Extracting data points from subplots (2024)

Thanks! I actually tried this method from here and I found a cell of 3 Lines, but it turns out that trying to extract XData or really any data from these lines overloads the memory of the computer. I think I'm just going to have to redo the tests.

For anybody wondering how to do it with data on subplots, you have to save each line from the cell in dataObjs (from the above link) to a separate variable. Mine just happened to be too big for my computer.

Cheers!

My pleasure!

The original in that post refers to getting data from figures in R2014a and previous versions.

Walter Roberson’s Comment refers to getting data from figures in R2014b and later versions. (This is similar to my solution.)

The differences are significant, and what works for R2014a and previous versions (using HG1) will not work in R2014b and later versions (using HG2).

You must have collected a significant amount of data. Your sampling frequency has to be twice the highest frequency component of interest in the signal you’re sampling. More is ‘oversampling’, and while useful isn’t necessary.

i have the same problem.. my c1.fig file has 11 subplots.. i want to extract data from each subplot as each of them represents a different dataset. i was using f= open (‘c1.fig’); h = findobj (f,’type’,’line’); y1 = get (h(1),’Ydata’); y2 = get (h(2),’Ydata’); y3 = get (h(3),’Ydata’); y4 = get (h(4),’Ydata’); y5 = get (h(5),’Ydata’); y6 = get (h(6),’Ydata’); y7 = get (h(7),’Ydata’); y8 = get (h(8),’Ydata’); y9 = get (h(9),’Ydata’); y10 = get (h(10),’Ydata’); y11 = get (h(11),’Ydata’); then i was plotting.. but matlab is just extracting data from the last subplot and putting it in all subplots… what should i do.. any idea would be grateful

Thanks
