Plot Settings Dialog

The Plot Settings dialog enables the user to adjust certain plot settings.

Plot

Selecting Plot in the left-hand navigation pane displays the Plot section. The Plot section enables you to change various settings on how the data is displayed within the plot.

• Mode: Select the Mode of the plot.
• Min: Set the minimum value for the plot. The default value is to automatically determine the minimum.
• Max: Set the maximum value for the plot. The default value is to automatically determine the maximum.
• Refresh Rate (fps): Set the desired refresh rate in frames per second (fps) to perform smart thinning of the data. Enter 0 to disable smart thinning. The default value is 30 fps.
• Enable plot configure menu using mouse: This checkbox enables the NeXtMidas plot configure menu using the mouse.
• Enable quick access control widgets: This checkbox enables the quick access control widgets to change plot settings from the view. When enabled, Plot Port FFT has a quick control widget for adjusting the Fast Fourier Transform (FFT) number of averages directly in the view.

Output Port Name

Selecting the Output Port Name in the left-hand navigation pane displays the Output Port Settings dialog:

The Output Port Settings enable you to modify how the source is being displayed.

• The Show checkbox enables you to turn the plotting of individual data streams on and off.
• The Stream ID displays the Stream ID for each data stream in the plot.
• Clicking on Color brings up the Color Palette dialog, which enables you to select a color for the specified stream on the plot.
• Framesize: Enables you to override the displayed default frame size.
• The IF and RF radio buttons enable you to toggle between Intermediate Frequency (IF) and RF values for the x-axis on FFT plots.
• Center Freq: Enables you to override the center frequency value for RF plots. This field is grayed out for IF plots.

Expanding the Output Port Name in the left-hand navigation pane makes the Bulk Input/Output (BulkIO) and FFT settings available.

BulkIO

Selecting BULKIO in the left-hand navigation pane displays the BULKIO Settings dialog:

The BULKIO Settings dialog enables you to modify how the data is received via the CORBA Bulk Data.

• Connection ID: Displays the Connection ID of the current connection.
• Sample Rate: Enables you to set a custom sample rate to override the value in StreamSRI. Enter 0, or leave on AUTO, to use the value from StreamSRI.
• Remove on 'End of Stream': This checkbox enables you to select whether the stream is removed from the plot when an End of Stream (EOS) is received for the selected Stream ID.

• Blocking Option: This enables you to select a blocking option for pushPacket when the plot is not able to keep up with the data stream by selecting one of the radio buttons.

  • non-blocking - Do not block incoming data.
  • blocking - Block incoming data.
  • use SRI.blocking (default) - Set the blocking based on the StreamSRI.blocking field received from the pushSRI() call.

FFT

Selecting FFT in the left-hand navigation pane displays the FFT Settings dialog:

The FFT section enables you to change various settings on the FFT primitive.

• Num Averages: Enables you to change the number of averages in the FFT.
• Overlap: Enables you to change the overlap of the FFT.
• Sliding Num Averages: Enables you to change the sliding number averages of the FFT.
• Transform Size: Enables you to change the transform size of the FFT. For best results the entry should be a power of 2.
• Window Type: Enables you to change the window type of the FFT.
