I developed an inelegant solution.我开发了一个优雅的解决方案。Consider that we have the X axis and also a list of labels for each point in X.考虑我们有X轴,还有X中每个点的标签列表。 Example: 例: plt.plot(x,y) plt.xticks(range(0,len(x)),xlabels,rotation=45) plt.show() 1. 2. ...
faces = fetch_olivetti_faces().images for i in range(5): for j in range(5): #隐藏x和y轴刻度和标签 ax[i,j].xaxis.set_major_locator(plt.NullLocator()) ax[i,j].yaxis.set_major_locator(plt.NullLocator()) ax[i,j].imshow(faces[10 * i + j], cmap='bone') 1. 2. 3. 4. 5...

Especially since what is missing most from this function is a way to limit the frequency axis span, but instead these parameters appear to filter/rescale the actual spectrum values before they get shown. Suggested improvement Please just document what these parameters are here for like all others...
