What are different methods of implementing graph?

As we have discussed, the two most common ways of implementing graphs are using adjacency matrices and using adjacency lists. We tend to prefer adjacency matrices when the graphs are dense, that is, when the number of edges is near the maximum possible number, which is n 2 n^2 n2 for a graph of n n n nodes.

An unlimited number of plot items can be displayed on its canvas. Plot items might be curves ( QwtPlotCurve ), markers ( QwtPlotMarker ), the grid ( QwtPlotGrid ), or anything else derived from QwtPlotItem. A plot can have up to four axes, with each plot item attached to an x- and a y axis.

What is the difference between Qt and Qwt?

Last release was in August 2012 (whereas last release of Qwt dates back to 2011). Subjectively, its interface seems more ‘aligned’ with Qt framework. Qwt, on the other hand, seems more mature and featureful.
