Dashboard chart - Introduce the capability to specify Min/Max axis range values

created 10 years ago (modified 10 years ago)

Hello,

I built & run the application DX_Sample.zip in
https://www.devexpress.com/Support/Center/Question/Details/T164795

But the application does not scale the axis of the chart.

In addition to this, assuming that the application works as promised, Is there a way to get the axis range values from the layout xml file. Specifically, I would like to embed Axes Range Min. and Max. values into the xml. When, loading the Dashboard to a Dashboard Viewer, the chart should have the scale between embedded values in xml. Can I utilize Dashboard.UserData property for this purpose?

I modified the code as below. But still have no result.

C#
private void simpleButton1_Click(object sender, EventArgs e)  
{  
    DashboardChartControl chart = (DashboardChartControl)((IUnderlyingControlProvider)dashboardDesigner1).GetUnderlyingControl(dashboardDesigner1.Dashboard.Items[0].ComponentName);  
    XYDiagram diagram = (XYDiagram)chart.Diagram;  
    diagram.AxisY.VisualRange.Auto = false;  
    diagram.AxisY.VisualRange.SetMinMaxValues(90, 105);  
}

Hello Atilla,
I have checked changes made in version 14.2 and modified your code in the following manner:

C#
private void simpleButton1_Click(object sender, EventArgs e)  
{  
    ChartControl chartControl = (ChartControl)((IUnderlyingControlProvider)dashboardViewer1).GetUnderlyingControl("chartDashboardItem1");  
    SecondaryAxisY secondaryAxesY = ((XYDiagram)chartControl.Diagram).SecondaryAxesY[0];  
    secondaryAxesY.VisualRange.Auto = false;  
    secondaryAxesY.VisualRange.SetMinMaxValues(Convert.ToDouble(0.4), Convert.ToDouble(0.7));  
}

Please look at the attached sample. Yes, you can use the Dashboard.UserData property to save custom data in the dashboard. I am going to share this solution in the Dashboard chart - Introduce the capability to specify Min/Max axis range values thread as well.
