Description

Expected Behavior

Is there an elegant and simple way to visualize a few trading models plotted on 1 chart? In fact a lot of projects like mine are centered around comparing various models (and even groups of models), so that would be handy to have a sugary way around this process, so:

  1. individual models with notations on one chart
  2. a group of models trading on the same account each having a proportional share of the capital

Actual Behavior

works with just 1 model

Contributor guide

Research direction
Explore the current plotting implementation in backtesting.py, specifically how single model plots are generated, and design an extension to overlay multiple model traces. Consider using matplotlib's subplots or multiple axes.
