Changing pixel figure coordinates when using imshow
11 views (last 30 days)
When I use imshow to plot the pixels represented by a matrix, each pixel is centered in the figure at its matrix coordinates (e.g. the pixel on row 1, column 1 is centered at figure coordinates (1,1)).
Is it possible to change this so that a specific corner of each pixel is positioned at its matrix coordinates? For example, can the pixel on row 1, column 1 be plotted with its lower right corner at figure coordinates (1,1), and so on for all the remaining pixels?
