st: visualizing stpiece models with graph dot?

[SCHNELL Philipp <philipp.schnell@ined.fr>]

Hello,
I did a piecewise constant exponential model (with 7 covariates) and 
would like to visualize the results! Is it possible to use the
graph dot command to plot the hazard ratio of covariates (in a 
particular order - from high to low!)? If so, how do I do that?

It should look like this:

                       covariate6  |...........o....
                       covariate1  |.........o......
                       covariate3  |.......o........
                                   +----------------
                                   hazard ratio


the command to plot should be:

graph dot numerical variable , over(categorical variable 
[,sort((stat)varname)])

but my problems are:
a) how to introduce my covariates instead of a categorical var?
b) how to sort?

Thanks for your help and suggestions!

Philipp
