section:: Description
|
|
The link::Overviews/Methods#plot#plot method:: provides the ability to plot data in a GUI window. The method is implemented in the link::Classes/ArrayedCollection:: class but is also available for other classes for convenience, including link::Classes/Function::, link::Classes/Bus::, link::Classes/Env::, link::Classes/Buffer::, link::Classes/SoundFile::, link::Classes/Wavetable::.
|
|
|
|
method:: plot
|
|
All arguments are optional.
|
|
note::The arguments available vary from object to object. The below list is only for explanation of possible arguments.::
|
|
|
|
|
|
argument:: name
|
|
The name to be used as the GUI window title.
|
|
|
|
argument:: bounds
|
|
A link::Classes/Rect:: providing coordinates for the GUI location.
|
|
|
|
argument:: discrete
|
|
Plots are line-plots by default. Set this to code::true:: for bar charts.
|
|
|
|
argument:: numChannels
|
|
The number of interleaved channels that an array represents. For Buffers this argument is not available, since it's filled in automatically.
|
|
|
|
argument:: minval
|
|
Minimum value(s) for the display range. For a Buffer this defaults to code::-1:: but can be changed.
|
|
|
|
argument:: maxval
|
|
Maximum value(s) for the display range. For a Buffer this defaults to code::+1:: but can be changed.
|
|
|
|
argument:: separately
|
|
When finding the right display range in multi channel plots, do this together for all or keep them separate.
|
|
|
|
argument:: parent
|
|
By default the plot is placed in a new GUI window. This argument can be used to specify an existing GUI container to send the plot to.
|
|
|
|
argument:: labels
|
|
By default labels appear at the top left of the plot giving a data readout based on mouse position. Set this argument to code::false:: to prevent them appearing.
|
|
|
|
|
|
discussion::
|
|
If code::minval:: and/or code::maxval:: are set to code::nil:: (this is default, except for link::Classes/Buffer::s), they will be automatically calculated from the dataset minimum and/or maximum. For multi-channel data, code::minval:: and code::maxval:: may be arrays, specifying the range independently for each channel (including use of code::nil::, in which case the min/max will be calculated for the specific channel rather than for the overall dataset).
|
|
|
|
Hitting the strong::E-key:: on the keyboard when the window is focussed toggles the lock, and the window can be used to edit the data.
