To set color for bars in a Bar Plot using Matplotlib PyPlot API, callmatplotlib.pyplot.bar()function, and pass required color value(s) tocolorparameter ofbar()function. The definition of matplotlib.pyplot.bar() function withcolorparameter is </> Copy bar(x, height, color=None) Of course,...
Matplotlib基本参数设置 1. 添加图标题,坐标轴标题,图例 添加图标题有plt.xlabel()和axes.set_xlabel()方法,添加坐标轴标题和图例也基本类似,其中注意的是绝大多数的 plt 函数都可以直接转换成 axes 方法(例如 plt.plot() → axes.plot()、 plt.legend() → axes.legend() 等),但是并非所有的命令都可以这样...
当使用颜色图(colormap)时,我们可能想要栅格化colorbar的刻度: importmatplotlib.pyplotaspltimportnumpyasnp# 创建数据x=np.linspace(0,10,100)y=np.linspace(0,10,100)X,Y=np.meshgrid(x,y)Z=np.sin(X)*np.cos(Y)# 创建图形fig,ax=plt.subplots()im=ax.imshow(Z,cmap='viridis')# 添...
