To expand or collapse the vertical size of chart subgraphs:
- Select the subgraph divider to size by clicking and holding the mouse button while the cursor is over the upper line between two subgraphs.
- With the mouse button depressed, ‘drag‘ the cursor to the desired new line location and release the mouse button.
- You must make sure the mouse cursor has changed to an up/down arrow before clicking on the upper divider line. If the cursor is still an arrow or a cross hair, the selection will not occur.
