TimeSeriesSweepPlot¶
Plot a multi-channel continuous time series.
This node is more efficient at handling high sampling rate data than the TimeSeriesPlot and can be used to step backwards/forwards through offline (non-streaming) data. For additional details, see the TimeSeriesPlot node. Version 1.0.1
Ports/Properties¶
data¶
Data to display.
stream¶
Name of stream to display. The first stream whose name starts with this string is displayed.
stream_name¶
scale¶
Data scale. Increasing this value will magnify the plot curves correspondingly.
buffer_duration¶
Duration of data to keep in the buffer. Only data in the buffer can be visualized.
time_range¶
Time range to display. This is the number of seconds of recent data that shall be plotted.
title¶
Title of the plot. This is the title of the plot window.
background_color¶
Background color. This is in hexadecimal (web) notation (#RRGGBB). For instance 00 is zero, 7F is half brightness, and FF is full brightness, so #FF00FF yields a color that is a mix of bright red and blue, i.e., bright purple).
line_color¶
Color of the graph curves. This is in hexadecimal (web) notation (#RRGGBB). For instance 00 is zero, 7F is half brightness, and FF is full brightness, so #FF00FF yields a color that is a mix of bright red and blue, i.e., bright purple).
zero_color¶
Color of the zero line. The zero line is a dim line that shows where zero would be for a given channel. This is in hexadecimal (web) notation (#RRGGBB). For instance 00 is zero, 7F is half brightness, and FF is full brightness, so #FF00FF yields a color that is a mix of bright red and blue, i.e., bright purple).
zeromean¶
Display data with mean corrected to zero. This makes sure that each channel is centered for better viewing. If this is disabled, your data may be outside the window, especially if you have not performed high-pass filtering on your signal. Enabling this may make the curves appear to shift up or down if their mean is not already zero. Disabled with streaming data; use a high-pass filter node in front of this node instead. zeromean is not recommended for streaming data. Instead, put a high pass filter in front of this node.
autoscale¶
Automatically scale channels to a standard scale. This makes sure that channels are rescaled such that they fit comfortably in the drawing area. All channels are rescaled by the same scale factor. Enabling this may make the curves appear to change scale suddenly, especially when large artifacts come into view or go out of view.
antialiased¶
Draw graphics antialiased. If enabled, the lines will appear less pixelated or 'jaggy', however, this can slow down plotting.
downsampled¶
Draw downsampled graphics. This will reduce the sampling rate (i.e., time resolution) of the data if the display time range or sampling rate is so high that one sample would be shorter than a pixel on the screen. This can speed up plotting in such cases. WARNING: some versions of the underyling graphics library crash with this option enabled, so using this is not recommended unless absolutely necessary. This will likely crash with streaming data if the update rate is high.
initial_dims¶
Initial position of the window on the monitor. This is given in pixels, and is formatted as [x, y, width, eight]. If x, y are set to 0 each, then the window will appear in the top left corner of the screen.
always_on_top¶
Window should be always on top. If this is enabled, then the window will not be occluded by other windows.
nans_as_zero¶
Show NaN values as zero.
set_breakpoint¶
Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.
metadata¶
User-definable meta-data associated with the node. Usually reserved for technical purposes.
