Dear Atakan (and all),
I tried it, but still got an error :-(. *My code is:*
from pyx import *
from pylab import *
from pyx import text as pyxtext
pyxtext.set(mode='latex')
pyxtext.preamble(r'\usepackage{mathabx}')
x=arange(1,5,0.1)
y=exp(-(x-3.0)**2/(2.0*0.5**2))/sqrt(2.0*pi*0.5**2)
###################### Let's pyx this!
g=graph.graphxy(width=8,y=graph.axis.linear(title=r"Fraction of DM
halos"),x=graph.axis.linear(min=1,title=r"Mass ($10^{11}M_{\sun}$)"))
g.plot(graph.data.values(x=x,y=y),styles=[graph.style.histogram()])
g.writeEPSfile("testhistogram")
* And the error is:*
pyx.text.TexResultError: unhandled TeX response (might be an error)
The expression passed to TeX was:
\ProcessPyXBox{\setbox0\hbox{$\vcenter{\vrule
width0pt}$}\PyXDimenVShift=\ht0\setbox0\hbox{{\gdef\PyXBoxHAlign{0.50000}\gdef\PyXFlushHAlign{0.50000}\PyXragged{}Mass
($10^{11}M_{\sun}$)}}\lower\PyXDimenVShift\box0%
}{12}%
\PyXInput{17}%
After parsing the return message from TeX, the following was left:
*
*! Undefined control sequence.
<argument> ...}\PyXragged {}Mass ($10^{11}M_{\sun
}$)}}\lower
\PyXDimenVShif...
<*> }{12}
(cut after 5 lines, increase errordebug for more output)
