Select Text from the Insert menu to place custom text objects on the graph at any location. After clicking the Text button, the mouse pointer will turn to a cross-hair shape when it is passed over the graph. Clicking at any location on the graph places a graphic text box downward and to the right of the cursor location.
Click to activate this text object and drag it to a new position. Double-click the object to display the Graph Titles/Text dialog where the default text (i.e., Custom Text) can be replaced and customized.
Enter the desired text in the edit box; then use the buttons on the mini-formatting toolbar above the box to customize the text.
Click the OK button to place the text on the graph. Note that all custom text is initially inserted as static text (i.e., its position in the graph window is independent of the graph coordinates and scaling). It can be changed to Dynamic in the Text Object Properties dialog. To access this dialog, click the More button on the Graph Titles/Text dialog, then click the Text Object Properties button.
This dialog also provides access to customization options for other features such as frames, background patterns, and colors.
Note that you can also edit custom graph text on the Graph: Titles/Text options pane of the Graph Options graph customization dialog. If custom text needs to be aligned with other custom objects on the graph, consider using the Snap to Grid feature.
