manually set AxisX

[Mickael]

Hello,

It's possible to define manually maximum et minimum of AxisX.

Example :

Data : (2.12, 3.25, 4.25, 6.21, 1.25, 10.24)

I want minimum AxisX = 2 and maximum AxisX = 11 but i have to manually change it how ?

Hi,

If you are not using the default layout:

<telerik:RadChart UseDefaultLayout="False">
  <telerik:ChartArea>
    <telerik:ChartArea.AxisX>
      <telerik:AxisX AutoRange="False" MinValue="2" MaxValue="11" />
    </telerik:ChartArea.AxisX>
  </telerik:ChartArea>
</telerik:RadChart>

or if you are using the default layout:

<telerik:RadChart UseDefaultLayout="True">
  <telerik:RadChart.DefaultView>
    <telerik:ChartDefaultView>
      <telerik:ChartDefaultView.ChartArea>
        <telerik:ChartArea.AxisX>
          <telerik:AxisX AutoRange="False" MinValue="2" MaxValue="11" />
        </telerik:ChartArea.AxisX>
      </telerik:ChartDefaultView.ChartArea>
    </telerik:ChartDefaultView>
  </telerik:RadChart.DefaultView>
</telerik:RadChart>

Kind regards,
Dave.

Hello, 

But my data are not digital, but are datetime.

So how to put the MinValue and MaxValue because I do not?

Hi Mickael,

You can set custom Range for the Axis as David pointed out. Have in mind that if you are setting the DateTime values to XValue property of the Chart, the DateTime values have to be converted to their OLE Automation. For more information refer to our help topic.
In general you can set custom Range for the XAxis like this:

DateTime baseDate = DateTime.Today;
RadChart1.DefaultView.ChartArea.AxisX.AutoRange = false;
RadChart1.DefaultView.ChartArea.AxisX.AddRange(baseDate.ToOADate(), baseDate.AddDays(20).ToOADate(), 1);

Hello,

it's ok, but I like to have a defined interval (example: 12:00, 13:00, 14:00, ...)

I want my interval is 1h for example, without taking into account data.

How do I do?

Hi Mickael,

Since the data you have is DateTime, to be able to make the Step of the Axis 1 hour you should divide the hours by 24 like this for example:

RadChart1.DefaultView.ChartArea.AxisX.AddRange(new DateTime(2011, 5, 17, 12, 0, 0), new DateTime(2011, 5, 18, 0, 0, 0), 1/24d)
