Hi everybody,
I need to find slopes for multiple lines shown in the attached figure, and then report them in a single table (sheet) without going through them one by one. Any idea?
Thanks in advance ^_^

Dear Chris D,
Thank you for your answer,
This is what I really do.
To be more specific, I need to plot slope vs Temperature. the temperatures are, for example, 300, 302, 304, ... etc. (Please see the attached example) and I copy each slope next to the corresponding temperature manually, which takes a long time. How can I do it faster?

Hi Morad,
Try this:
1. Go to the Analysis menu and choose Fitting->Linear Fit.
In the Input tab of the Linear Fit dialog, click on the arrow button and choose "Add all plots in active layer:. Then for Multi-Data fit Mode, choose "Independent Fit - Consolidated Report".
Does this do what you want?
Thanks,

Or use the simple fit gadget and generate output for all curves from the same layer. |

Thank you for your answer,
In my case, it doesn't matter if it is linear or not. I usually do the linear fitting and look for the relative slope. Nevertheless, My problem that when I do fitting, I go to the results and copy & paste them one by one to a new worksheet.
In other words, assume the data is linear (as attached), and I did a linear fitting for the group, How can I get the results in a new worksheet without copy & paste the results manually? is there a coding way to do that?
Thanks and best regards,

Well, since they're only partially straight, you might need to first chk the derivatives to find the straight range and perform fitting on it.
It is automatable, but some scripting would be needed more or less. |
