Question

I’m hacking up a proof-of-concept for a lightweight, generic machine learning algorithm running in Javascript to be used in web apps.

I need a way of quickly visualising large amounts of data by say, plotting 50,000 floats as a function of their index in an array.

Is there anything that can generate such a graph straight from the array of data? Somebody pointed me to visualize.js but I don’t really want to screw around with generating markup during the learning process, Javascript is slow enough as it is.

What would be the easiest way to do this?

Answer 1

Try jqPlot: http://www.jqplot.com

It has more options than you can imagine for customizing it and it’ll display every kind of graph you could ever want. The documentation is a bit convoluted, but other then that it’ss a pretty fast setup.
