This is a plugin for Highcharts to display contour curves. It extends the existing [heatmap] module (which you must include) to display smooth gradients that interpolate the data points, and optionally contour lines over it. It can use either a list of discrete data points or a math function as an input. If you specify a discrete list of points, the surface can be triangulated in 3 ways: - Automatically, using [Delaunay] (In case your data is irregular or you are just lazy). You’ll have to include [Fast Delaunay Triangulation in JavaScript] - In a grid, where each row has grid_width data points. - Manually specifying a list of triangles.
