Rotate

Labels are displayed entirely, but if the labels overlap they are rotated to give more space :

Labels Rotation

The Axis Labels orientation can also be rotated for better readability, by setting Labels Rotation :

It can allow for example to fit more labels when using the “Hide” Overflow Mode :

Or alternately to take less space vertically :

Value Type

Sometimes you want to compare groups of values side by side, and the distance on the X Axis doesn’t matter.
Other times, the distances on the X Axis are meaningful and you want to show how close or far the points are horizontally.

This is what the X Axis Value Type setting is for :

Date / Time

When the data field is of type Date, DateTime or Time, the Date / Time option is available.
The X position of points depends on the time difference in the data.

For example, the following data has missing points between day 3 and day 24 but this is not clearly visible and the progression looks linear :

With Date / Time type, the real trend is visible :

Numeric

When the data field is of type Number, the Numeric option is available.
The X position of points depends on the number difference in the data.

For example, the following data has missing points between X value 3 and X value 24 but this is not clearly visible and the progression looks linear :

With Numeric type, the real trend is visible :

Logarithmic

When the data field is of type Number, the Logarithmic option is available.
The X position of points depends on the number difference in the data.

For example, the following data has missing points between X value 3 and X value 24 but this is not clearly visible and the progression looks random :
