from matplotlib.ticker import EngFormatterax.xaxis.set_major_formatter(EngFormatter())使用axes对象的xaxis或yaxis属性，调用set_major(minor)_formatter(locator)函数，并传入类名。8、grid 自定义网格线可以突出数据范围。在Matplotlib中，可以使用轴线对象的网格函数创建和自定义网格。下面是一个垂直网格的例子:fig...
ax1.set_xlabel("x坐标轴")# Make the y-axis label, ticks and tick labels match the line color.ax1.set_ylabel("以e为底指数函数", color="b")ax1.tick_params("y", colors="b")# ax1 shares x-axis with ax2.ax2 = ax1.twinx()s2 = np.cos(t**2)ax2.plot(t,s2,c="r",ls="...
_, ax = plt.subplots() # Draw bars, position them in the center of the tick mark on the x-axis ax.bar(x_data, y_data, color = '#539caf', align = 'center') # Draw error bars to show standard deviation, set ls to 'none' # to remove line between points ax.errorbar(x_data...
create a twin of Axes for generating a plot with a sharex x-axis but independent y axis. The y-axis of self will have ticks on left and the returned axes will have ticks on the right. 意思就是,创建了一个独立的Y轴,共享了X轴。双坐标轴! 类似的还有twiny() ax1.xaxis.set_major_for...
轴空间Axes包含两个轴Axis对象,它们负责数据范围(数据范围也能通过axes.Axes.set_xlim()与axes.Axes.set_ylim()控制)。每个轴坐标都有一个标题,通过set_title()设置,一个横轴标签,通过set_xlabel设置,一个竖轴标签,通过set_ylabel设置。 Axes类及其成员函数是使用面向对象接口的最主要入口点。
ax1.set_title('Sharing Y axis') ax2.scatter(x, y) fig, axs = plt.subplots(2, 2, subplot_kw=dict(projection="polar")) axs[0, 0].plot(x, y) axs[1, 1].scatter(x, y) 在Python的matplotlib库中,axes.flat是一个迭代器,用于在多个子图(subplots)上进行迭代。当你创建一个子图网格时,...
