latitude vs. time (high-level plot interface)
Please note that this interface expects the data to be dimensioned as x(lat,time). This may require you to reorder your data.
gsn_csm_lat_time is the plot
interface that creates latitude v.s. time plots.
ShadeLtGtContour and gsnContourZeroLineThicknessF are the shea utility functions that shade the regions and add a zero line contour. Note: ShadeLtGtContour has been superceded by the more versatile gsn_contour_shade. We recommend you use this instead.
