I have a graph with a three-valued legend (three categorical values of “Location”). After having made the graph, I changed the value of one of the locations by dragging “location” to the left, changing the value and then dragging “location” back to the right. The graph reacted to this change, but incompletely. It changed the colors associated with the values, but didn’t change the legend to match. So, the attached graph has a legend that doesn’t match the colors on the graph.
