Chapter 2: WPF C# Walk-Through VS2008 VS2010

 ProEssentials charting WPF interfaces are used when creating stand-alone client-side EXEs to be distributed and ran on an end-users machine. This Wpf Charting Walk-through includes instructions for Visual Studio.Net in C#.


It is recommended that the namespace: Gigasoft.ProEssentials.Enums be included at the top of your source code files. In C#, use the using keyword:

using Gigasoft.ProEssentials.Enums;



The following information demonstrates how to create your first .NET WPF Charting ProEssentials implementation using the C# language in VS2010. It discusses using the Wpf interfaces to add interactive charting content to your EXEs. Other examples are provided within the product/evaluation. Click here for VS2015-VS2012.

1) New Project:

 Start Visual Studio.NET and create a new project targeting...

  •  Visual C#
  •  Windows
  •  WPF Application

 Accept the default name of [WpfApplication1].


wpf c# project

Note: Under the Project menu, select "Project Properties". From the Build tab, adjust the Platform Target setting to x86. This is necessary as the following ProEssentials assembly links to a native 32 bit DLL. This setting will allow the resulting exe to run on both 32 and 64 bit systems and provide the easiest deployment. For AnyCpu or native 64 bit targets, see our ReadMe.txt files in the folder ProEssentials9/DotNetAnyCpu.

2) When the new project opens, you will be presented the design view of "MainWindow.xaml and MainWindow.xaml.cs".

3) Installing WPF charting interfaces into Visual Studio.NET

 VS2008 / VS2010 Instructions

  • Under the Tools menu, select [Choose Toolbox Items...],
  • If not selected, left click the [WPF Components] tab,
  • Left click the [Browse...] button and find the file "Gigasoft.ProEssentialsWpf.dll" found in the DotNet32 subdirectory where you installed ProEssentials. By default, this is located at "C:\ProEssentials9\DotNet32\",
  • Select the file "Gigasoft.ProEssentialsWpf.dll" and close the [Open File] dialog,
  • The [Choose Toolbox Items] dialog should now show 5 highlighted controls: Pe3do, Pego, Pepco, Pepso, and Pesgo.
  • Close the dialog and the 5 new ProEssentials chart components will be at the bottom of the toolbox.
MainWindow.xaml.cs [Design]...

4) Right click the [PegoWpf] tool within the toolbox
and select [

Move your cursor within the text view of MainWindow.xaml.cs between the <Grid> and </Grid> tags
and right click and [Paste].

Adding ProEssentials WPF Charts to a Window...

This represents the default state of a ProEssentials Graph. The default state has one subset with four data points. In the course of constructing your own charts, you'll set the properties PeData.Subsets and PeData.Points which define the quantity of data your chart will hold. You'll then pass data via the PeData.Y[subset, point] two dimensional property array. The following section shows example code of passing data.

ProEssentials uses the terms Subsets and Points but you can think of these as Rows and Columns. Passing data is as simple as filling each Subset with Points worth of data.

5) After embedding the chart in your window, place the cursor within the PegoWpf tag and type "Name=" and provide a name for your chart "Pego1" and then type "Loaded=" and accept the default loaded event and right click and select Navigate to Event Handler. Your xaml should look like...

Adding WPF name and loaded event

With the cursor within the Pego1_Loaded code section, enter the following code into this section.

You can copy and paste, but hand-typing a few lines of this code will help familiarize yourself with the Gigasoft.ProEssentials namespace.  

Note: adding the following using declaration at the top of "MainWindow.xaml.cs" will shorten enumeration syntax.
using Gigasoft.ProEssentials.Enums;

Pego1.PeString.MainTitle = "Hello World";
Pego1.PeString.SubTitle = "";

Pego1.PeData.Subsets = 2;
Pego1.PeData.Points = 6;
Pego1.PeData.Y[0, 0] = 10; Pego1.PeData.Y[0, 1] = 30;
Pego1.PeData.Y[0, 2] = 20; Pego1.PeData.Y[0, 3] = 40;
Pego1.PeData.Y[0, 4] = 30; Pego1.PeData.Y[0, 5] = 50;
Pego1.PeData.Y[1, 0] = 15; Pego1.PeData.Y[1, 1] = 63;
Pego1.PeData.Y[1, 2] = 74; Pego1.PeData.Y[1, 3] = 54;
Pego1.PeData.Y[1, 4] = 25; Pego1.PeData.Y[1, 5] = 34;

