I'm using the chart library for iOS from here: https://github.com/danielgindi/Charts
There's a good tutorial here: https://www.appcoda.com/ios-charts-api-tutorial/
The issue is labeling. The chart allows you to label the x coordinates using the init method in Swift: let lineChartData = LineChartData(xVals: dataPoints, dataSet: lineChartDataSet)
I don't see an equivalent in Objective C. There are plenty of Objective C examples on the GitHub site but they don't show you how to set x value labels. Any ideas?
