The "Offer book" graph is showing inconsistent information

[fedegrc]

Hi, I'm creating this issue in order to propose a change to the graph located in the section "Market -> Offer book". First, I'll describe the issue I'm seeing using this graph:

Following the table related to the Buy side of the previous graph:

The summation of all BTCs is 1.28 BTC. If we want to buy all BTCs, we should spend USD 12047.77, so the Price is 12047.77 / 1.28 = 9412.32. If we see the graph, it shows a Price of ~9760 instead of 9412.32

I have been working on a R function that could solve this issue and provide useful information. The result is this graph:

@fedegrc Thanks for pointing this out. I'll have to see how this is calculcated atm and will come back to this issue soon.

@ripcurlx , an easy way to see that the graph is wrong is recognizing that sometimes there is a vertical lines showing the same Price for two or more Amount in BTC, which is mathematically impossible (except if the vertical line is in the "first/best" value).

The Price col of the following table shows the correct values:

  USD    BTC  cumsum(USD) cumsum(BTC)   Price
 353.12 0.040    353.12     0.0400    8828.0000
1070.73 0.125   1070.73     0.1650    8629.3939
1056.80 0.125   1056.80     0.2900    8553.9655
2119.60 0.250   2119.60     0.5400    8518.9815
1059.80 0.125   1059.80     0.6650    8511.3534
