To minimize future questions to ncl-talk, I wrote the attached.

*YOU* must show some effort.

*Look* at the output from every printVarSummary.

*Study* the documentation for "lonFlip"

>> After calculating SPI, I need to have a xy plot. My problem is that SPI has 3 dimensions, as you know to plot a xy plot 1 dimensional variables are needed. So my question is how can I convert 3 dimensinal SPI to 1 dimensinal. I need to plot SPI for whole Africa cntinent, not specific lat/lon.
