HpxMollweideAxes.axvline(x=0, ymin=0, ymax=1, **kwargs)¶

Add a vertical line across the axes.

Call signature:

axvline(x=0, ymin=0, ymax=1, **kwargs)

Draw a vertical line at x from ymin to ymax. With the default values of ymin = 0 and ymax = 1, this line will always span the vertical extent of the axes, regardless of the ylim settings, even if you change them, e.g., with the set_ylim() command. That is, the vertical extent is in axes coords: 0=bottom, 0.5=middle, 1.0=top but the x location is in data coordinates.

Return value is the Line2D instance. kwargs are the same as kwargs to plot, and can be used to control the line properties. e.g.,

draw a thick red vline at x = 0 that spans the yrange:
```
>>> axvline(linewidth=4, color='r')
```
draw a default vline at x = 1 that spans the yrange:
```
>>> axvline(x=1)
```
draw a default vline at x = .5 that spans the the middle half of the yrange:
```
>>> axvline(x=.5, ymin=0.25, ymax=0.75)
```

Valid kwargs are Line2D properties, with the exception of ‘transform’:
