Hi, I have few naive questions about Charts and DataVis modules.
1) As I understand DataVis module is mainly a 3d data visualization module while Charts is mainly a 1d data visualization module. Why not merging them to a unique data visualization module? In my lab scientists are interested in plotting 1d data in 3d or 2d plots. For example in space Physics people might be interested in plotting spacecraft electric potential vs time while looking particles spectrograms vs time. 2) The OpenGL acceleration in Charts module is really impressive, but I wonder why trying to draw big amount of points when the screen resolution is limited and why not integrating a king of downsampling algorithm as explained here: http://skemman.is/stream/get/1946/15343/37285/3/SS_MSthesis.pdf Or as implemented here: https://gitlab.com/DerManu/QCustomPlot/blob/master/src/plottables/plott able-graph.cpp#L1353 This would also reduce the memory usage of the graph. In this question I assume that OpenGL acceleration is used to plot bigger datasets I might be wrong.
