For vs. Image


Recommended Posts

Hi pixy people,

My challenge is to optimize in term of speed the following plot:


My plot is a mix of D3 and pixi. Because SVG (D3.js) is very very very greedy for the browser when you have a lot of points to plot, I used pixi with the hope to improve the performance.

The final version of my plot will contain colors and a html5 slider to change these colors. The source of data is a big JSON with possibly up to 300 000 rows.

As you can see, I used a loop but it's very slow. I'm a total newbie in pixi.js and I look for a possible "rastering" pixi solution like image() on Matlab or R.

I hope I'm sufficiently clear.
