Topic: 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?
Bet Wishes,
SH

Re: Difference between point series and function

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.
