I have used a number of Qt Charting libraries like QWT and QCustomPlot but finding them limited since they can’t be easily used for graphing large data. In my thesis, I stored my data in a QSqlDatabase and I need to view them in a graph for analysis. The problem with the existing libraries was that they cant be used to graph my data, reaching 10,000 points or more. Are there libraries existing that acts “more like” a Model/View that can graph large data (possibly with a scrollbar to show only part of the “BIG” graph interactively)?
