Make the token balance graph show total balance instead of one for upload/download

Tribler version/branch+revision:

Tribler 7.1.2

I've been using Tribler for some time, and find that i very easily go in the negatives, likely as a result of torrents that are highly available, but not in demand, at least on Tribler net. (Upload almost exclusively remain at 0 for these torrents) As a result, the upload and download lines will split significantly, and make it practically useless to try to monitor recent changes in upload.
By moving over to a total balance in the graph, that gradual changes would be much more apparent, at least when do actively downloading.
The drawback would be, that though, you can't realistically observe upload when downloading with the proposed method, but in it's current state, it's not all that much better.

An alternative, if possible, is to do the total way, and color a vertical line under the balancegraph as "download" for the given interval, and another for upload, if that is a feasible option. See quick mockup:

Imagine the top shaded area could be colored blue for given, and another shaded area under showing the taken amount. (Samle code for graph can be shared)

As minor point, not worth an issue, moving to smaller circle orbs instead of large ones for each "record" in the graph, would also likely increase readability, as the large points overshadow the finer changes of the lines in the current implementation. Or as in the above image, not use points at all, depeding on what you prefer.

@Thomasedv Thank you for the suggestion and I appreciate your effort in creating the graph mockup. I agree that monitoring the changes in the recent uploads when there is a big (negative) difference in the balance is not so useful and showing the differential value could be more informative. However, the differential upload value will still remain small and be less visible when plotted on the same graph with the same scale. We'll discuss it in the team and update the issue.
