linestyle:special feature used to change the style of the line. We mention it as dashed because our main objective is to create a dashed line graph. Read:Matplotlib plot bar chart Matplotlib dashed line example In the above sections, we discussed what a dashed line graph exactly means and wh...

折线图(line chart)是我们日常工作、学习中经常使用的一种图表,它可以直观的反映数据的变化趋势。 可视化结果: 直线:左上直线图形显示。 曲线:右上带有样式变化和标记的折线预览。 代码如下: def draw_line(): N = 8 t = np.linspace(0, 1, N) fig, (axA, axB) = plt.subplots(1, 2) # Line axA...
