Hello, 

If you want to change the font only for a single label in the axis, you can access the respective AxisLabelElement via the LinearAxis.Children collection and set the desired Font as it is demonstrated in the code snippet below:

ScatterSeries scatterSeries = new ScatterSeries();
scatterSeries.Name = "";
scatterSeries.DataPoints.Add(new ScatterDataPoint(15, 19));
scatterSeries.DataPoints.Add(new ScatterDataPoint(18, 10));
scatterSeries.DataPoints.Add(new ScatterDataPoint(13, 15));
scatterSeries.DataPoints.Add(new ScatterDataPoint(10, 8));
scatterSeries.DataPoints.Add(new ScatterDataPoint(5, 12));
scatterSeries.PointSize = new SizeF(8, 8);
this.radChartView1.Series.Add(scatterSeries);

LinearAxis horizontalAxis = radChartView1.Axes.Get<LinearAxis>(0);
AxisLabelElement axisLabel = horizontalAxis.Children[1] as AxisLabelElement;
axisLabel.Font = new Font("Arial",12f, FontStyle.Italic);

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

but i want this

Hello,  

According to the provided screenshot, it seems that you want to change the font for the title of the entire RadChartView which is located at the bottom. You can use the following code snippet:

this.radChartView1.ShowTitle = true;
this.radChartView1.Title = "Sample title";
this.radChartView1.ChartElement.TitlePosition = TitlePosition.Bottom;
this.radChartView1.ChartElement.TitleElement.TextAlignment = ContentAlignment.MiddleCenter;
this.radChartView1.ChartElement.TitleElement.Font = new Font("Arial",12f, FontStyle.Italic);

I hope this information helps.

Hello,   

Thank you for specifying that you need to change the font of the horizontal axis. It was not easy to understand what is the exact requirement that you have from the previous replies. 

In order to achieve it, you can use the following code snippet: 

LinearAxis horizontalAxis = radChartView1.Axes.Get<LinearAxis>(0);
horizontalAxis.Title = "Axis' title";
horizontalAxis.Font= new Font("Arial",12f, FontStyle.Italic);

I hope this information helps.

I encountered an error message

[asghar]

hi

at the end,i did it

radChart1.Axes[0].TitleElement.Font= new Font("Arial", 15, FontStyle.Bold);

[asghar]

Finally, I did it

radChart1.Axes[0].TitleElement.Font= new Font("Arial, 15, FontStyle.Bold);

[Brandon]

I converted:

LinearAxis horizontalAxis = radChartView1.Axes.Get<LinearAxis>(0);
horizontalAxis.Title = "Axis' title";
horizontalAxis.Font= new Font("Arial",12f, FontStyle.Italic);

 

to:

Dim HA As LinearAxis = DashBoard.chtNewDayAvg.Axes.[Get](Of LinearAxis)(0)
Dim AL As AxisLabelElement = DirectCast(HA.Children(1), AxisLabelElement)
AL.ForeColor = Color.White

If RecHasData(Counts) Then
    'Play with the 30 day rolling avg.
    DashBoard.chtNewDayAvg.ShowLegend = False
    DashBoard.chtNewDayAvg.Series(0).DataPoints.Clear()
    'Not sure about the areas

    For I As Integer = 0 To UB(Counts)

        Dim Statuses As New List(Of String)
        Statuses.AddRange(Split(GetFromSet(Counts, 1, I), Separator2))

        Dim AssetsDown As Integer = 0
        For II As Integer = 0 To Statuses.Count - 1
            Dim Val As Integer
            Integer.TryParse(Statuses(II).Split(Separator)(AssetTypeSlot), Val)
            Select Case Statuses(II).Split(Separator)(0)
                Case "Down"
                    AssetsDown += Val : If Val > MaxDwn Then MaxDwn = Val
                Case "Repairing"
                    AssetsDown += Val : If Val > MaxDwn Then MaxDwn = Val
            End Select
        Next

        Dim DT As String = FMDB(GetFromSet(Counts, 0, I), False).ToShortDateString
        Dim P As New CategoricalDataPoint(AssetsDown, DT)
        P.Label = AssetsDown
        DashBoard.chtNewDayAvg.Series(0).DataPoints.Add(P)

    Next

    Dim HA As LinearAxis = DashBoard.chtNewDayAvg.Axes.[Get](Of LinearAxis)(0)
    Dim AL As AxisLabelElement = DirectCast(HA.Children(0), AxisLabelElement)
    AL.ForeColor = Color.White

End If

HA is nothing, so I get an Object Reference error on the second line where it tries to get the children.

You example was to adjust the font for a specific horizontal label.  I just want to set the ForeColor for all of them.  This is the code I'm using to populate the Graph with data.

 

[Brandon]

Nevermind.  Set the forecolor using this:

DashBoard.chtNewDayAvg.Series(0).Axes(0).ForeColor = Color.White

Hello,         
 
I am glad that the problem you were facing is now resolved. Feel free to access the axis after RadChartView is populated with points. Then, it is not supposed to be null.

Note that if you want to customize the labels in the axis, you can access the respective AxisLabelElement via the LinearAxis.Children collection apply the desired style.
