LineChart with combine charts

I want to draw various line graphs in this combinecharts but the visualization does not fit the line but only a dot at the start point.

// let data: CombinedChartData = [set1, set2, set3,sistolicLineChart]
let data = CombinedChartData()
data.scatterData = ScatterChartData(dataSets: [set1,set2,set3])
data.lineData = LineChartData(dataSets:lineDataSets)
data.setValueFont(.systemFont(ofSize: 7, weight: .light))
chartView.data = data

}

}

Start with ScatterTableViewCell.swift, especially setupChart(), setDataCount(), CombinedChartView, and the construction of CombinedChartData with lineData and scatterData. Reproduce the chart from the supplied code and inspect how the line datasets are rendered; done means the combined chart displays the line graphs rather than only a dot at the starting point.
