Visualize two-dimensional data Use the plot~ object to graph sets of data as points across a domain. The source of the data to be visualized may be a Max list, an MSP buffer~, or an audio signal. The number of plots may be changed with the @numplots attribute, and each of these "subplots" is addressed through a dedicated inlet. A variety of out-of-the-box configurations are provided as Max object prototypes. Cycling '74 Max MSP Audio Filter Dictionary MSP FFT MSP U/I Messages or Data for subplot 0 TEXT_HERE TEXT_HERE Set the first value of a subplot Set the first value of a subplot. Set the first value of a subplot Set the first value of a subplot. Data set to be plotted across the domain Data set to be plotted across the domain. The inlet at which the list is received determines which subplot graphs the data. If the list is larger than the number of points in the plot, then the list will be truncated. Define the domain for a subplot Define the domain for the subplot associated with the inlet at which the message is received. The number of actual points will not change, as that is set with the @numpoints attribute. This message sets the domain of numbers spanned by those points. For example, there may be 256 points representing a domain of [0.0, 1.0]. In this case the domain is essentially a label for the points. An optional third argument specifies 'linear' vs 'log' scaling of the domain. Define the color used for drawing a subplot Define the color used for drawing the subplot associated with the inlet at which the message is received. The order of the color components is red, green, blue, and alpha. Define a filter to be applied to the data set before it is graphed Defines a filter to be applied to the data set before it is graphed. There are currently two options available ('none' and 'atodb'). Define the style used to display lines in a subplot Define the style used to display lines in the subplot associated with the inlet at which the message is received. Options are 'linear', 'lines', 'curve', 'origin', or 'none'.

While 'lines' will display more quickly than 'linear', the 'linear' option will look better in some cases (usually when working with high thickness values). The difference between the display styles is related to how line segments are joined at the elbows: 'lines' does nothing, while the 'linear' option makes smooth connections. Define the style used displaying numbers in a subplot Define the style used displaying numbers in the subplot associated with the inlet at which the message is received. Options are 'above', 'below', 'center', or 'none'. Define the style used to display points in a subplot Define the style used to display points in the subplot associated with the inlet at which the message is received. Options are 'dot', 'circle', 'square', or 'none'. Define the range for a subplot Define the range for the subplot associated with the inlet at which the message is received. Values in the displayed data sets that are out of this range will be out of range of the plot drawing. Define the thickness of the lines for a subplot Define the thickness of the lines for the subplot associated with the inlet at which the message is received. A thickness of 1 indicates a 1 'pixel' linewidth. Define the points along the domain at which a vertical marker-line should be drawn for a subplot Define the points along the domain at which a vertical marker-line should be drawn for the subplot associated with the inlet at which the message is received. The points along the domain should be within the range specified by the 'definedomain' message. Define the value across the domain to serve as the origin for the plot Define the value across the domain to serve as the origin for the plot. Define the points along the range at which a horizontal marker-line should be drawn for a subplot Define the points along the range at which a horizontal marker-line should be drawn for the subplot associated with the inlet at which the message is received. The points along the range should be within the range specified by the 'definerange' message. Define the value within the range to serve as the origin for the plot Define the value within the range to serve as the origin for the plot. This will affect where lines originate when the line style is set to 'origin'. Define the labels for points along the domain of a subplot Defines the labels for points along the domain for the subplot associated with the inlet at which the message is received. For each point that you wish to be labeled, you must provide a float-symbol pair defining the location in the domain (as defined using the 'definedomain' message) and the label for that location. Define the labels for points along the range of a subplot Defines the labels for points along the range for the subplot associated with the inlet at which the message is received. For each point that you wish to be labeled, you must provide a float-symbol pair defining the location in the range (as defined using the 'definerange' message) and the label for that location. Configure a subplot Configure a subplot. The dictionary may contain the subplot's data, appearance, or both. Open an editor window for a subplot Open a dictionary editor window for a subplot. After making edits to the plot, simply close the window and the changes will take effect. Retrieve the state of a subplot Retrieve the state of a subplot. The returned dictionary will contain the subplot's complete state including both data and appearance configuration. Send mouse position and behavior to the outlet TEXT_HERE Signal whose samples will be collected and used as the dataset to display Signal whose samples will be collected and used as the dataset to display. The samples will be collected into blocks that are the same size as the numpoints attribute unless an audioframesize has been defined. Set a subplot to reference data in a named buffer~ object Set the subplot for the given inlet to reference the data in a named buffer~ object. If a second argument is given to this message, it will determine the channel within the buffer~ that should be displayed. Speed for display update Speed for display update when a plot~ is visualizing an audio signal. The drawing for such cases is driven by a clock operating at the specified number of frames per second. Frame size Number of samples collected from audio input to create a single frame of data. By default, audio signals will be visualized by collecting sample values until the number of points in the plot is full (audioframesize=0). Then all points will be updated and drawn. An alternate audioframesize value must be greater than the value of the numpoints attribute.

In some cases it is desirable to collect a larger set of samples and then visualize only a portion of those samples. To visualize the output of an FFT, for example, it is often desirable to only view either the first or second half of a frame because they are mirror images of each other. By setting the audioframesize, the number of points in @audioframesize will be collected, and only the first @numpoints will actually be drawn.

The object will grow/absorb inlets as needed. Each 'subplot' will be addressed through its dedicated inlet. Number of display points Sets the number of points to be displayed across the domain of all plots Left-hand (vertical) text TEXT_HERE Data-thinning behavior mode Data-thinning behavior when the size of the data set (number of points) exceeds the number of pixels available to display each point discretely. All points will be drawn, and will overlap as needed TEXT_HERE Number of points will be reduced according to thinto prior to drawing TEXT_HERE Thinning threshold The point at which the thinmode is invoked to begin reducing the data set. By default this attribute is set to a value of 10, meaning that once there are 10 points being drawn at the same pixel location on the screen the thinmode will be invoked. Data set reduction factor Factor by which the data set is reduced when the thinmode is invoked. By default the factor is 0.2, which results in 5 values being overlapped at a given pixel location. The 'mouse' message is sent together with normalized mouse coordinates and the mouse button state.