Pego1.PeString.PointLabels[0] = "Jan";
Pego1.PeString.PointLabels[1] = "Feb";
Pego1.PeString.PointLabels[2] = "Mar";
Pego1.PeString.PointLabels[3] = "Apr";
Pego1.PeString.PointLabels[4] = "May";
Pego1.PeString.PointLabels[5] = "June";

Pego1.PeString.SubsetLabels[0] = "For .Net Framework";
Pego1.PeString.SubsetLabels[1] = "or MFC, ActiveX, VCL";
Pego1.PeString.YAxisLabel = "Simple Quality Rendering";

Pego1.PeColor.SubsetColors[0] = Color.FromArgb(60, 0, 180, 0);
Pego1.PeColor.SubsetColors[1] = Color.FromArgb(180, 0, 0, 130);

Pego1.PeColor.BitmapGradientMode = false;
Pego1.PeColor.QuickStyle = Gigasoft.ProEssentials.Enums.QuickStyle.LightShadow;
Pego1.PeTable.Show = Gigasoft.ProEssentials.Enums.GraphPlusTable.Both;
Pego1.PeData.Precision = Gigasoft.ProEssentials.Enums.DataPrecision.NoDecimals;
Pego1.PeFont.Label.Bold = true;
Pego1.PePlot.Method = Gigasoft.ProEssentials.Enums.GraphPlottingMethod.Bar;
Pego1.PePlot.Option.GradientBars = 8;
Pego1.PePlot.Option.BarGlassEffect = true;
Pego1.PeLegend.Location = Gigasoft.ProEssentials.Enums.LegendLocation.Left;
Pego1.PePlot.DataShadows = Gigasoft.ProEssentials.Enums.DataShadows.ThreeDimensional;
Pego1.PeFont.FontSize = Gigasoft.ProEssentials.Enums.FontSize.Large;

Pego1.PeConfigure.RenderEngine = Gigasoft.ProEssentials.Enums.RenderEngine.Direct2D;
Pego1.PeConfigure.AntiAliasGraphics = true;
Pego1.PeConfigure.AntiAliasText = true;
Pego1.PeUserInterface.HotSpot.Data = true;
// Pego1.Invalidate(); // optional help for real-time charts or certain update scenarios.
// Pego1.UpdateLayout(); // optional help for real-time charts or certain update scenarios.

Your project code should look similar to...

WPF C# vs2010 code window

WPF Charting events... Adding a DataHotSpot event...
C#.NET Chart event window for HotSpot event.

6) The code above enabled the DataHotSpot event, so we should place some appropriate code in the DataHotSpot event.

Left click the Pego Wpf chart control within visual designer to give it the focus.

From the main menu select [View] and [Properties Window] in case the property window is not showing.

Within the [Properties Window], click the [Events] icon.

Within the available events, double-click PeDataHotSpot

This opens the code view with cursor located at "Pego1_PeDataHotSpot".

Add the following code to the Pego1_PeDataHotSpot event.

System.Windows.MessageBox.Show("Subset " + e.SubsetIndex.ToString() +
", Point " + e.PointIndex.ToString() + " with a value of " +
Pego1.PeData.Y[e.SubsetIndex, e.PointIndex].ToString());

7) Save and run the project. Your project will show an image as follows. Move the mouse over chart and click a bar to trigger the DataHotSpot event.

This completes this WPF charting walkthrough. Please review the demo code and documentation that's installed with the eval/product. Demo projects can be accessed via shortcut... Start / All Programs / ProEssentials v9 Note that our main demo is replicated in native WPF C#, WinForm C#.NET, VC++ MFC and VB6 projects all accessible from the start menu. These are great for modifying an existing demo to test potential charting modifications before implementing within your applications. WPF Chart in Visual Studio 2010 with C# .Net language.
