[ncl-talk] XY Plot with Precip vs Time

[Melissa Lazenby]

Dear All NCL Users

I am having trouble displaying my x-axis correctly for an XY plot with precip anomalies vs time.
Below is the figure and code:
[cid:8e9bc557-0b88-48b3-9336-a13f3597a8c7]

I just would like to have my x-axis represent my time data which is in years from 1856-1890.

Any help would be greatly appreciated.
