woreda graph incl. woreda cropland curve

Okay, thus a graph with a curve incl std dev for the whole woreda and, in the same graph (?), a curve for only the woreda-cropland area. (Or the same graph frame with either one or the other depending on the user choice).

Problem here is that I need help with producing the cropland area map. (the s4a tiff indicates various agland categories which I want to combine with another cropland shape).

• Locate cropland area dataset
• Intersect cropland with result
• Return avg(yield) for npk columns for woreda
