Browsing the plotly functionalities advertised for finance I realise that there is a crucial feature missing .
(Note: I don’t want to sound critical - I find the recent improvements of plotly very impressive !)
What is missing ?
(At least I have found no example and not simple way to do it so far)
The ability to plot time series in relative value, with a slider over dates that plots the time series in percentage of their value on the left bound of the period selected by the slider.
See highcharts/highstock: http://www.highcharts.com/stock/demo/compare
I work in finance and I can guarantee that this is the most useful plot we have ever used.
To put is short, finance is all about time series (very often relative) values.
So much that I even wrapped highcharts for use inside a notebook:
Does the plotly team plan to add it to the fast growing capabilities of this interesting lib ?
Or is there already a way ? Some pointers ?
