I have a graph of two lines, one of type solid, the other of type dashed, however the legend shows them both as solid. Is there a way to have the dashed line show up in the legend to accurately reflect what line matches what legend data?
Though this feature is currently not available, you can workaround this problem by setting legendMarkerType to "triangle" with color same as that of chart background. Here is a jsfiddle.
legendMarkerType: "triangle",
legendMarkerColor :"white",
