Last label on xAxis is not showing

[saxxi]

Hi, I'm also not able to show the last label on the xAxis.

Example:

• I have 50 data points
• I'd like to to show the first [0], a mid point [24] and the last [49] labels

Here's a set of different attempts:

• view.xAxis.setLabelsToSkip(25)
• view.xAxis.setLabelsToSkip(24)
• view.xAxis.axisLabelModulus = 24

(I'm using avoidFirstLastClippingEnabled which is fitting only the first label)

I followed Stackoverflow, a similar issue on previous version and apparently the Android version have the something along the lines.

Thank you!

As v3.0 is still not in cocoapods and I cannot find the exact reference in the newer code but I think the issue is around the following place:

// in Charts/Core/ChartXAxisRenderer.swift
open func drawLabels(context: CGContext, pos: CGFloat, anchor: CGPoint) {
  ...
  for i in stride(from: self.minX, to: min(self.maxX + 1, xAxis.values.count), by: xAxis.axisLabelModulus)
    ...
  }
}

Basically this would simplify to the following:

for i in stride(from: 0, to: 50, by: 25)

Which would convert to following [0, 25] array missing therefore the last element ([50]).

I'm using: pod 'Charts', :git => 'https://github.com/danielgindi/Charts.git', :branch => 'Swift-3.0'

First you should try Chart 3.0, it has redesigned x axis rendering. Chart 2.2.5 will not have bug fix anymore.
For your question, you call stride(from: 0, to: 50, by: 25) where last value will be 0 + 25; It's your step issue. If you want to sure a middle value, I guess you have to override this method. Also You need to consider when you zooming, how do you display the middle value as well.
