[gradsusr] Plotting H/L's without using opengrads?

[Jennifer Adams]

Hi, Chrisopher,
You can use aminlocx() and aminlocy() to get the position of the grid box with an SLP minimum, and then use ‘draw string’ with the results to draw a big “L”.  Likewise, use amaxlocx() and amaxlocy() for the H’s position. You may have to restrict the domain a bit to isolate individual synoptic features.
