[thierryH91200]

Hello
I am looking for beta testers for logarithmic axis implantation (see Issues # 109)
For tvos and ios programs and tell me if you are having problems
The demo is macOS
The link is https://github.com/thierryH91200/Charts-log
You will find some explanations

• Do not overload the axes
• LineChartView.xAxis.steps = [1.0])
• lineChartView.xAxis.stickEnabled = false or true for minors sticks
• The logarithmic scale is defined only for strictly positive values.
