Add NOV Chart control in MonoMac project at runtime
To get started and host NOV in your Mac OS X (MonoMac) application, take a look at:
Getting Started with NOV in MonoMac project
The following topic shows how to add a NOV Chart Widget (control) in MonoMac project 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.MonoMac.dll - presentation host for MonoMac;
MonoMac.dll - make sure to reference the MonoMac.dll that comes with the NOV installation and remove the default one, which is created by Xamarin Studio;
Nevron.Nov.Chart.dll - assembly for the NChartModule;
You can reference the dlls directly from the System/Applications/NevronOpenVision.MonoMac.app/Contents/Bin folder or copy those dlls to a folder which is more convenient for referencing.
2. When initializing the NOV Application, make sure to create the Chart module
Open the Main.cs file and use the following code:
using System;
using Nevron.Nov;
using Nevron.Nov.Mac;
using Nevron.Nov.Chart;
#if UNIFIEDAPI
using Foundation;
using AppKit;
#else
using MonoMac.Foundation;
using MonoMac.AppKit;
#endif
namespace MonoMacApplication1
{
class MainClass
{
static void Main(string[] args)
{
NSApplication.Init();
NLicenseManager.Instance.SetLicense(new NLicense("LICENSE KEY"));
// install NOV
NModule[] modules = new NModule[]
{
// TODO: Create modules here
NChartModule.Instance
};
NNOVApplicationInstaller.Install(modules);
NSApplication.Main(args);
}
}
}
3. Create the Chart View and setup a Bar series
Open the MainWindow.cs file and use the following code to create the Chart:
using System;
using Nevron.Nov.Mac;
using Nevron.Nov.UI;
using Nevron.Nov;
using Nevron.Nov.Chart;
using Nevron.Nov.Graphics;
#if UNIFIEDAPI
using Foundation;
using AppKit;
#else
using MonoMac.Foundation;
using MonoMac.AppKit;
#endif
namespace MonoMacApplication1
{
public partial class MainWindow : NSWindow
{
#region Constructors
// Called when created from unmanaged code
public MainWindow(IntPtr handle)
: base(handle)
{
Initialize();
}
// Called when created directly from a XIB file
[Export("initWithCoder:")]
public MainWindow(NSCoder coder)
: base(coder)
{
Initialize();
}
// Shared initialization code
void Initialize()
{
NApplication.ApplyTheme(new NMacElCapitanTheme());
// 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
this.ContentView = new NNovWidgetHost(chartView);
}
#endregion
}
}
Run the application - it should display a simple Mac window with a Bar Chart series.
