Organization Charts, Flow Diagrams, and More
Drawing An Organization Chart
Even though Draw does not have an organization chart toolbar, you can draw these charts by drawing rectangles and connector lines (see Figure 1). You can indicate hierarchies by using a color progression from dark to light tones. Be sure your color choices maintain a good contrast between text color and background so that you can easily read the printed diagram.
Before you begin, prepare a setup page or draft, with snap lines, to assist in drawing the various hierarchies, responsibility paths, and typical boxes that you will use in drawing the chart.
Place and dimension the individual boxes according to the size of the overall chart. The exact size (particularly width), position, and color will be fixed later. It is sometimes easier to draw only one box per level; later you can copy and paste this box and then move the copies to the desired positions. Using styles can also be helpful; see the relevant section in Chapter 4 (Changing Object Attributes).
You can also select one or more boxes and use Edit > Duplicate to make copies (see Figure 3). The spacing of the duplicated objects relative to the original can be controlled using the placement fields for the X and Y axes. Note that positive values for X and Y are to the right and downwards from the original object.
Which replication technique you use is up to you. The draft for the example in this chapter should look similar to that in Figure 4.
The next step is to add text to the boxes. It is easiest to insert it as a text element within the box as described in Chapter 2 (Drawing Basic Shapes). Activate the icon on the Options toolbar and then doubleclick the box to enter text into it. Alternatively, select the box and press F2. You should then see a blinking cursor in the box and the Text Formatting toolbar should be visible.
Set the text formatting and type the text. Depending on the length and format of the text, you may need to adjust the size of the box and the spacing to neighboring boxes or else change the formatting of the text to fit the box. Adjustments can be made initially with the mouse and then fine-tuned with the Position and Size dialog.
Now set up the fill colors and save the drawing. The connections between the boxes are not drawn with ordinary lines but with Draw’s connectors. How to draw these connectors and add text to them is described below in "Editing glue points".
You can use dynamic text frames instead of boxes. These have the advantage of automatic line breaks. Figure 5 shows the sequence of text input into a frame, adding borders, and setting the background color.
Drawing A Flow Diagram
The easiest way to draw a flowchart is to follow the same setup procedure as for organization charts. Select the symbols from the toolbar and drag them into position as described in Chapter 2 (Drawing Basic Shapes). See Figure 7 for an example of a typical flowchart.
The individual symbols must be exactly positioned if the connectors joining them are to form a vertical line. The midpoints of all the symbols that lie in a vertical straight line should have the same X coordinate and those on the same level on a horizontal line should have the same Y coordinate.
Select the shapes that are to lie in a vertical straight line and center them with Modify > Alignment > Centered. For those on a horizontal line, select the shapes and center them with Modify > Alignment > Center. You can also set snap lines if you need several vertical lines.
After adding text and setting the fill color, you can join individual symbols together and add text to the connectors. This technique is described in the next section.
Glue Points and Connectors
These elements were briefly introduced in Chapter 2 (Drawing Basic Shapes). This section describes how to use them.
Connectors are lines or arrows whose ends automatically dock to a connection or glue point on an object. Connectors are particularly useful when drawing organization charts, flow diagrams, and mindmaps. The connecting lines between the symbols remain intact even when the latter are moved or rearranged.
The connector toolbar
If the type of connector you want is not shown, click on the  in the Connectors toolbar. In the list that appears, click on Visible buttons (Figure 9) to open a menu from which you can activate additional types of connector.
Connector types fall into four groups:
- Standard connectors – the line segments run vertically and horizontally. All angles are right angles. The connector does not bend around the objects it binds.
- Line connectors – consist of a line segment and two smaller horizontal or vertical segments at the ends.
- Straight connectors – consist of a single line.
- Curved connectors – are based on Bézier curves, as described in Chapter 10 (Advanced Draw Techniques).
You can modify all the connector types from the context menu. Select Connector to change from one connector type to another (as well as some other properties). With the Line dialog you can change the appearance of the line (color, arrow style, and line style) but not the connector type.
Drawing Connectors - basics
When you choose a connector from the toolbar, the mouse pointer changes to . As you move the cursor over an object, the available connection points (also referred to as glue points) become visible. To connect two shapes, move the mouse cursor over a glue point, click and hold down the left mouse button to establish the first point, and then drag the mouse cursor (left button still pressed) to the other glue point and release the mouse button. The ends of the line are now docked and the connection is established (see Figure 10).
