[Matplotlib-users] latex label using string variable

[manouchk <man...@gm...>]

Hi,

My little problem is simple. I want to use a variable to define labels on a 
graph. If I want to create a fraction, I have to use function \frac but when 
I do that :
ylab="$RRR [\frac{R(300K)}{R(10K)}]$"
The value stored in ylab is :
'$RRR [\x0crac{R(300K)}{R(10K)}]$'

So how to put "\f" in a variable in python?

Hi,

I'd advise to use 'raw strings' like:
ylab = r'$RRR [\frac{R(300K)}{R(10K)}]$'
If you then type 'ylab' in interative mode, you'll see:
'$RRR [\\frac{R(300K)}{R(10K)}]$'
Voila: Backslashes get escaped automatically.

Cheers
Christian

You either have to escape the \ :
     ylab=3D"$RRR [\\frac{R(300K)}{R(10K)}]$"

or use raw strings:
     ylab=3Dr"$RRR [\frac{R(300K)}{R(10K)}]$"

Ok thank you, I didn't have already integrated the concept of raw string! B=

now it is.
