The rectangle is a non-analytical drawing object used to highlight or bring attention to a group of bars or a particular section in a chart.
When a rectangle is drawn, four "grab bars" are placed around the object. To resize the rectangle, click on the object to select it, position the cursor on any of the grab bars, and drag it to the desired size.
To move the rectangle, position the cursor in its center (the cursor changes to a hand). You can now drag it to a new position on the chart.
You can change the fill color of the rectangle by right clicking inside the rectangle and selecting Object Properties.
Click the Color box to choose a color from the drop-down list. Click Apply. Click OK.
