I tried to use latex format in matplot lib but it is not giving me space in a line. Here is my code 

```
plt.figure(103)
plt.title('$V_x mean and fitting$')
plt.plot(vx_mean_fit[sig_fit],Sig[sig_fit],label='$Vx mean fit$')
plt.xlabel('$V_x$')
plt.ylabel('$z/d$')
plt.legend()

```

And here is my picture. Any idea why there is no space in title?
