[ncl-talk] Legend as a break in curve in a time-series plot

[Tabish Ansari]

Hi Adam,

Thanks. It worked.
Only issue was that since the 10 lines have a different maximum value and
the y-axis was set according to the
first plot (line 1) while rest of them were overlayed on it, some of them
were cut at the top. This was fixed
when I explicitly set the y axis limits (res at trYMaxF =  50). The resultant
plot looks nice.

There were some warnings though:
warning:NhlDraw: cannot draw Plot Member, ID 71, independently
warning:NhlDraw: cannot draw Plot Member, ID 112, independently
warning:NhlDraw: cannot draw Plot Member, ID 59, independently
warning:NhlDraw: cannot draw Plot Member, ID 29, independently
warning:NhlDraw: cannot draw Plot Member, ID 163, independently
warning:NhlDraw: cannot draw Plot Member, ID 204, independently
warning:NhlDraw: cannot draw Plot Member, ID 245, independently
warning:NhlDraw: cannot draw Plot Member, ID 156, independently
warning:NhlDraw: cannot draw Plot Member, ID 243, independently

Does this only refer to the rest of the 9 plots which were overlayed?
Or is it something to worry about?

Cheers,

Tabish
I got some warnings though:
