There is a great example of htmlwidgets in the
Interactive Parallel Coordinates.
You can interactively manipulate the Parallel Coordinates Plot to zoom in
on interesting observations.
Sometime ago, I was reading about Visualizing system parameter optimization
results at Visualizing Data.
The article was using XDat app to create
and manipulate back-test results.The idea is to run multiple
back tests by varying system parameters, and display results using Parallel Coordinates
A great example of system parameter optimization is described at
How to optimize trading system.
The article presents a 3 dimensional plot with one parameter on X axis,
one parameter on Y axis, and CAGR on the Z axis. This is a very good approach
if you only optimize two parameters, but what to do if you have more than two parameters?
The Parallel Coordinates come to the rescue. Let’s say we run a
system parameter optimization, varying 3 parameters and stored
results in the data matrix. The first column will contain CAGR
and columns 2:4 will contain parameters values.
It is quite hard to navigate this plot.
Ideally, you would want to select a ranges for parameters and
check corresponding system CAGRs, or alternatively select a range
of CAGRs and see what parameters produced them. The amazing
Acinonyx - iPlots eXtreme package
allows this Interactivity.
