How to use

Minimum requirements

• Action.Net version 9.2.28.1 or later;

Configuration

1. Insert the file "SPIN. ActionNet.View.Wpf.Charts.dll" in the WpfControls folder of the installation (typically

1. in "C:\Program Files (x86)\SPIN\Action.Net\an-x.x\WpfControls\") if it does not exist.

2. Open the project of the Action.Net where the control will be used;

3. In the "Draw" tab, choose the page where the control will be used;

4. In the

1. toolbar, choose the item "Insert Component";

2. When you open the component selection screen, select the BarAndSplineCustomChart control;

3. Insert the control

1. on the screen and scale it.

2. Select the control and

1. enter a Uid

1. for it. This is what will be used in the code-behind to pass the data to the

1. graph.

1. Configure the code in the screen code-behind:

Initially, you must it is necessary to access the control from your Uid. To take get a reference from the control to use it, use the following script:

SPIN.ActionNet.View.Wpf.Charts.BarAndSplineCustomChart barAndSplineCustomChart1 = 
		this.CurrentDisplay.GetControl("barAndSplineCustomChart1") as SPIN.ActionNet.View.Wpf.Charts.BarAndSplineCustomChart;
		
if(barAndSplineCustomChart1 != null){

//... code goes here

}

Then the data needs to be passed to the control. It has a function for passing data from a datatable to the control. Your subscription signature can be found checked below:

public void ApplyHistorianData(string tagName, DataTable histValues){}

Where:

tagName: refers to the search tag. This parameter is used for the Chart Header of the chart.

histValues: refers to a table whose format consists of the first column with values compatible with the type DateTime and the second column with values that are compatible with the types float or Double.

This function can be called as shown below:

string tagName = @"SE01\TR01\tag1.MED.MW";
DataTable result = GetHistorianMeasures(tagName);
if(result != null && result.Rows.Count > 0)
    barAndSplineCustomChart1.ChartControl.ApplyHistorianData(tagName, result);

This sample- specific application of the example used the Spin toolkit to search for measures for measurements of a given certain period (last 10 days). The full complete code for this application can be checked below:

using SPIN.ActionNet.View.Wpf.Charts;
	  
public void DisplayOpening()
{
}

public void DisplayIsOpen()
{
}

public void DisplayClosing()
{
}
 
////This method is only called on Dialog displays
public bool DialogOnOK()
{
	return true;
}

public DataTable GetHistorianMeasures(string tagName){
	DataTable result = null;
	
	try{
		DateTime startDate = DateTime.Now.AddDays(-10);		
		result = @Script.Class.CustomMeasures.GetMeasures(tagName, startDate, DateTime.Now, 10);
	}
	catch(Exception ex){
		@Info.Trace(ex.Message);
	}
	
	return result;
}

public void ButGetSampleData_Click(object sender, System.Windows.Input.InputEventArgs e)
{
	SPIN.ActionNet.View.Wpf.Charts.BarAndSplineCustomChart barAndSplineCustomChart1 = 
		this.CurrentDisplay.GetControl("barAndSplineCustomChart1") as SPIN.ActionNet.View.Wpf.Charts.BarAndSplineCustomChart;
		
	if(barAndSplineCustomChart1 != null){
		string tagName = @"SE01\TR01\tag1.MED.MW";
		DataTable result = GetHistorianMeasures(tagName);
		if(result != null && result.Rows.Count > 0)
			barAndSplineCustomChart1.ChartControl.ApplyHistorianData(tagName, result);		
	}
	
}

using SPIN.ActionNet.Biz.Toolkit.Reports;
using System.Threading.Tasks;

public DataTable GetMeasures(string tagName, DateTime startDate, DateTime endDate, int interval)
{
	List<string> tagNames = new List<string>();
	tagNames.Add(tagName);
	
	DataTable result = Measures.GetReport(tagNames,startDate, endDate, interval);
	
	return result;
}
