I’ll quote this directly:
What have you tried? Of the posts which Patrick linked it’s a certainty that none of them specifically accomplish your need, but all of them are readily adoptable with some effort. If you are trying but getting stuck then post what isn’t working here, along with your graph and a data set to use (you can leverage one of the sample models provided with Revit and refer people to that but include what version of the software you are in). If your permissions level is not yet sufficient here or file sizes too large you can use OneDrive, Dropbox, Google drive, ACC, box, or services like WeTransfer.
