I'm trying to implement this with stock data and I've found the chart isn't accurate. In the example app you provided for example. With the bitcoin prices in the chart it's only calculating for percentage changes. Not actual change in the price. If it went down 10% in one day then the next day it went up 1% it'll show that as a 10% gain. All I want is to be able to add all of the prices and it will display it accurately on a chart. Can you please update your repo to fix this. Thanks
