    I'm programming with VB.NET, I need help with the ChartView Y-axis value formatting.

    Can you let me know how to format the Y-axis with thousand separator instead of the exponential format and how to widen the Y axis if this is the issue.

    I attached a screenshot...

    Thanks and best regards,

    Hello Dominic,

    In order to format the Y-axis, you should access the LinearAxis and set its LabelFormat property to the custom format that you would like to display. By default, the AxisLabelElements are as wide as necessary to display the whole value. More information is available here. Below is an example:

    Public Sub New()
        Dim barSeries As BarSeries = New BarSeries()
        barSeries.Name = "Q1"
        barSeries.DataPoints.Add(New CategoricalDataPoint(17000000, DateTime.Now))
        barSeries.DataPoints.Add(New CategoricalDataPoint(128000000, DateTime.Now.AddDays(1)))
        barSeries.DataPoints.Add(New CategoricalDataPoint(143000000, DateTime.Now.AddDays(2)))
        barSeries.DataPoints.Add(New CategoricalDataPoint(111000000, DateTime.Now.AddDays(3)))
        barSeries.DataPoints.Add(New CategoricalDataPoint(118000000, DateTime.Now.AddDays(4)))
        Dim verticallAxis As LinearAxis = radChartView1.Axes.[Get](Of LinearAxis)(1)
        verticallAxis.LabelFitMode = AxisLabelFitMode.None
        verticallAxis.LabelFormat = "{0:#,###,###}"
    End Sub

    I hope this helps. Let me know if you need further assistance.
