Display heatmap #41

Closed magikker closed 11 years ago

magikker commented 11 years ago

For a given treeset and distance function display the heatmap of the all-to-all distance matrix.

Not completely certain how to go about it, but I know gnuplot can display heatmaps, so I'll look into displaying the heatmaps that way after I check the distance measures and clustering functions.

This would be another way to compare your RF distance measures: should have identical heat maps to external heat maps over same data sets.

Yep, it a nice "eye-check" when working with distances. It basically shows if the the order in which the trees are file matters.... so it could be a good way to take a quick look at the burn-in stuff too.

I added a function (currently in my clustering file because of the helper functions from my cluster displays) that allows TreeHouse to display a heatmap of a given set of trees using gnuplot. It also saves the generated heatmap to a .png file in the temp directory.

If we decide not to use gnuplot in the future that's one thing, but it was not extremely difficult to implement, and could also be useful while working on other projects within TreeHouse. So for now we have this functionality using gnuplot.
