Multiple models on one chart

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
