Positioning label on CPTBarPlot (Core-Plot)

Question

I am trying to change default position of labels in Bar chart with Core-Plot. I am using this method:

return textLayer = [[CPTTextLayer alloc] initWithText:@"2222" style:textStyle];

I get this result:

But I want to appear as follows:

Any idea? I tried to find answer on documentation, but I has been impossible.

Answer 1

Use a negative labelOffset for the bar plot. The default is +10 which puts the labels 10 pixels above the bars. This property is inherited from CPTPlot so it works for all plot types, although the default value and behavior varies somewhat.
