Good morning,
I am running openSuSE 12.2, and this morning I upgraded
matplotlib to v1.3, and now I am having a problem with suptitle.
I use the following lines to put a title and legend onto a
plot figure
import matplotlib.pyplot as plt
plt.figure(1)
plt.suptitle( "Study# : " + os.path.basename(
inImage_IO.IO_FileName ) + \
"\n" + "{ Acquired : " + \
AcqDateTime.strftime( "%b %d, %Y - $T_o$ @ %H:%M:%S" ) + " }", \
y=0.98, weight="roman", size="large" )
plt.suptitle( "{Creation Date : " + AnalysisTOD + "}",
x=0.86, y=0.03, weight="roman", size="x-small" )
Under v1.3, I only get the 'Creation Date : ...' text at the
bottom of the figure the 'Study# ...' string is not present
at the top. If I change
it to
import matplotlib.pyplot as plt
plt.figure(1)
plt.suptitle( "Study# : ", y=0.98, weight="roman", size="large" )
plt.suptitle( "{Creation Date : " + AnalysisTOD + "}",
x=0.86, y=0.03, weight="roman", size="x-small" )
the 'Creation Date : ...' text at the bottom of the figure
the 'Study# : ' string is at the top.
So the problem is in the string construct in the first
example. Does anybody know of a way to get around this?
Thanks in advance
Peter
Oh, wow... we didn't think anybody was using that "misfeature".
This was a bug we fixed for 1.3, in that users complained that
calling plt.title() would update an existing title, but
plt.suptitle() would not (multiple calls would just result in
text overlaid on top of each other). We fixed this for 1.3 so
that there is a single text object that is kept and is revised in
subsequent calls to suptitle(). To get what you want, you will
have to consolidate those strings into one.
Cheers!
Ben
Thanks for getting back to me, but I have tried to do as you
suggest, but to no avail, and here I apologise for my lack of
knowledge of python/matplotlib.
I consolidated the strings into one, titleStr
titleStr = "Study# : " + os.path.basename(
inImage_IO.IO_FileName ) + \
"\n" + "{ Acquired : " + \
AcqDateTime.strftime( "%b %d, %Y - $T_o$ @
%H:%M:%S" ) + " }"
plt.suptitle( titleStr, y=0.98, weight="roman", size="large" )
which should write the string
'Study# : Pos9.img\n{ Acquired : Feb 18, 2003 - $T_o$ @
14:55:02 }'
at the top of the figure, but it did not, so I thought it is the
"\n", and tried
titleStr = "Study# : " + os.path.basename(
inImage_IO.IO_FileName )
plt.suptitle( titleStr, y=0.98, weight="roman", size="large" )
which should write the string
'Study# : Pos9.img'
and this again failed to write the suptitle in the figure.
Am I being dumb (rhetorical)? What is the best way to consolidate
the strings to work with suptitle, many thanks in advance.
Cheers
Peter
No issues here. Let's try simplifying it further and further. Try
the following script.
import matplotlib.pyplot as plt
plt.suptitle("Study# : Pos9.img")
plt.show()
Does that work for you? If it does, iterate on that code example,
adding pieces back into it and see when it breaks.
Ben Root
The example works, and changing it to
import matplotlib.pyplot as plt
plt.suptitle( "Study# : Pos9.img\n{ Acquired : Feb 18, 2003 - $T_o$ @
14:55:02 }")
plt.show()
also works.
Though now, I need to apologise, in my original email I should have
added that I am using
from matplotlib.backends.backend_pdf import PdfPages
to write a pdf file of the save the figure.
I extended the example to a small script
from matplotlib.backends.backend_pdf import PdfPages
import matplotlib.pyplot as plt
PDF_Filename = "Test.pdf"
OutPDF = PdfPages( PDF_Filename )
plt.suptitle("Study# : Pos9.img\n{ Acquired : Feb 18, 2003 - $T_o$
@ 14:55:02 }")
plt.savefig( OutPDF, dpi=600, format="pdf" )
OutPDF.close()
and this also works, the text is now written correctly in Test.pdf.
However, if I add a second call to plt.suptitle in the script the text
added from the first call is removed, which is what was refered to in
the first response.
Cheers
Peter
