Detailed Description

Widget for 2D-visualization of peak map and feature map data.

The widget is composed of two scroll bars, two AxisWidget and a Plot2DCanvas as central widget.

The example image shows Plot2DWidget displaying a peak layer and a feature layer.

slot that monitors the visible area changes and triggers the update of projections

◆ canvas()

Plot2DCanvas* canvas ( ) const

Returns a pointer to canvas object.

This method is overwritten for 1D, 2D, 3D to make the class specific members accessible.

The canvas object is set with the setCanvas_() method. This is usually done in the constructor.
