Charting
The Charting tab in the Overlay Toolbox contains controls for display of data graphs and matrices. The Active Tab must be in Chart View in order for this tab to be active (not grayed-out). For Data/Time Series chart type, Select checkboxes indicate whether file(s) will be charted when a brainordinate is identified (in another Viewing Tab).

- Loading shows loaded Data Series, Matrix, OR Time Series files to select for charting, depending on which Chart Type is selected in the Toolbar.

- For Data/Time Series chart type, Select checkboxes indicate whether file(s) will be charted when a brainordinate is identified (in another Viewing Tab).
- For Matrix chart type, select a loaded file from the dropdown (only one matrix file can be shown at a time). As in the Layers tab, wrench and colorbar settings buttons allow one to set the palette for the data displayed in the matrix and display a colorbar of the palette spectrum, respectively.

- History shows a list and line color for each identified vertex that has been charted. History is only active for Data/Time Series chart types.

- The chart displays a data value (y-axis) for each Map Index/unit of time (x-axis). The color of the selected brainordinate will match the color of (one of) the chart(s) graphed for that brainordinate.
- Each charted graph can be turned on/off of the display with the checkboxes. Most recent charts are listed at the top of the history.
- Show Average displays an averaged chart for all of the data displayed on the chart (charts graphed from different files will be averaged together). If displayed charts have differing numbers of data points, the average will have the same number of datapoints as the last graphed chart (listed at top).
- Show last selects the total number of charts to be displayed both in the Viewing Area and in the History. This setting is not retroactive and one may want to set this for a high value if multiple files are being charted at once. If a brainordinate "falls out" of the listed history/display, it will be displayed as the brainordinate ID symbol color set in Information Window > Properties.
