How do you find(tell, separate, group) the difference between these two graphs(datas) or calculate and grouping these two graphs?

I want to find a way to tell these two cases data as shown in the pictures without comparing to each other.
One is typically reducing from highest to lowest; another is at some range; there are modified.
Thank you.

Thank you for your comment.
I think it's not clear enough too.
This graph plots from singular values taken from SVD calculation.
First graph is normal plot. Second graph plot from modified singular values. So there is two type, original and modified.
In my work, in some process I will get many singular value datas (both original and modified) and I want to separate these datas into two groups.
Sorry if my English is not clear. Thank you for your help.

You can start with combining multiple plots in the same graph for a better visual analysis.
x = rand(1,10); y = rand(1,10);
hold on; %retain current plot and add new plot
Furthermore, you can move forward with bivariate analysis, finding correlation between both the variables or even as simple as finding differences between the values of these variables (euclidean/manhattan distance). This step will depend on the problem you are trying to solve.
