Matplotlib で水平線と垂直線をプロットするための hlines と vlines プロットされた水平線と垂直線を自動的に変更してデータ座標に対する相対位置を維持する場合は、ラインをプロットするために hlines と vlines を使用する必要があります。 The code below illustrates some different uses of ax.vlines and ax.hlines. hline = refline(___) returns the reference line object hline using any of the input arguments in the previous syntaxes.

2020-04-12 · The axhline() function in pyplot module of matplotlib library is used to add a horizontal line across the axis. Syntax: matplotlib.pyplot.axhline(y=0, xmin=0, xmax=1, **kwargs) Parameters: This method accept the following parameters that are described below: y: This parameter is an optional and it is position in data coordinates of the horizontal line.

Presently all of the lines kwargs (hlines,vlines, tlines, alines) assume the main panel axes.I was thinking to add a panel kwarg to the lines dict, rather than have the kwarg available to addplot.. I will come up with something, and include it in my next pull request, which I hope to make by the end of this week. Python matplotlib.hline Method Example.
