Conclusion of drawing horizontal and vertical lines in matplotlib in this tutorial we will introduce two methods to draw horizontal and vertical lines in matplotlib.
Matplotlib vertical line label.
Plot vertical lines at each x from ymin to ymax.
Matplotlib pyplot vlines x ymin ymax colors k linestyles solid label data none kwargs source plot vertical lines.
It brings inconvience if the tick label text is too long like overlapping between adjacent label texts.
Scalar or 1d array like.
Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot.

Each of these elements has a different purpose as follows.

The purpose is to make it easy for the viewer to know the name or kind of data.
Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot.
Ymax scalar optional default.
Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot.
Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot.
