Using ILFigure

Whenever a visual output is needed, but no control surface is available, one can use ILFigure to create a plotting dialog. ILFigure therefore enables the creation of plots for console applications also.

Basically, ILFigure is a Windows.Forms.Form, containing an ILSubfigure as only control.

Creation of ILFigure forms is simple:

• include needed references (ILNumerics.Drawing.dll)
• include needed namespaces
• create and configure an instance of ILFigure
• display the ILFigure as regular form or as dialog

ILFigure example

The following code creates an ILFigure dialog from within a console application, showing some example data as imagesc graph. In order to compile it with Visual Studio 2005, create a new Console Application project, include both references (ILNumerics.Drawing.dll and ILNumerics.Net.dll) and replace the content of the only class file with that code:

using ILNumerics; 
using ILNumerics.Drawing; 
using ILNumerics.Drawing.Graphs; 
using ILNumerics.Drawing.Controls; 
using ILNumerics.BuiltInFunctions; 
using System.Windows.Forms; 

namespace Example8 {
class Program {
    static void Main(string[] args) {
        ILArray<double> tmp = SampleData.CreateData(120,120,1); 
        ILFigure fig = new ILFigure(); 
        fig.ActiveSubfigure.Panel.Graphs.AddImageSCGraph(tmp);
        ILPanel panel = fig.ActiveSubfigure.Panel; 
        (panel.Graphs[0] as ILImageSCGraph).Wireframe.Visible = false; 
        fig.ShowDialog(); 
    }
    public class SampleData : ILNumerics.Algorithms.ILAlgorithm {
        public static ILArray<double> CreateData (int rows, int cols, float den) {
            ILArray<double> x = repmat(linspace(-pi*den,pi*den,rows).T,1,cols); 
            ILArray<double> y = repmat(linspace(-pi*den,pi*den,rows),rows,1); 
            ILArray<double> tmp = cos(x*y) * 2;
            return tmp; 
        }
    }
}
}

Notice the access of the panel contained in the figure: fig.ActiveSubfigure.Panel. This gives access to the panel, which is contained in the (currently 'only one') subfigure for the ILFigure.
