Last bar not shown in bar graph

[Ruchita-Bora]

Here is the code i used to plot bar graph. But last orange bar is not visible. Tried to scroll but its not scrolling. I think gap between first blue bar and yaxis might be the issue. But not able to remove that gap. Can you help me with this?

       ChartXAxis xAxis = barChartView.XAxis;
        xAxis.DrawGridLinesEnabled = false;
        xAxis.LabelPosition = XAxisLabelPosition.Bottom;
        xAxis.CenterAxisLabelsEnabled = true;
        xAxis.SpaceMin = 0.0;
        xAxis.Granularity = 1;
        xAxis.AvoidFirstLastClippingEnabled = false;

        ChartYAxis rightAxis = barChartView.RightAxis;
        rightAxis.DrawGridLinesEnabled = false;
        rightAxis.DrawLabelsEnabled = false;
        rightAxis.DrawAxisLineEnabled = false;

        ChartLegend legend = barChartView.Legend;
        legend.Position = ChartLegendPosition.AboveChartCenter;

        var unitsSold1 = new double[] { 20.0, 4.0, 6.0, 3.0, 12.0 };
        var unitsSold2 = new double[] { 10.0, 8.0, 12.0, 6.0, 6.0 };

        List<BarChartDataEntry> dataEntries1 = new List<BarChartDataEntry>();
        List<BarChartDataEntry> dataEntries2 = new List<BarChartDataEntry>();

        for (int i = 0; i < unitsSold1.Length; i++)
        {
            BarChartDataEntry dataEntry1 = new BarChartDataEntry(i, unitsSold1[i]);
            dataEntries1.Add(dataEntry1);

            BarChartDataEntry dataEntry2 = new BarChartDataEntry(i, unitsSold2[i]);
            dataEntries2.Add(dataEntry2);
        }

        BarChartDataSet dataSet1 = new BarChartDataSet(dataEntries1.ToArray(), "Units Sold");
        dataSet1.Colors = new UIColor[] { ColorUtils.ColorWithHex(GlobalIOSColorConstants.DarkBlueColor) };
        dataSet1.AxisDependency = AxisDependency.Left;

        BarChartDataSet dataSet2 = new BarChartDataSet(dataEntries2.ToArray(), "Units Sold Last Year");
        dataSet2.Colors = new UIColor[] { ColorUtils.ColorWithHex(GlobalIOSColorConstants.BarOrangeColor) };
        dataSet2.AxisDependency = AxisDependency.Left;

        BarChartData barChartData = new BarChartData(new List<BarChartDataSet> { dataSet1, dataSet2 }.ToArray());
        barChartData.BarWidth = 0.25;
        barChartData.GroupBarsFromX(0, 0.42, 0.04);//group space, bar space
        barChartView.Data = barChartData;
        barChartView.HighlightPerTapEnabled = false;
        barChartView.HighlightPerDragEnabled = false;
        barChartView.DoubleTapToZoomEnabled = false;
        barChartView.PinchZoomEnabled = false;
        barChartView.SetScaleEnabled(false);
        barChartView.FitBars = true;

Hey @Ruchita-Bora,

I found two different solutions to this problem.

1) Set the SpaceMax to 1 xAxis.SpaceMax = 1;

2) Disable the property to center the x-axis labels and use use the SpaceMin as the starting point in GroupBarsFromX instead of setting it to zero. xAxis.CenterAxisLabelsEnabled = false; ... barChartView.GroupBarsFromX(-xAxis.SpaceMin, 0.42, 0.04);

With any of the two all bars will fit into the screen, but I'm not aware of the side effects for each one.

Btw, when picking the values for BarWidth, groupSpace and barSpace you need to keep the following math being true:

1f = (BarWidth + barSpace) * DATASET_COUNT + groupSpace
