The closest option I found was a contour plot, but I would prefer a smooth gradient, such as the last example in the following link (minus the data points):. Histograms What is a histogram? A histogram is a plot that lets you discover, and show, the underlying frequency distribution (shape) of a set of continuous data. If [int, int], the number of bins in each dimension (nx, ny = bins). The return values are a range e, which correspond to the edges of the bins, and counts containing the number of elements of v in each bin. If density is True, the weights are normalized, so that the integral of the density over the range remains 1. But if your data represents single measurements of a function that has meaningful values away from those measured points, you probably want to interpolate between those points. The bin specification: If int, the number of bins for the two dimensions (nx=ny=bins). If you have a simple question about this example contact us at VTKExamplesProject If your question is more complex and may require extended discussion, please use the VTK Discourse Forum. Gadfly can work with data supplied as either a DataFrame or as plain AbstractArrays.
