Technical Reference:Visualization Properties

Visualization properties are properties bound to visualization windows. Currently, the following visualization properties are defined:

Top, Left, Width, Height (number)

Position and size of the visualization window on the virtual desktop.

WindowTitle (string)

The visualization window's title.

MinValue, MaxValue (number)

The minimum and maximum expected signal value in Microvolts. This value is used to determine the signal's default scaling.

NumSamples (number)

The number of samples displayed in the visualization window.

ChannelGroupSize (number)

The number of subsequent channels that share a common signal baseline.

GraphType (number)

Polyline or Field2d. Polyline stands for the standard multi-channel signal view, while Field2d defines a two-dimensional field with color-encoded values.

ShowBaselines (boolean)

For a Polyline display, switches baselines on or off.

ChannelColors (list of hex values)

For a Polyline display, defines the list of colors to be used for drawing signals. The list is enclosed in curly braces as in { 0xff0000, 0x00ff00, 0x0000ff }.

SampleUnit (string)

The difference between two subsequent sample positions, given as a number followed by a unit, such as 1.4ms. This is used to display units on the x axis of the visualization window.

ChannelUnit (string)

If the channel dimension is a continuous variable, then this property gives the difference between two subsequent channels, as a number followed by unit, such as 2Hz. This is used to display units on the y axis of the visualization window, and currently only used with Field2d type graphs.

ValueUnit (string)

The value of one unit for the values displayed in a visualization window, such as 2muV. This property is used to display value units in Polyline type graphs.
