Hello!

Hope somebody can help me!

what I wanna do: I have a couple of curves, where I wanna do some linear curve fitting. The fitting always should happen between the x-values 0,025 and 0,050. How can I tell my script to do a linear curve fitting between those two x-values and then give the result (B)...??

thanks for U're help!

Try this ..
Assuming that you are working on your active plotted dataset %C

StartRange=0.025;
EndRange=0.050;
mks1=xindex(StartRange,%C);
mks2=xindex(EndRange,%C);
doc -uw;

There should now be markers delimiting the range x=0.025 and x=0.050 and your fitting would be restricted to that range..
