This is the kind of check I am envisioning. |
Fixes Unidata#2785. Currently, BarbPlot is happy to attempt to plot very large wind barbs, but if the size becomes too large, memory usage becomes an issue, leading to system hangs. This commit adds a check to make sure the wind barbs will not consist of so many pennants that memory could be an issue.
