一、实线（Solid Line）实线是最常见的线条类型之一，它通过连接相邻的数据点来形成连续的线段。在matplotlib中，我们可以使用plot函数来绘制实线，例如：```import matplotlib.pyplot as plt x = [1, 2, 3, 4, 5]y = [2, 4, 6, 8, 10]plt.plot(x, y, linestyle='-', label='Solid Line')```...

plt.title("Scatterplot with line of best fit grouped by number ofcylinders", fontsize=20) 每个回归线都在自己的列中 或者,您可以在其自己的列中显示每个组的最佳拟合线。你可以通过在里面设置参数来实现这一点。 # Import Data df = pd.read_csv("https://raw.githubusercontent.com/selva86/datasets...
To make a legend for lines which already exist on the axes (via plot for instance), simply call this function with an iterable of strings, one for each legend item. For example:: ax.plot([1, 2, 3]) ax.legend(['A simple line'])Note:This way of using is discouraged, because the...
