Matplotlib Vertical Line With Text

Adding titles to the x and y axis.

Matplotlib vertical line with text.

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. X position in data coordinates of the vertical line. Hlines and vlines to plot horizontal and vertical line in matplotlib. Ymin scalar optional default.

Axhline and axvline to plot horizontal and vertical lines in matplotlib. By default this is in data coordinates. Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot. The coordinate system can be changed using the transform parameter.

Sometimes it is necessary to rotate a text annotation in a matplotlib figure so that it is aligned with a line plotted on the figure axes. Class matplotlib text annotation text xy xytext none xycoords data textcoords none arrowprops none annotation clip none kwargs source bases. If fontdict is none the defaults are determined by rcparams. X position in data coordinates of the vertical line.

Axes annotation takes an argument rotation to allow a text label to be rotated and a naive implementation might be as follows. The underlying object that handles text is matplotlib text text ensuring that all text handling methods are consistent. Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot. Text is dealt with at this object level so a line of text can be given a specific font size style and colour.

Small additional suggestion say you want to label your line in the legend so that it has some meaning or take advantage of some of the easy to use options in plot then using hold the ylim from the current axis and the repmat is very useful. The created text instance. Ymax scalar optional default. An annotation is a text that can refer to a specific position xy.

The major items we use text for on a plot are. Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot. You can also make multiple vertical lines with some spacing using this technique. Should be between 0 and 1 0 being the bottom of the plot 1 the top of the plot.
