You can enable and configure these buttons in the properties of the X axis.
Zoom function
In the pause mode, the <+> button enlarges the center of the X axis and in the live mode the last part of the X axis. The <–> button reduces accordingly. The default value of the zoom factor is 2. This means if the section of the X axis is enlarged, it is half as large as the original section, if it is reduced, the section of the X axis is twice as large as the original section. The zoom factor can be modified via the X axis properties.
For more information, see X-axis.

The step can be set via the X axis properties. The default setting for little steps is relative 0.75 and for large steps relative 2. Alternatively, the step can be set as absolute value in hh:mm:ss time units for time-based values and in meter for length-based values.
Example: if the X axis indicates a range of 100 s and if the time stamp goes to 10:00:00, a small step jumps to the left by 75 s on 09:58:45 and a large step to the left by 200 s on 09:56:40.
For more information, see X-axis.
Panning is possible in paused mode only. When pressing one of the pan buttons in live mode, the display will switch to paused mode automatically.

Jump to a date
Clicking the button 
opens a calendar where you can enter a date and time on second basis.
With a click on the arrow to the right, the display of the trend graph jumps to this time point.
This function is also available on length-based HD trend graphs because the time stamp is always stored along with the length-based data.
A time leap is possible in paused mode only. When pressing the jump button in live mode, the display will switch to paused mode automatically.
