Add Diagram Text Button
The Add Text button on the Diagram window tool bar allows text of four types to be placed on the Diagram Window. The text options are simple text, formatted text, input variable, or output variable. The simple text option places an unformatted text item on the Diagram window. The formatted text option, available in the Professional license, allows a formatted text selection including embedded graphics to be placed on the Diagram window.
There are two ways to enter into this dialog window. Selecting Add Text from the Diagram window tool bar will create a new text item to be displayed on the Diagram window. Alternatively, double-clicking the left mouse button (or clicking the right mouse button) on an existing text item or a selected set of text items in the Diagram window will allow modifications to be made to the characteristics of that text item or set of text items.
If the Text radio button is chosen, a field will be provided to enter the text. International characters are accepted in the text edit box. A panel will appear to the right of the radio button with small buttons to facilitate entry of subscripts and superscripts and symbols, provided international characters are not in use. To enter a sub or superscript, select the text which is to be subscripted or superscripted and then click the sub or superscript button. The three additional buttons to the right of the sub and superscript buttons facilitate entry of lower or upper case Greek letters and useful symbols. The symbol entry buttons operate as follows. Press and hold the mouse button down on one of the three symbol buttons. A palette of symbols will be displayed to the right of the button. While holding the mouse button depressed, slide the mouse cursor to the symbol palette and position it over the symbol you wish to select. When the mouse button is released, that symbol will be added to the text item at the current insertion point.
If either the Input variable or Output variable radio buttons are selected, two check boxes will be visible with titles 'Include Variable Name', and 'Include Units'. If the 'Include Variable Name' box is checked, the EES variable name and an equal sign will be placed to the left of the edit box (for an input) or displayed numerical value (for an output). If the 'Include Units' box is checked, the units that have been specified for this variable will be displayed to the right of the edit box (input variable) or numerical value (output variable).
A New button is visible when a new text item is being developed. The New button accepts the current characteristics and places the current text item on the Diagram window, just as if the OK button were selected. It then allows a new text item to be defined. In this way many text items can be generated without having to close the Add Diagram Text dialog window. Clicking on the Cancel button, however, will remove all text items generated while this dialog window was open.
A series of text items in the Diagram Window can be selected in development mode (i.e., with the tool bar visible). A red dotted box will be displayed around each selected item. Pressing the right mouse button when more than one text item is selected will bring up a modified version of this dialog window in which the font, size, color, and style of the selected text items can be changed as a group. This dialog also provides a facility for aligning the selected text items. When it first appears, the dialog box displays the characteristics of the first selected text item. Any change made to a text characteristic in the dialog window will be applied to all selected text items. If a text characteristic, such as the font size, is not changed in the dialog window, then the font size of the selected text items will not be changed. In this way, it is possible to align text items or change just their font without affecting other characteristics such as the size or color.
