  Adding text relative to chart coordinates

I would like to add a text label to an XYChart at a specific x/y coordinate rather than x-pixel/y-pixel position. Is this possible?

Hi Pete,

If you would like to add text to a particular (x, y) data value coordinate, you may add a scatter layer with just one point at (x, y). The scatter layer can use a transparent symbol. Then attach the label to that symbol.

For example:

layer = c.addScatterLayer([x], [y], "", ChartDirector::DiamondSymbol, 1, ChartDirector::Transparent, ChartDirector::Transparent)
layer.addCustomDataLabel(0, 0, "My Label", "arialbd.ttf", 8, 0x000000).setAlignment(ChartDirector::Center)

Hope this can help.

Regards
