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.
