我有以下情节:旋转Matplotlib刻度标记导致奇怪的间隔发出
我想使x轴蜱通过〜40度旋转蜱更具有可读性。所以从:
plt.xticks(list(range(0, width)), list(df_100.columns), rotation='90', fontsize=16)
要:
plt.xticks(list(range(0, width)), list(df_100.columns), rotation='40', fontsize=16)
当我这样做,不过,我得到一些疯狂的间距问题:
(忽略的变化在颜色...)
导致此问题的原因是什么?我该如何解决它?下面是一个最小工作示例:
import matplotlib.pyplot as plt
import numpy as np
# Z is your data set
N = 100
height = df_100.shape[0]
width = df_100.shape[1]
# Z = np.random.random((100, 29))
# G is a NxNx3 matrix
G = np.zeros((height,width,3))
# Where we set the RGB for each pixel
G[Z>0.5] = [1, 1, 1]
G[Z<0.5] = [0.25, 0.25, 0.25]
fig, ax = plt.subplots(figsize=(20, 10))
ax.imshow(G, interpolation='none')
ax.set_aspect('auto')
ax.grid(None)
ax.xaxis.tick_top()
plt.xticks(list(range(0, width)), list(df_100.columns), rotation='45', fontsize=16)
plt.yticks([0, df_100.shape[0] - 1], [1, df_100.shape[0]], fontsize=20)
plt.tight_layout()
plt.show()
图像显示不正确,似乎也没有颜色变化... –
