Hi,
I have a Chart with dateTimes on the X Axis. I would like to print only the hour and minutes as it isn't readable otherwise (Original.PNG).
When I try to format it by using categoricalAxis on each series, it formats it correctly but creates an axis for each serie (Formatted.PNG).
I haven't found a way to keep only 1 Axis but with the formatted dateTimes.
I joined a copy of the important part of my code.

public FilesChart(){ InitializeComponent(); var db = new Context(); var result = db.FILESPROCESSEDs.Select(m => m.TYPE).Distinct(); List<String> listResult = result.ToList(); foreach (string type in listResult) { var source = db.FILESPROCESSEDs.Where(m => m.TYPE == type); BarSeries test = new BarSeries { DataSource = source.ToList(), ValueMember = "AMOUNT", CategoryMember = "DATETIME", IsVisibleInLegend = true, LegendTitle = type, CombineMode = Telerik.Charting.ChartSeriesCombineMode.Stack }; /*DateTimeCategoricalAxis categoricalAxis = new DateTimeCategoricalAxis(); categoricalAxis.DateTimeComponent = Telerik.Charting.DateTimeComponent.Hour; categoricalAxis.PlotMode = Telerik.Charting.AxisPlotMode.BetweenTicks; categoricalAxis.LabelFormat = "{0:HH:mm}"; test.HorizontalAxis = categoricalAxis;*/ radChartView1.Series.Add(test); } radChartView1.ShowLegend = true;}
You can create one axis and assign to all series:
public RadForm1(){ InitializeComponent(); DateTimeCategoricalAxis categoricalAxis = new DateTimeCategoricalAxis(); categoricalAxis.DateTimeComponent = Telerik.Charting.DateTimeComponent.Hour; categoricalAxis.PlotMode = Telerik.Charting.AxisPlotMode.BetweenTicks; categoricalAxis.LabelFormat = "{0:HH:mm}"; for (int i = 0; i < 10; i++) { var source = GetTable(); BarSeries test = new BarSeries { DataSource = source, ValueMember = "Value", CategoryMember = "Time", IsVisibleInLegend = true, LegendTitle = "Item " + i, CombineMode = Telerik.Charting.ChartSeriesCombineMode.Stack }; test.HorizontalAxis = categoricalAxis; radChartView1.Series.Add(test); } radChartView1.ShowLegend = true;}I hope this will be useful. Let me know if you have additional questions.

DateTimeComponent does not exist within DateTimeCategoricalAxis
You guys need more and better examples.
It's really hard to figure out how to use your components !
Hello, Don,
DateTimeComponent property does exist in the DateTimeCategoricalAxis. I have checked the provided code snippet from here and it is working correct on my side.
Can you please confirm whether you are using RadChartView from Telerik UI for WinForms suite, or you are referring to another product.
Please let me know if you have any other questions.