You can also attach the beginning or the end of a connector to the middle of an object. This is useful when the final position of the object is not yet determined. When you move the object, Draw automatically selects the optimal location for the connector ends (see Figure 11).
As with all other objects, connectors have one or more control points to simplify the construction of the drawing. You can use these points to change the shape, length, and proportions of the connector line (see Figure 12).
To remove a connector from an object, either move the end of the connector away from the glue point of the object or simply delete the connector entirely.
Editing glue points
The following briefly describes the function of each button on this toolbar.
Use this button to insert a new glue point. Draw a new object. If the object is filled, you can place a glue point anywhere inside the object or on its frame. With unfilled objects you can place a glue point only on the outside frame but, after inserting it, you can then drag it inside the object. Activate the Glue Points icon on the Drawing toolbar.
The glue points that you add remain visible as long as the Glue Points icon is active. They appear as small blue crosses. A selected glue point has a gray square behind the cross. You can move a selected glue point with the mouse or delete it with the Del key.
In the left-hand drawing below is a glue point in the circle with a left entry and one in the square with a right entry. The effect of this when adding a connector between the two glue points is shown in the right-hand drawing..
If you are in glue point editing mode and you add another direction to a glue point (for example by activating the button), Draw tries to optimize the length of the connector. For the example above, the connection inside the circle would change as shown below.
If the Glue Point Relative button is deactivated, the remaining buttons on the toolbar, previously grayed out, become active. With these buttons you can decide how a glue point will be placed when the size of the object is changed.
These buttons determine how the horizontal position of a glue point changes when you resize the object containing the glue point. You can choose whether the distance of the glue point to the left edge of the object, to a vertical line through the middle, or to the right edge of the object remains fixed when you change the size of the object. If the width of the object becomes less than that distance, the glue point is attached to the object frame.
The following example shows what happens when an object’s width is changed and the glue point is set to be a fixed distance to the left frame.
Adding text to connectors
To add text to a connector, double-click the connector. The end and control points become active and the familiar flashing text cursor appears (the cursor position is determined by the last used setting). The Text Formatting toolbar also appears (under the menu bar). Use this toolbar to set the text properties; you can directly input the text.
If you draw a connector and then click on it, only the end points and control points become active. In spite of this, a connector has its own object frame—in this case an invisible one. You can picture it easily by imagining a rectangle enclosing the start and end points of the connector (Figure 14).
When you add text to a connector, the location of the text is referenced to this rectangle. The exact position of the text can be set in the Text dialog (Figure 15). This dialog appears when you double-click on text and then choose Text from the pop-up menu or when you single-click on the connector and select Format > Text from the menu bar.
Take particular note of the Spacing to borders and Text anchor sections in the Text dialog. In the Text anchor section you can see the possible locations for the text. In the above example the text is anchored at the top left. In the Spacing to borders section at the lower left, negative values of spacing will position the text outside the frame.
Adjusting text to suit the connecting line
If you want the text to follow the slope or curve of a line, you need to activate and use the Fontwork tool.
- To add it to the Draw toolbar, choose Tools > Customize from the menu bar.
- On the Toolbars tab, in the Toolbars pull-down list select Drawing. In the Toolbar content section, click Add.
- On the Add Commands dialog, select Format from the left-hand list and the command Fontwork. Click Add, then Close to return to the Customize dialog.
- In the list of commands under Toolbar Content, move the Fontwork icon ] to the location you want by using the up/down arrows, and then click OK.
To write slanting text, follow these steps:
- Add the text to the connector as described earlier. The anchor location of the text is not important at this stage.
- Select the object with the text (in this case the connector) and click on the Fontwork icon to open the Fontwork dialog.
- To make the text lie along the inclined line, click the Rotate icon and set the distance to the line you wish.
The Fontwork dialog opens up many other possibilities to manipulate the text. You can, for example, turn the text around 180 degrees with the Orientation icon  (which was done in the example above) or place the text under the line by assigning a negative value to the spacing between text and line.
In addition, you can use the Fontwork dialog to generate curved text that follows the shape of a curved line. Experiment a little to investigate some of the possibilities.
