問題1:調整ColoBar的高度與圖片一致
參考鏈接:https://stackoverflow.com/questions/18195758/set-matplotlib-colorbar-size-to-match-graph
代碼:
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np
plt.figure()
ax = plt.gca()
im = ax.imshow(np.arange(100).reshape((10,10)))
# create an axes on the right side of ax. The width of cax will be 5%
# of ax and the padding between cax and ax will be fixed at 0.05 inch.
divider = make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)
plt.colorbar(im, cax=cax)
問題2: 調整plt.imshow在座標系中的位置
參考鏈接:https://matplotlib.org/3.1.1/api/_as_gen/matplotlib.pyplot.imshow.html
代碼:
plt.imshow(extent=(left,right,bottom,up))
問題3:設置座標軸
參考鏈接:不可考
代碼:
plt.xlim(0,100)
plt.xticks([0,50,100])
問題4:設置座標軸和ColorBar的字體大小
參考鏈接:不可考
代碼:
plt.tick_parms(labelsize=25)
cbar = plt.colorbar()
cbar.ax.tick_params(labelsize=25)
