Details

placeLabels steps through the points indexed by x and y, allowing the operator to manually place the labels for each point. Each point is "flagged" by displaying a small colored circle (red by default). When the label for that point has been placed, the original symbol is displayed and the next point is flagged.

Each point and label can have different colors and backgrounds.
