ios - Core-Plot DataLabel Z-Ordering -


i try add data labels bar graph in core-plot (on ios). user selects individual plots , values shown.

the main problem shown in image, other plots overdraw data labels.

image showing problem

is possible have labels @ top?

as user sets ordering of bars, cannot reorder bars. (also if did, user experience terrible whole graph appearance change on selection.)

other possibility: can reorder plots z-ordering have positions remain unchanged?

any other ideas? tried cptplotspaceannotations, cannot align them on bar precise enough (see "1037" label @ year (x-axis) 1980).

i came solution myself: remove plot , add back. in way plot raised in z-hierarchy.

[self.graph removeplot:plot]; [self.graph addplot:plot];
