Signa Graph at top of wallet, calculates history in a strange way? (pool accounts)

[pir8radio]

Describe the bug
In a pool account the graph shows a constant decrease as shown in the attached image. With the high end showing a value that the account has never actually held.

To Reproduce
Steps to reproduce the behavior:

1. Add any pool address using the "Watch Account" feature.
2. View account

Expected behavior
I would expect to see rises (as blocks are won and signa added to pool account) and then drops as payments are made.. But you will notice there is never a "rise" from mined blocks. Also the calculation for some reason always comes up with a very high signa value on the left side of the graph.. Even though that high amount was never really present in the account. Logic seems to try and reverse calculate from the current balance and transactions, i can't put my finger on it, but something is not right there.

Could you give me the addresses of that accounts? So, I can use them as reference when fixing this issue

the first graph is my own pool: S-S456-G8QD-HZQ7-B66VL
Second one is VLP pool: S-MBCG-4ERH-FVH5-2GTXB
Third one is FoxyPool: S-N5P2-3ETU-7LXK-DTU3X

Comment for me: Need to consider Mining Rewards in balance calculation also. This would also affect Solo Miners.

I looked into this feature...The "problem" atm is, that block rewards are not reflected by transactions, so I need to refactor the chart such that I "inject" the forged blocks and the rewards. I opened an ticket for that (#1716) - this requires a bit more effort.
