Setting the upper x-axis limit

The controls shown above are used to set the upper x-axis limit.

If auto-scale upper x-limit  is toggled, the maximum x-value of any of the curves in the plot will be used as maximum value. The edit window  shows the current value, 24000 Hz in this example, which is the maximum in x-direction since  is toggled. It is possible to type a new value, but remember to validate it by pressing Enter.

The controls  are used for moving the upper limit in either left or right direction.
