• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

ℹ Display lineChartView, with many lines. One line is one LineChartDataSet.

What did you expect to happen?

ℹ I expect that lineChartView not change height. For example if add 500 lineChartDataSets the height won't be change.

What happened instead?

ℹ When add more lineChartDataSets the height will be decrease.

Charts Environment

**Charts version/Branch/Commit Number:3.3.0
**Xcode version:10.3
**Swift version:5
**Platform(s) running Charts:iOS 12.3.1
**macOS version running Xcode:macOS Mojave 10.14.4

Demo Project

ℹ I download Charts-3.3.0, and add to function" setDataCount(_ count: Int, range: UInt32)",
in class LineChart2ViewController:

var dataSets = [LineChartDataSet]()
        var dataEntry = [ChartDataEntry]()
for _ in 0...500 {

            let interval = ChartDataEntry(x: Double(5), y: Double(5))
            dataEntry.append(interval)
            let dataSet = LineChartDataSet(entries: dataEntry, label: "")
            dataSets.append(dataSet)
        }
let data = LineChartData(dataSets: dataSets)

So you can launch app, then select Line Chart (Dual YAxis) and see same problem
