Some space before chart bar

Question

My code has three bars and i need to make some space before them: it should start with some specific value, not 0;
What I have now
What I want to get (example)

Here is my code:

        var ch = new Chart();
        ch.Series.Clear();

        var cha = new ChartArea();
        ch.ChartAreas.Add(cha);

        var datePlanSeries = new Series {ChartType = SeriesChartType.Bar };
        var dateAgreedSeries = new Series { ChartType = SeriesChartType.Bar };
        var dateFactSeries = new Series { ChartType = SeriesChartType.Bar };

        datePlanSeries.Points.AddY(durationPlan);
        dateAgreedSeries.Points.AddY(durationAgreed);
        dateFactSeries.Points.AddY(durationFact);

        // And what should I add to each series to "move" it?

        ch.Series.Add(datePlanSeries);
        ch.Series.Add(dateAgreedSeries);
        ch.Series.Add(dateFactSeries);

Answer 1

There is a chart type called Range Bar. Each datapoint takes 2 Y-values, think from-Y and to-Y. So instead of:

var datePlanSeries = new Series {ChartType = SeriesChartType.Bar };

...

datePlanSeries.Points.AddY(durationPlan);

You use:

var datePlanSeries = new Series { ChartType = SeriesChartType.RangeBar };

...

datePlanSeries.Points.Add(1, 10); // from Y = 1, to Y = 10
