Add NOV Chart control in WinForms at runtime
To get started and host NOV in your WinForms application, take a look at:
Getting Started with NOV in WinForms using only code
The following topic shows how to add a NOV Chart Widget (control) in
WinForms at runtime.
1. Reference the NOV Assemblies
Ensure that your application references the following NOV dlls:
Nevron.Nov.Presentation.dll - core NOV portable assembly;
Nevron.Nov.Host.WinBase.dll - base assembly for Windows presentation hosts (WinForm and WPF);
Nevron.Nov.Host.WinForm.dll - presentation host for Window Forms;
Nevron.Nov.Chart.dll - assembly for the NChartModule;
These assemblies are located in NOV installation folder: C:\Program Files (x86)\Nevron Software\Nevron Open Vision VERSION\Bin\Win
2. When initializing the NOV Application, make sure to create the Chart module
Open the Program.cs file and use the following code:
using Nevron.Nov;
using Nevron.Nov.Chart;
using Nevron.Nov.Windows.Forms;
using System;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
// Apply license for redistribution here. You can skip this code when evaluating NOV.
NLicenseManager.Instance.SetLicense(new NLicense("LICENSE KEY"));
// Install NOV
NModule[] modules = new NModule[] {
// TODO: Create modules here
NChartModule.Instance
};
NNovApplicationInstaller.Install(modules);
Application.Run(new Form1());
}
}
}
3. Create the Chart View and setup a Bar series
Open the Form1.cs file and use the following code to create the Chart:
using Nevron.Nov.Chart;
using Nevron.Nov.Graphics;
using Nevron.Nov.Windows.Forms;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
// clear all controls from the form
Controls.Clear();
// create chart
NChartView chartView = new NChartView();
chartView.Surface.CreatePredefinedChart(ENPredefinedChartType.Cartesian);
// configure chart title
chartView.Surface.Titles[0].Text = "Standard Bar";
// configure chart
NCartesianChart chart = (NCartesianChart)chartView.Surface.Charts[0];
chart.SetPredefinedCartesianAxes(ENPredefinedCartesianAxis.XOrdinalYLinear);
// add interlace stripe
NLinearScale linearScale = chart.Axes[ENCartesianAxis.PrimaryY].Scale as NLinearScale;
NScaleStrip strip = new NScaleStrip(new NColorFill(ENNamedColor.Beige), null, true, 0, 0, 1, 1);
strip.Interlaced = true;
linearScale.Strips.Add(strip);
// setup a bar series
NBarSeries bar = new NBarSeries();
bar.Name = "Bar Series";
bar.InflateMargins = true;
bar.UseXValues = false;
bar.Shadow = new NShadow(NColor.LightGray, 2, 2);
// add some data to the bar series
bar.LegendView.Mode = ENSeriesLegendMode.DataPoints;
bar.DataPoints.Add(new NBarDataPoint(18, "C++"));
bar.DataPoints.Add(new NBarDataPoint(15, "Ruby"));
bar.DataPoints.Add(new NBarDataPoint(21, "Python"));
bar.DataPoints.Add(new NBarDataPoint(23, "Java"));
bar.DataPoints.Add(new NBarDataPoint(27, "Javascript"));
bar.DataPoints.Add(new NBarDataPoint(29, "C#"));
bar.DataPoints.Add(new NBarDataPoint(26, "PHP"));
chart.Series.Add(bar);
// create NOV host
NNovWidgetHost<NChartView> host = new NNovWidgetHost<NChartView>(chartView);
host.Dock = DockStyle.Fill;
Controls.Add(host);
}
}
}
Run the application - it should display a simple form with a Bar Chart series.
Using Visual Basic .NET (VB.NET)
When you create a Visual Basic Windows Forms Application, reference the NOV Assemblies and use the following code in your Form1.vb:
Imports Nevron.Nov
Imports Nevron.Nov.Windows.Forms
Imports Nevron.Nov.Chart
Imports Nevron.Nov.Graphics
Public Class Form1
Inherits Form
Public Sub New()
InitializeComponent()
' clear all controls from the form
Controls.Clear()
' TODO: Apply license for redistribution here. You can skip this code when evaluating NOV.
NLicenseManager.Instance.SetLicense(New NLicense("LICENSE KEY"))
' Install Nevron Open Vision modules
Dim modules() As NModule = {NChartModule.Instance}
NNovApplicationInstaller.Install(modules)
' create chart
Dim chartView As New NChartView()
chartView.Surface.CreatePredefinedChart(ENPredefinedChartType.Cartesian)
' configure chart title
chartView.Surface.Titles(0).Text = "Standard Bar"
' configure chart
Dim chart As NCartesianChart = DirectCast(chartView.Surface.Charts(0), NCartesianChart)
chart.SetPredefinedCartesianAxes(ENPredefinedCartesianAxis.XOrdinalYLinear)
' add interlace stripe
Dim linearScale As NLinearScale = TryCast(chart.Axes(ENCartesianAxis.PrimaryY).Scale, NLinearScale)
Dim strip As New NScaleStrip(New NColorFill(ENNamedColor.Beige), Nothing, True, 0, 0, 1, 1)
strip.Interlaced = True
linearScale.Strips.Add(strip)
' setup a bar series
Dim bar As New NBarSeries()
bar.Name = "Bar Series"
bar.InflateMargins = True
bar.UseXValues = False
bar.Shadow = New NShadow(NColor.LightGray, 2, 2)
' add some data to the bar series
bar.LegendView.Mode = ENSeriesLegendMode.DataPoints
bar.DataPoints.Add(New NBarDataPoint(18, "C++"))
bar.DataPoints.Add(New NBarDataPoint(15, "Ruby"))
bar.DataPoints.Add(New NBarDataPoint(21, "Python"))
bar.DataPoints.Add(New NBarDataPoint(23, "Java"))
bar.DataPoints.Add(New NBarDataPoint(27, "Javascript"))
bar.DataPoints.Add(New NBarDataPoint(29, "C#"))
bar.DataPoints.Add(New NBarDataPoint(26, "PHP"))
chart.Series.Add(bar)
' Create the host widget
Dim host As New NNovWidgetHost(Of NChartView)(chartView)
host.Dock = DockStyle.Fill
' add the host in the form controls
Controls.Add(host)
End Sub
End Class
