  • This was done above when showing the previous default colormap. Here are some more. Warning! Once you change the colormap, it will keep that colormap for all subsequent 3D plots within the same figure or MATLAB session until you use close, or open a new figure window.
  • The colorbar is technically your legend for an image (i.e. intensity/color range pointing to specific pixels). If you want to additionally describe, you can use title() to place it above your image. - gevang Oct 15 '12 at 19:49

  • With the extra time at the moment I thought I'd generate some images of the Mandlebrot set. Been good fun but I am having issues saving the produced imagesc at it's original resolution. The code below produces an image at a resolution of 20001 x 20001 and all I want to do is save it at this resolution with the applied colormap.

I would like to do a scatterplot of x and y with a different marker colour for each subject, and display a colorbar/legend that shows what colour corresponds to which subject.

  • nexttile creates an axes object and places it into the next empty tile of the tiled chart layout that is in the current figure. If there is no layout in the current figure, then nexttile creates a new layout and configures it using the 'flow' tile arrangement. The resulting axes object is the current axes, so the next plotting command can plot into it.Bench (Traylor 625)¶ Phantom's $(x, y, z)$ is aligned with bench's $(x, y, -z)$ in the original left-handed coordinates, and with $(x, y, z)$ in a right-handed interpretation.

  • Jan 08, 2019 · After lots of research, I finally find out the problem. It looks like Matlab is trying to launch functions (estimateGeometricTransform, imwarp) BEFORE the previous statements are completed (Which makes no sense at all!!). But I solved the problem with some "pause(1)" to oblige Matlab to wait and do all statement in the logical order...
