Now that we have our meshgrid, we can plot our 3D data: Now, we can adjust the view of plot there are three parameters that we control for this: elevation, azimuthal angle (in the x-y plane), and distance from the axes, which roughly correspond to the spherical coordinate system values of , , and r, respectively. If not provided, the Now we display our image with the following command: origin images are typically shown with their origin as the top left corner, so by using origin='lower' we force the origin to be a the bottom left. Check them out at https://kepler.gl/. Each layer-related data sits in a text file with columns of x, y, z and G. The delimiter is white space. The term "heatmap" usually refers to a cartesian plot with data visualized as colored rectangular tiles, which is the subject of this page. 1.54 Heatmaps are a great way to visualize a dataset, methods for visualizing the data are getting explored constantly and 3D heatmap is one of the ways to plot data. Let's create our (all-file unifying) color-scale. I had to refactor things a little bit more in this. I am setting the azimuthal angle to 225 because we want the x and y axes to meet at (0, 0).
