Fslview is able to display and draw graph plots of functional data. Load a functional data set as described in the image opening tutorial.
The displayed volume can be changed with the Volume SpinBox on the Image Toolbar. The functional data can also be animated by pressing the Movie button on the Image Toolbar. This automatically increments the Volume SpinBox and has the effect of showing all the volumes sequentially and looping back to the first volume when all volumes have been shown.
To view timeseries plots of the functional data select the image in the Overlay Listview and select from the View menu the Timeseries option.
A graph will be opened that shows the timeseries plot of the currently selected voxel. Clicking on the image with the Left mouse button will update the plot again with the timeseries of the new cursor position.
To permanantly keep the current plot on the graph press the Add series button at the top of the graph.(the icon is a plus sign) The timeseries plot will now remain on the graph. The cursor can now be used to add further plots to the graph while the selected plots remain.
The active plot is drawn in green and the inactive plots are drawn in blue. Clicking the mouse on an inactive plot will make the plot active and will move the image cursor to the plot's coordinates. Clicking on the Remove Series button (the icon is a minus sign) will cause the active plot to be removed from the graph.
