Detailed Description
A dictionary for plot items.
QwtPlotDict organizes plot items in increasing z-order. If autoDelete() is enabled, all attached items will be deleted in the destructor of the dictionary. QwtPlotDict can be used to get access to all QwtPlotItem items - or all items of a specific type - that are currently on the plot.
