WebRecently I came up with an idea that using egui to simulate STM images, which is based on like matplotlib.pcolormesh, and the example is in the following:. The problem is that, though egui provides ColorImage to show the 2D data, the STM may contains shape other than … Webinterpolation='nearest' simply displays an image without trying to interpolate between pixels if the display resolution is not the same as the image resolution (which is most often the case). It will result an image in which pixels are displayed as a square of multiple pixels.
Webexample. vq = interp1 (x,v,xq) returns interpolated values of a 1-D function at specific query points using linear interpolation.
