Dear Origin Team, I am currently stumped and need some assistance.
I am trying to integrate a signal from the lowest point of the plot to an arbitrary distant point. 
So for instance take a look at the 100ns (red) plot. I want to find a way to calculate the minimum value for the large dip right around 200ns x value. I want to then use that corresponding x value and integrate all the way to 1200 (basically the rest of the signal). I want to do this process for all the different lines (100-600ns). The problem is that I dont know how to accurately:
a) calculate that minimum point
b) define the range for the integration.
I have an idea of doing the same integration, but for a maximum to the left of the dip. This way I wouldnt lose some of the signal.
Also, with regards to b: I realize that I can manually drag/define the limits with the cursor, but I would prefer to simply input the "min" value into the range.
Thanks for any help/support you can give me. |

Hi,
Please take a look at this example:
https://www.originlab.com/doc/LabTalk/examples/Peaks-and-Baseline#Integrate_Active_Curve_in_Graph_over_a_Specific_X_Range
To get the minimum value, use the Min function:
