This goes out to all the exchanges, data warehouse, price chart plotters:
PLEASE someone start a movement which will hopefully spread through the whole cryptocoin-scene:
ENABLE y-axis SCALING! PLEASE. It drives me nuts, that so many charts are completely USELESS as soon as someone sells his coins for 1/100 times the current price - probably being stoned out of his head, and simply misinterpreting all those confusing digits.
Then for the following day, or week, or month, there is a spike in the data, which doesn't tell us anything about the currency (only about this one stoned user). And that spike destroys the usefulness of the chart, until it finally wanders off far enough into the past.
Another reason is the burst after a coin enters an exchange. It's suddenly traded for 10 times as much - for a few hours. Then in the following days weeks months, this unrealistic price is still dominating the y-axis range, and the charts are useless.
Similiar for the volume charts.
It is probably real volume, but often ranging over many orders of magnitude, because of a sudden burst in trading. Once I have understood that spike in volume, I want to cut it out, to clearly see all the other data.
A simple three-button (+/-/reset) for the y-axis maximum would be a good starting point
Please please please someone enable us to choose the y-axis range ourselves.
Many sites seem to use the same library for plotting charts, anyways. So if you find a way to extend that library (or to finally use it properly, perhaps the function is long possible, just not enabled?) ... you will help us all.
Thanks.
