Accumulated performance over time#94

Make it possible to see how the portfolio performes over time.

There are already nice charts of various information, but seeing the value of the portfolio over time, together with interest vs. added value would be nice.

Other charts could be added as well, seeing how the accumulated performance of the portfolio adds to the SDG’s.

This. There is no place on your page where I can see how much money I earned all together. Only the interests earned, but there are also late payments (need to filter those out under transactions) that i have to add mannually to my repaid interests.
