Contour Plots of Mathematical Functions
npm install contour_plotA D3 plugin to draw contour plots of 2D functions.
Uses the marching squares algorithm from d3.geom.contour to generate contour lines.
This project is a work in progress, and not ready for public consumption. Notably this doesn't
generate
If you use NPM, npm install contour_plot. Otherwise, download the latest
release.
Draw the Goldstein Price function:
``javascript
function goldsteinPrice(x, y) {
return (1. + Math.pow(x + y + 1, 2) *
(19 - 14x + 3xx - 14 y + 6 x x + 3 y y))
(30 + Math.pow(2x-3y, 2)(18 - 32x + 12 x x + 48y - 36 x y + 27 y y));
}
var plot = contour_plot.ContourPlot()
.f(goldsteinPrice)
.drawAxis(true)
.xDomain([-2, 2])
.yDomain([1, -2])
.colourRange(["white", "green"]);
var elements = plot(d3.select("#contour_graph"));
``
Should produce something like:
