org.das2.graph.HugeScatterRenderer

HugeScatterRenderer This renderer can handle vector data sets with hundreds of thousands of points by histogramming the points and then creating a greyscale spectrogram of the histogram. The property "saturationHitCount" defines the number of pixel hits that will make the pixel black. This has been modified a lot over the years:

• connecting lines when the data is of timeseries,
• alternate modes are used when we zoom in closely,
• support for QDataSets and waveform scheme data,
• lone pixels are highlighted.
