plt.savefig('linechart.png') This example creates a smooth, curved line chart representing a sine wave, often used to model periodic phenomena like sound waves or electrical signals. Usingnumpy, we generate an arraytfor time values from 0 to 3 seconds in 0.01-second increments, andscalculates...
第53 行使用 ax.axvline() 为动态图表添加一条推进线。 第54-64 行则是对图表刻度、轴脊等 属性进设置。 第75 行采用ax.yaxis.set_major_formatter(ticker.StrMethodFormatter('{x:,.0f}'))定制化刻度标签形式,此方法对绘制定制化的刻度标签非常有用,希望感兴趣的同学们可以多看看官网的教程。 第86 行ax...
