# contour_plot A 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 ## Installing If you use NPM, `npm install contour_plot`. Otherwise, download the [latest release](https://github.com/benfred/contour_plot/releases/latest). ## Example Draw the [Goldstein Price](https://en.wikipedia.org/wiki/File:Goldstein_Price_function.pdf) function: ```javascript function goldsteinPrice(x, y) { return (1. + Math.pow(x + y + 1, 2) * (19 - 14*x + 3*x*x - 14 * y + 6 * x * x + 3 * y * y)) * (30 + Math.pow(2*x-3*y, 2)*(18 - 32*x + 12 * x * x + 48*y - 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:
