Working with Shape plots

This is the Shape plot for the Pyramidal cell model in neurondemo as it first appears on the screen. Its X axis is horizontal, the Y axis is vertical, and the Z axis is perpendicular to the page. Shape plots can be rotated, magnified or reduced, and translated.


  1. R click in the graph window and select 3D Rotate.
  2. Lift the mouse carefully off the pad, so that its cursor remains in the graph window.
  3. Press the L mouse button and hold it down.
  4. Use the A, X, and Z keys to examine the cell from three orthogonal directions.
    A top view down the Y axis
    X side view down the X axis, i.e. from the right
    Z side view down the Z axis (standard view seen above)
  5. Place the mouse back down on the pad, press the L mouse button, and run the mouse around on the pad to see the cell rotate wildly.
  6. Restore the standard view by pressing Z while holding the L mouse button down.
  7. Use ^X, ^Y, or ^Z (^ = Ctrl key) to rotate the cell in 10o increments around the X, Y, or Z axis.

Other operations

Use the secondary menu of the Shape plot window to

When you're done

be sure to set View/Section so you don't inadvertently cause other changes to the image.
