在不同平面上绘制二维条形图。
本实例制作了一个3d图,其中有二维条形图投射到平面y=0,y=1,等。

To demonstrate this, we color the first bar of each set cyan. cs = [c] * len (xs) cs[ 0 ] = 'c' # Plot the bar graph given by xs and ys on the plane y=k with 80% opacity. ax.bar(xs, ys, zs = k, zdir = 'y' , color = cs, alpha = 0.8 ) ax.set_xlabel( 'X' ) ax.set_ylabel( 'Y' ) ax.set_zlabel( 'Z' ) # On the y axis let's only label the discrete values that we have data for. ax.set_yticks(yticks) plt.show() |
