This week we decided to add a slider feature to our UI. This will better display a feature we had already implemented: collapsing low persistence nodes. The slider will correspond to the graph on the right side of the featured image. Here is a better picture:

Points above the line are points that aren’t simplified and points below are those that get simplified, based on persistence. This line will be represented by our slider, and all bars to the left of the slider will collapse corresponding nodes. I already have half the slider implemented, but the full functionality I’ll hopefully have done by next week. Here is what it looks like so far, with updated barcode:

Right now nothing is collapsing, but ideally all bars to the left of the vertical line in the barcode will collapse the graph so it’s easier to read.

I also get to visit the University of Arizona from 11/30 – 12/3! I’m exited to talk more with Carlos Scheidegger and Josh Levine about their vis lab and the research they’ll be working on in the fall. I’m definitely considering UA for my PhD so this will be really helpful in making my decision.
