Detailed Description

Widget class that generates time and frequency domain plots and 3D plots for the snBlocks.

Since threads must never access widgets that were created in the main thread, snWidget serves as agent for plotting to windows created by the main thread. Threads can request time and frequency domain plots or 3D plots from it and main() can request snWidget to replot all plots. The snBlocks directly write to snWidget's member data to spped up the plotting process. A snBlock can request the following plot types from snWidget:

• TPlots: Plots for time and frequency domain plots. snBlock writes data to snWidget->X and Y.
  • TIPlot: plot inphase component
  • TQPlot: plot quadrature component
  • TIQPlot: plot inphase and quadrature component into one plot
  • TSMPlot: plot spectrum magnitude (SM) component
  • TSAPlot: plot spectrum angle (SA) component
• SPlot: Plot 3D plot. snBlock writes data to snWidget->SXY.
• XPlot:
• TLabel: Provides simple text label.
