Hi together,

one problem with linear fit:

I would like to fit some temperature data over 15 years. In case of the summertemperature it is no problem. For winter temperature it shows the values but no line in the diagram. I've checked all options, many videos but there is no solution for this problem. Thank you very much!

Best regards
ST.

Hello James,

thank you for your help! I've created a zip file with two bmp files to explain it a little bit more detailed. Can you give me a short note if it works?

Best regards

Sorry, it is still hard to tell what the issue is. Would you mind sharing the project file as well? Thank you.

Hi James,

i've prepared another one zip. There are three screens, one with used data, one with summer temperature diagram and one with winter temperature diagram. The Line plot for winter isn't working. Thanks a lot.

For some reason, the graph is messed up, the x scale range is 0.5-13.5. Somehow the x values are treated as text, but it is properly set as numeric in worksheet. Do you remember what changes you made on the graph?

Can you just remake the graph with col(F) and Col(G) and run the fitting, it should be fine.
