Detailed Description

A scatter plot matrix (SPLOM) widget.

Multidimensional data points are shown using a grid of 2D scatter plots for each pair of dimensions.
Each plot is interactive and user-transformations such as scaling and translating
are possible using mouse wheel and right-button dragging correspondingly.
When 'R' key is pressed all the transformations are reset to default.
The user can also hover over points of any plot, to see a popup with detailed information about the point.
When hovering over a point, it will be highlighted in all plots to allow interactive exploration.
Any parameter of the data can be color-coded using a lookup table.
Any scatter plot from an upper matrix triangle can be maximized by clicking a button in the upper-right corner.
The maximized plot can be minimized by using a button in upper-right corner.
Inherits Q[Open]GLWidget,manages scatter plots internally.
Some customization options are available via the public settings member.

Usage:
- Create iAQSPLOM
- add to a window/widget, make visible
- set some data (using one of the setData methods)
- set a lookup table for dot colors (setLookupTable)
- (optional:) set the parameter visibility (by default, all parameters are visible
- (optional:)

Example (visibleWidget is some widget, currently shown, with a layout):
    iAQSplom* splom = new iAQSplom();
    visibleWidget->layout()->addWidget(splom);

... you might want enable Qt to process a paint event here, to make sure the OpenGL context is created QSharedPoiner<iASPLOMData> splomData = createSPLOMDataSomehow(); splom->setData(splomData); iALookupTable lut; we assume here you want all points colored in a middle gray; we set up a color lookoup table over all values of column 0, and set the same color for the whole range if you want to color the dots by an actual column value, adapt this to your own needs! lut.setRange( splomData->paramRange(0) ); lut.allocate(2); QColor CustomDotColor(128, 128, 128) lut.setColor( 0, CustomDotColor ); lut.setColor( 1, CustomDotColor ); splom->setLookupTable( lut, 0 );
