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.
Yes, of course.
The configuration is expressive, and the result slick. No doubt !
But I haven’t found a way to plot the time series expressed in % of it value as of the left bound of the selected interval.
Let me rephrase.
Imagine I have 2 stocks (say AAPL as in your example, and also MSFT), and I want to see which one performed better over the interval selected by the slider.
How do I do that ? How do I compare them visually ?
This is what highcharts/highstocks enables you to do very easily (cf the link in my previous post).
I think a similar example should be posted - if it’s possible with plotly - is it ?
It’s been 4 years since this post, and I still can’t hardly find a solution. In finance we use terms like normalized or indexed to 100, unfortunately those terms have different meanings in python and pandas. It would seem that I can not be the only one looking for this solution.
