Created attachment 116126 [details] screenshot of the problem - create a new table with 2 columns - fill the table columns with row numbers - create a new custom fit - use as fit function this one a*x - set fit and evaluation interval x:10 - 25 - set start parameter a to '2' - calculate the fit the x-axis runs from 0 - 100 (see also bug 400748). I want to change the x-axis to run from 10 - 25, therefore - click in the plot diagram on the x-axis and set there '10' as start and '25' as end value result: the x-axis does no longer use the full width of the diagram, see the attached screenshot.
Still in 2.6.0RC2.
This is expected behavior. An axis can be shorter than the shown plot range. You have to change the x range of the plot to get the expected result.
