Bar shapes are overlapped with other bars

[aravinth02]

When X set are continuous ordered value like the dataset provided below, each bars are getting overlapped as figure 1.

let xValues = [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2]
let yValues = [20.0, 4.0, 6.0, 3.0, 12.0, 16.0, 4.0, 18.0, 2.0, 4.0, 5.0, 4.0]

Figure 1:

But bars are not overlapped when the X values are as follows. See figure 2.
let xValues = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]

Figure 2:

Following snippet was used to draw the chart data

for i in 0..<xValues.count { let dataEntry = BarChartDataEntry(x: xValues[i], y: yValues[i]) dataEntries.append(dataEntry) } let chartDataSet = BarChartDataSet(values: dataEntries, label: "Units Sold") let chartData = BarChartData(dataSet: chartDataSet) barChartView?.data = chartData

Please help on how to resolve the bar overlapping on first test case.

how about you zoom in your first chart or change bar width?

I think you don't think about your data first
Your x value is [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2] which only has 0.1 interval, while your bar width is overwhelming - that seems like a overlap situation.
Either you change your bar width or make x axis has smaller granularity to give a try.
