进行初始化 plt.figure(figsize = (8,6)) ax = plt.gca()
调整坐标轴范围 x轴 ax.set_xlim() y轴 ax.set_ylim() 设置在 0 - 8 之间 ax.set_xlim(0,8) ax.set_ylim(0,8)
设置 x 轴 y 轴 标题 ("内容",fontsize = ,color = ,alpha = , bbox = ,) ax.set_xlabel() ax.set_ylabel() 参数示例 ax.set_xlabel("X轴",fontsize = 14,color = 'b',alpha = 0.7,bbox=dict(boxstyle='round,pad=0.5', fc='yellow', ec='blue',lw=1 ,alpha=0.7)) ax.set_ylabel("Y轴",fontsize = 14,color = 'b',alpha = 0.7,bbox=dict(boxstyle='round,pad=0.5', fc='yellow', ec='blue',lw=1 ,alpha=0.7))
修改默认刻度文字 (列表 , family = , fontsize = ,) ax.set_xticklabels() ax.set_yticklabels() ax.set_xticklabels(['A','B','C','D','E','F','G']) ax.set_yticklabels(['鉴','图','化','视','可','注','关'], family = 'SimHei',fontsize = 14)
突出主副刻度 使用 tick_params 对刻度线进行调整 tick_params(which = , length = , labelsize = ,) tick_params(which='major',length=8,labelsize=10) tick_params(which='minor',length=4)
调整 坐标轴 刻度 距离
默认刻度 locator 位置 MultipleLocator 样式 FormatStrFormatter from matplotlib.ticker import MultipleLocator, FormatStrFormatter xmajorLocator = MultipleLocator(1) ax.xaxis.set_major_locator(xmajorLocator) ymajorLocator = MultipleLocator(1) ax.yaxis.set_major_locator(ymajorLocator) xminorLocator = MultipleLocator(0.25) ax.xaxis.set_minor_locator(xminorLocator) yminorLocator = MultipleLocator(0.25) ax.yaxis.set_minor_locator(yminorLocator) MultipleLocator(1) 表示刻度之间的间隔为 1
