[ncl-talk] bar chart

[Mary Haley]

I'm sorry, but I don't know what you mean by "I failed to add legend,
vpWidthF and vpHeightF to this example".

Do you mean you are trying to set a height and width for your legend and
it's not working? Are you using gsn_legend_ndc to create a legend? If not,
then what kind of legend are you trying to create?

If you have a problem with an NCL script, you MUST tell us what you have
tried so far, and show us some code and explain in detail what you are
trying to do.
