For negative plotting the x-axis and actual x-axis is not overlapping

Question

What did I do?

Created a line chart project with linear mode. For that followed the demonstration code base https://github.com/danielgindi/Charts. So for plotting of positive x values and positive y values. But when I have plotted positive "X" values and negative and positive "Y" values then it seems the (0,0) co-ordinate of the plotted graph is not the same as actual (0,0) co-ordinate. Plotted the chart as follows:

ChartDataEntry(x: 0.0, y: 8.0) ChartDataEntry(x: 1.0, y: 42.0) (ChartDataEntry(x: 3.0, y: 0.0) (ChartDataEntry(x: 7.0, y: 45.0) (ChartDataEntry(x: 8.0, y: 28.0) (ChartDataEntry(x: 10.0, y: 0.0)

What did I expect to happen?

Expected that the limit line at 0 x-axis and the actual plot 0 x-axis has to be same.

What happened instead?

There is a 12-14 pixels gap between the 0 x-axis and the actual plot 0 x-axis. Please find the below screen shot :

Could you please help if anybody tried the negative line chart plotting using this danielgindi/Charts SDK. Thank you in advance for your help. Charts version/Branch/Commit Number: : v4.1.0 Xcode version: 13.0 Swift version: Swift 5

Tried the above explained plot using Chart SDK. Added the limit lines as well:

let ll1 = ChartLimitLine(limit: 100, label: "")
        ll1.lineWidth = 0.3
        ll1.lineColor = .gray
        ll1.lineDashLengths = [0, 0]
        ll1.labelPosition = .rightBottom
        ll1.valueFont = .systemFont(ofSize: 5)

        let ll2 = ChartLimitLine(limit: 0, label: "")
        ll2.lineWidth = 0.3
        ll2.lineColor = .gray
        ll2.lineDashLengths = [0, 0]
        ll2.labelPosition = .rightTop
        ll2.valueFont = .systemFont(ofSize: 5)
        
        let ll3 = ChartLimitLine(limit: -100, label: "Lower Limit")
        ll3.lineWidth = 0.3
        ll3.lineColor = .gray
        ll3.lineDashLengths = [0, 0]
        ll3.labelPosition = .rightTop
        ll3.valueFont = .systemFont(ofSize: 5)

DataSet default to depend on left axis, you need to change the axisDependency to right axis

dataset.axisDependency = YAxis.AxisDependency.right
