canvasPlot.js

Minimal HTML5 Canvas/JavaScript 2D data plotting library.

I am too lazy to explain hows and whys, just take a look at the example files:

• plot.html - basic data plotting;
• gridAutoLinear.html - automatic grid for linear maps;
• gridAutoSemiLogX.html - automatic grid for semilogx maps;
• resample.html - linear resample;
• spectrum.html - spectrum analyzer:
• scope.html - oscilloscope.

The experimental folder contains stuff that I just didn't want to throw away.

TODO

• grid ticks, axis labels, etc.;
• higher-order interpolators and resamplers;
• idiotic APIs for the laziest;
• serious API review;
• serious documentation;
• the HTML/CSS is probably somewhat broken;
• minified version;
• releases/stable APIs?
• Node.js package?
• split scope/spectrum analyser in a separate project?
• time persistence of scope signals?
• analysis of continuous audio streams (ScriptProcessorNode, AudioWorker, Transferable Objects, etc.)?
• measuring?
• different line drawers (points, areas, etc.)?
• 3D (WebGL)?
• optimizations?
