If the points are scattered equally, you can use Calc|Table to evaluate the function for the same x-cordinates. Otherwise you will have to use Calc|Evaluate. There is no easy way to subtract the coordinates inside Graph. It is probably easiest to use a spreadsheet for that.]]>Fri, 03 Feb 2017 14:12:39 +0000https://forum.padowan.dk/viewtopic.php?pid=3031#p3031<![CDATA[Difference between point series and function]]>

Dear Ivan, I have plotted a point series and also function y=f(x) which seems to fit the points quite well. Is there a way I can plot the points which are the difference of the two so I can see the deviations between the measurements and the fitting function?
