The first parameter that we must feed into the cv2.line() function is the image we want to draw it on. We will be using what we created with numpy, whiteblankimage. This provides a perfect clean white background, in which we can place our line shape. The second parameter we must spe...

If your data points clearly will not fit a linear regression (a straight line through all data points), it might be ideal for polynomial regression.Polynomial regression, like linear regression, uses the relationship between the variables x and y to find the best way to draw a line through ...

axvline:绘制垂直线,使用的是轴坐标系统 ''' x: 垂直线的数据坐标中的x位置, 使用的是像素坐标系 ymin: 应介于0和1之间,0是绘图的底部,1是绘图的顶部, 使用的是轴坐标系。 ymax: 应介于0和1之间,0是绘图的底部,1是绘图的顶部, 使用的是轴坐标系。
