Hi qsoft,

There is also another graph package which has all the graphing possibilities of ScatterDraw since it uses it's series class.
GraphDraw & GrahCtrl (it is in svn sandbox : svn://www.ultimatepp.org/upp/sandbox )

The main difference is that GraphDraw end GraphCtrl are built to be enhanced:

add specific axis management ( drawing, scaling, PropertiesDlg... )
add custom data over the plot ( exlusion zones for example)
Legend can be moved around and re-sized on the graph
add specific legend ( whatever you wan't )
In general add any sort of 'element' to the graph

It also has some other capacities that ScatterCtrl does not have :

Undo/Redo
native support of any number of axis (with individual/global move/zoom/FitToData )
plot image is cashed ==> the purpose is to avoid redraw when not necessary (if you have several charts with huge data on several tabs for instance .... you will appreciate this feature
fast draw : works by doing decimation of the data ==> the global shape/distribution of the data is kipped when moving/zooming the plot

This means you can achieve virtually any chart you need

The main drawback are the following:

no documentation yet (I'recently started filling up the gap slowly)
Complex code for the moment ( this is du to the use of a long inheritance tree that uses CRTP : the aim of this is to postpone some decisions the latter possible and when all is OK ==> kick out what's not needed ... so great simplification )

The following example shows a basic example of exclusion zones
