Plot data from two signals
The Plot type parameter on the Plotting tab determines whether and how the block connects the points that it plots. For details, see Connections Among Points in Plots.
Signal Input Ports
|in||Signal containing data for Y axis. This signal must be an event-based signal.|
|x||Signal containing data for X axis. This signal must be an event-based signal.|
Signal Output Ports
|#c||Number of points the block has plotted.|
The initial output value is 0. This value is in effect from the start of the simulation until the first update by the block.
To open the block dialog box, click the Parameters toolbar button in the plot window.
The presentation format for the data. See Connections Among Points in Plots for details.
Selecting this option causes the plot window to open when you start the simulation. If you clear this box, you can open the plot window by double-clicking the block icon.
The interval shown on the X axis at the beginning of the simulation. The interval might change from this initial setting due to zooming, autoscaling, or the If X value is beyond limit setting.
Determines how the plot changes if one or more X values are not within the limits shown on the X axis. For details, see Vary Axis Limits Automatically.
The interval shown on the Y axis at the beginning of the simulation. The interval might change from this initial setting due to zooming, autoscaling, or the If Y value is beyond limit setting.
Determines how the plot changes if one or more Y values are not within the limits shown on the Y axis. For details, see Vary Axis Limits Automatically.
Toggles the grid on and off.
Text that appears as the title of the plot, above the axes.
Text that appears to the left of the vertical axis.
Text that appears below the horizontal axis.
A four-element vector of the form
[left bottom width

is the lower left corner of the display.
Displays the number of plotted points using an annotation in the plot window.
Unlimited to have the block
cache all data for future viewing,
cache a portion of the most recent data, and
avoid caching undisplayed data.
The number of data points the block caches, using the most recent
data. You see this field only if you set Store data when scope is closed to
These parameters determine whether the block produces data at signal output ports or omits those ports. For descriptions of the data and ports, see the preceding table, "Signal Output Ports".
Allows you to use the signal output port labeled #c.
