Dear all,

In the following graph bar I want to add as a dot or dash the carg variable, and because of its relative small size I would like it to appear on the right axis.

Is this possible with graph bar or I must follow a different alternative? I've tried unsuccessfully with twoway bar.

Any suggestion is more than welcome.

Regards,
Nikos
