Matrix Chart View
When Matrix is selected as the Chart Type, the Toolbar appears like this:

- Select a Matrix chartable file in the Overlay Toolbox Charting tab.

- Matrix charts do not dynamically change, instead they show data that is dynamically accessible for viewing on the surface/volume in other viewing tabs.

- When viewing a CIFTI Parcel to parcel connectivity (.pconn.nii) file matrix, left click on a row to select a parcel (will be outlined with a horizontal box in the matrix). Parcel connectivity for the selected parcel will be displayed on Viewing Tabs that are showing the parcel connectivity file as a layer.

- A parcel can also be selected by clicking on a surface/volume in another Viewing Tab and the corresponding parcel row will be outlined in the matrix.

- When viewing a CIFTI Parcel Scalar (.pscalar.nii) file matrix, the y-axis rows are parcels and the x-axis columns are Map indices. When the map index is set in Overlay Toolbox: Layers for any non-Chart Viewing Tab, a vertical box appears in the matrix around the column for the selected map index.

- Chart Attributes: To adjust attributes of the matrix chart display, such as the cell width and cell height. The default setting fills the Viewing Area with the matrix cells. The Reset button resets the cell size to the default.

- Tab: These across Tab functions do not affect Chart View.
