I added an example program which illustrates my idea using transformation of
axes-coord. to screen-coord. and from screen-coord. to fig-coord.
point_screen = ax.transAxes.transform_point(point_ax)
point_fig = fig.transFigure.inverted().transform_point(point_screen)
Actually, I wanted my text to not move relative to one of the x-axis labels.
I found the solution with some tinkering. Basically, I needed to grab the transformation of the labels.
tx = ax.get_xticklabels()
text(1.5, 0.0, “some text”, transform=tx.get_transform())
To also get a constant offset:
text(1.5, 0.0, “some text”, transform=tx.get_transform() + ScaledTransformation(-.1,-.1, fig.dpi_scale_trans))

How do I get the coordinates of the ticks and their labels in a coordinate

I want to display some additional text near one of the ticklabels on the x
axis. Although I could get the coordinates for figtext using trial and
error, but is there a correct way of doing this (using transformations?) so
that my text does not move relative to the tick labels.
