How to plot Rodeostat data simultaneously with another device?



  • Hi all,

    I am using Rodeostat to run cyclic voltammetry test on my sample and as the test is running, I have another device (RedPitaya) that reads signal of another form from the sample. I could plot the data from both devices on the same graph but they are not in sync (this can be understood since both devices are running in different time system). Essentially, I want to read data from both devices at the same instant. What I have in mind is to read data from RedPitaya, and then from Rodeostat, store the data and plot them on the same time axis (which I will create on my own). However, I am not sure how to achieve that in the Python code or the firmware.

    Is the possible to solve the above problem with software approach?

    Any help is much appreciated!



  • I think Excel will let you do this. Just plot one of the graphs with its time axis; then add the second graph, with its time axis. Excel will locate the points properly. If you want to get fancy, you could write code in Python, or any other scientific programming language, that interpolates between time points and give you estimated graph points from one graph at the other graph's time points.
