Thus, what we'd like to have is an interactive viewer - one where we can zoom in, pan and focus data in details, and possibly annotate points of interest, interactively and quickly the following quotes exemplify the typical expectations:Īnybody implement graph zoom with mouse wheel? - NI Discussion Forums I need to implement a zoom feature with the middle mouse wheel (like Google Maps, Google Earth, etc) on a CNiGraph. There may be several datasets ( channels) that need to be viewed simultaneously, in respect to the same abscissa (x-axis) ![]() ![]() There may be many (million or more) data points in a dataset ( channel) Of course, there are many data formats, and approaches to visualisation and analysis however, the data properties that are in focus here are:Įach data point is a real number (or in other words, a floating point number) Simulation results data from electronic circuit simulators like ngspice ĭata downloaded from digital oscilloscopes (see, for instance, agiload) Examples of this include:ĭata from statistical or mathematical analysis (using, say, R or scilab) A situation often occurs, where the user ends up with some sort of a large dataset that needs to be visualised and analysed. ![]()
