Is there a way to set the Axis Ticks to be non-numeric in CorePlot. So that it doesn't display 1,2,3,4,5.... on the axis, but rather corresponding stings A,B,C,D?
Just create new axis labels from locations through
func axis(_ axis: CPTAxis, shouldUpdateAxisLabelsAtLocations locations: Set<NSNumber>) -> Bool {
var newLabels: Set<CPTAxisLabel> = []
for tickLocation in locations {
let theLabelTextStyle: CPTTextStyle? = nil
let labelString = "?"
let newLabelLayer = CPTTextLayer(text: labelString, style: theLabelTextStyle)
let newLabel = CPTAxisLabel(contentLayer: newLabelLayer)
newLabel.tickLocation = tickLocation
newLabel.offset = labelOffset
newLabel.rotation = labelRotation
newLabels.insert(newLabel)
}
axis.axisLabels = newLabels
return false
}
func axisShouldRelabel(_ axis: CPTAxis) -> Bool { return true }
func axis(_ axis: CPTAxis, shouldUpdateMinorAxisLabelsAtLocations locations: Set) -> Bool { return true }
