Dot Plot, or Scatter Plot, is one of the charting options available in the Charts Panel. It graphs the values of two measurements on the x- and y-axes respectively for an object set. Each object within an object set is represented as a single dot.
To display the Dot plot, open the Charts Panel and select the Dot plot option 
from the Charts selection dropdown menu.
For detailed information about Dot Plots in general, please refer to the Wikipedia entry for Scatter Plot.

General usage
Select measurements
As with all charts, to select a measurement, hover over the measurement name until it turns red and then click to bring up a menu of the available measurements. Both the x- and y-axes measurement can be specified in this chart.
Select objects
Objects on the Dot Plot can be selected by dragging across the chart to create a box. You can also select objects by clicking on them individually and Shift + click to select multiple objects. Selected objects appear with red circles around the edge. Hovering over an individual data point will bring up the Track Number as well as the chart data for that point.
Magnify chart area
Magnifying the chart area can help with visualizing large datasets as it can be difficult to isolate the desired data point.
To activate the zoom tool, click on the Zoom Tool 
icon. You can drag the mouse cursor while holding the left mouse button to draw a box of the region to magnify. Repeat the magnification region until a desired level is reached. At this point, it is possible to switch to the Selection Cursor to select the data points of interest.
Change axis scale
To change the scale on any axis, click on the minimum or maximum value displayed and that value will appear in an editable window. Type in the value desired for the axis and hit Enter. Repeat this for other endpoint value as needed.
Context menu options
You can bring up the context menu by right-clicking anywhere in the Charts Panel. The context menu is specific to the Dot plot and can be used to adjust chart display options.
| Name | Description |
|---|---|
| Lock X Axis | Locks the x-axis at the current range displayed when this option is selected. Turn off this option to allow the chart to re-scale the x-axis for each time point to best fit the data |
| Lock Y Axis | Locks the y-axis at the current range displayed when this option is selected. Turn off this option to allow the chart to re-scale the y-axis for each time point to best fit the data |
| Update during play | With this option selected the Histogram will update to display the current frame when playing an image sequence. If deselected, the chart will update during single frame navigation, but will not update while playing an image sequence until the sequence is paused |
| Color mode | Determines how each data point on the chart will be colored; there are three options:
|
| Color for measures | Lets you select the color palette used when the Color by measure mode is selected |
| Assign color | This option brings up the Assign Color dialog. Here you can select a color to apply to all the selected objects. Different colors can be applied each time when selecting a different object or set of objects. This provides an easy way to visualize multiple defined populations |
| Reset color | Select this option to return to the default values for all objects being displayed |
