Configuring ILPanel

Interaction with ILPanel

ILPanel controls support mouse interaction out of the box. The type of interaction includes

1. Zoom in/out by single clicking on any ILPanel graph with left/right mouse button
2. Zoom in by region. The rectangular region gets defined by dragging a zoom rectangle with the mouse.
3. Rotating the whole ILPanel's scene. This is mostly usefull for 3D plots.

The type of interaction depends on the type of graps showing. If only 2D plots are shown, Rectangular zooming is used per default. For 3D plots clicking and dragging with the mouse will rotate the figure. However, the type of mouse interaction can also programmatically configured by the property ILPanel.InteractiveMode. This property is set every time a new graph is added to the panel.

All possible values of the InteractiveMode property:

• ZoomRectangle
• Rotating
• Selecting

Resetting the view

Double clicking with the mouse into the panel, the camera will be reset to rotation=0°, pitch=0°, distance=10. This view corresponds to the default view for 2D plots.

Magnetic rotation

In order to find 'even' rotation angles while rotating with the mouse, hold down the 'Alt' key. The angles of camera rotation will snap on multiple of Pi/4 for both, rotation and pitch.

Configuring visual styles

Colors for ILPanel background area is configured via the BackColor (derived from Control) and BackColorCube properties. In this image BackColor was set to Yellow and BackColorCube was set to SkyBlue.

The visibility of the cube's background area is controlled by the boolean BackgroundFilled property.
