Driven Graphics Attributes
For any text, box, or line (or anything really) on a page, ReportMill lets you easily configure visual attributes, like color, text-color, font, stroke, size, location, etc. In fact, ReportMill lets you set more graphics design attributes than any other reporting package.
One of the most exciting advanced reporting features that ReportMill introduces is the unique ability to set most of these attributes dynamically based on conditions in the report dataset. This feature is accessed by selecting any individual shape in conjunction with the Shape General inspector.
In the example to the right, we have configured a given shape to have a red background if the value of getAmount is greater than 100.
Included in the list of attributes are the following color attributes:
The valid values of this attribute are any statically defined color name in Java.awt.Color presented as a string literal (case-insensitive), like "red", "green", "blue", "lightgray", etc. Additionally, colors may be provided in HTML hexadecimal style: "#FFA8C2". Hint: use the ReportMill color panel RGB sliders pane to get an exact HTML color string.
Also included is the "Font" attribute. Valid values for this include the simple case-insensitive string literal descriptors "bold" and "italic". You can also describe a font in terms of its name and size, like "Arial Bold 12" or "Courier Italic 14".
A powerful facility, used for things like DrillDown functionality, is the URL property. This can simply be a static string, like: http://abc.com. Or it can contain keys like:
Sometimes its handy to have an element that isn't even visible if a given condition is met. For instance, a text field with "Number of Children: @getChildrenCount@" might have the following property expression:
Another fun one is playing with the placement of a shape. In particular, you can build an impromptu bar chart in a table by setting its width dynamically to a ratio (times a default width). For instance, a group of movies might show their relative revenues with a key like this:
