Drawing / analysis tools can be interactively moved or re-sized with the mouse, as follows:
Click the left mouse button ONCE on the desired drawing tool.
This will "select" the tool, and you will see the "control points" highlighted on the tool.
While in this mode, you can move or re-size the tool as described below.
Move
Place the mouse pointer over any part of the drawing tool. When you see a four-way arrow cursor, you can click and drag the entire drawing tool to a new location.
Re-size
Place the mouse pointer over a control point of the drawing tool. When you see a two-way arrow cursor, you can click and drag the control point to graphically re-size the drawing tool.
NOTE: some tools cannot be re-sized, only moved (e.g. text box, trend line)
