text element just above previous text element

Community matplotlib-users
#1

I like to have 2 or 3 text elements "stacked" on top of each other on top of a bar.

Currently it works for the first text element by doing:

height = bar.get_height()
xCorr = bar.get_x()
yCorr = 0.20 + height

txtax = axes.text(xCorr, yCorr, hstr)

trying to add the second text just above the previous one I tried this:

pCorr = yCorr + txtax.get_size() + 0.4
txtax = axes.text(xCorr, pCorr, hstrPerc)

It looks like my problem is that get_x() returns a value in ticks and txtax.get_size() is in pixels and I can't find a way to get at the height of the text element in ticks.

Can anyone please push me in the right direction.

I recommend you to use "annotate".

http://matplotlib.sourceforge.net/api/pyplot_api.html?highlight=annotate#matplotlib.pyplot.annotate

you may begin with something like below.

txt=plt.text(0.5, 0.5, "Test1")
plt.annotate("My Test2",
             xy=(0.5, 1.), xycoords=txt,
             xytext=(0, 5), textcoords="offset points",
             ha="center", va="bottom")

See belows for more details.

Finally figured it out after pulling some hear.

Using "axes.annotate" instead of "axes.text" worked for me, i.e. something like this:

axes.annotate(hstr, xy=(xCorr, yCorr), xytext=(0, 5), textcoords='offset points')

instead of what I did originally.
