Specifying text properties for titles, labels, axes, and legends

A graph can have four text elements:

Title
Labels for the axes
Text that shows the values along the axes
Legend

The sample shows a graph with the text elements labeled.

You can specify properties for each text element.

To specify text properties for the title, labels, axis values, and legend of a graph:

Select Properties from the graph’s pop-up menu and then select the Text page in the Properties view.
Select a text element from the list in the Text Object drop-down list.
Specify the font and its characteristics.

Using Auto Size

With Auto Size in effect, InfoMaker resizes the text appropriately whenever the graph is resized. With Auto Size disabled, you specify the font size of a text element explicitly.

To have InfoMaker automatically size a text element in a graph:

On the Text properties page for the graph, select a text element from the list in the Text Object drop-down list.
Select the Autosize check box (this is the default).

To specify a font size for a text element in a graph:

On the Text properties page for the graph, select a text element from the list in the Text Object drop-down list.
Clear the Autosize check box.
Select the Font size in the Size drop-down list.

Rotating text

For all the text elements, you can specify the number of degrees by which you want to rotate the text.

To specify rotation for a text element in a graph:

On the Text properties page for the graph, select a text element from the list in the Text Object drop-down list.
Specify the rotation you want in the Escapement box using tenths of a degree (450 means 45 degrees).

Changes you make here are shown in the model graph in the Design view and in the Preview view.

Using display formats

To use a display format for a text element in a graph:

On the Text properties page for the graph, select a text element from the list in the Text Object drop-down list.
Type a display format in the Format box or choose one from the pop-up menu. To display the pop-up menu, click the button to the right of the Format box.

Modifying display expressions

You can specify an expression for the text that is used for each graph element. The expression is evaluated at execution time.

To specify an expression for a text element in a graph:

On the Text properties page for the graph, select a text element from the list in the Text Object drop-down list.
Click the button next to the Display Expression box.

The Modify Expression dialog box displays.
Specify the expression.

You can paste functions, column names, and operators. Included with column names in the Columns box are statistics about the columns, such as counts and sums.
Click OK to return to the graph’s Properties view.

Example

By default, when you generate a pie graph, InfoMaker puts the title at the top and labels each slice of the pie with the percentage each slice represents of the whole. Percentages are accurate to two decimal places.

The following graph has been enhanced as follows:

The current date displays in the title
The percentages are rounded to integers
The raw data for each slice is shown in addition to the percentages

The sample shows a pie graph with more data than the default.

To accomplish this, the display expressions were modified for the title and pie graph labels:

Element	Original expression	Modified expression
Title	`title`	`title + " as of " + date(today())`
Pie graph labels	`if(seriescount > 1, series, string (percentofseries, "0.00%"))`	`if(seriescount > 1, series, string(percentofseries,"0%") + " (" + value + ")" )`
