Figure for relative error with large database

Question

[Evy_00]

I have some data of RNAs in different tissues, and I worked out the relative errors of my data and the data provided by the reference. I want to describe the range of the relative error to know that whether I did the pipeline correctly or not. Could someone give me some advice to do that? Python or R will be better.

Here is the structure of the reference data, there are some scores of each gene in different tissues. My data and the relative error have the same structure. BTW, I have thousands of gene.
