hi

i want to fit a line through my data with the linfit function but my x-
axis is in string format. Is there a way to avoid transforming the
string time array into non-string (e.g. other function which is as
easy as linfit)?

cheers

Not really. At the time I have written that tool for the catalog of the
library I have seen this part as documentation examples.

http://www.fz-juelich.de/icg/icg-1/idl_icglib/idl_source/idl _html/idl_work_libraries.htm

While I am able to extract the examples, I can run them too. But
unfortuantely missed we to define how these examples should look like.
I mean a common syntax how they can be used for automated tests.
(Now I would do it similiar to python.)

One focus of the lib is a plotting environment. For this we use human
image comparison. For all the other functions we have lots of tests but
not for automated testing. I'll look in your framework.
