I am plotting Linear fits of data. I cannot find an option that allows me to get the slope of the linear plot.
Anyhelp here please?
Er, no Labview available.

Thanks again. I see how this button-script relation works now. |

Open Custom.ogs in notepad and replace the script under the [Main] section with your script. That section is run by the Custom Routine button on Origin's standard toolbar.

Thanks a lot Mike. I can now do exactly what I wanted to. Is there any way to turn this into a convenient button? |

The Analysis->Fit Linear and Tools->Linear Fit menu commands print slope and intercept to the results log. Use the stat object to obtain those values programmatically.

That's OK. LabView is not required.
...You can add a text label to your graph showing the slope and intercept as follows.
1. With graph active run Analysis->Fit Linear.
2. Enter this LabTalk command in the script window...
label -s -sa "slope=$(stat.lr.b)\nintercept=$(stat.lr.a)";
That will create a text label that looks like this...
slope=<value of slope>
intercept=<value of intercept>
