The default extent is determined by the following conditions. Pixels have unit size in data coordinates. Their centers are on integer coordinates, and their center coordinates range from 0 to columns-1 horizontally and from 0 to rows-1 vertically.
Witryna15 mar 2024 · To hide the axis value but to keep the axis tick labels, we can perform the following steps − Plot a line using the plot ( ) method. Set X and Y labels using x label and y label methods. Using plt.gca (), get the current axis, creating one if necessary. Use xaxis.set_ticklabels () with an empty list. Use yaxis.set_ticklabels () with an empty list. WitrynaCreate a binary image (of 0s and 1s) with several objects (circles, ellipses, squares, or random shapes).
