An MX-only application is an application that does not
use any classes from the spark.swc file in its library path. The
main application’s root tag is the MX Application class, and no
components from the Spark component set are used.
You can use the Flex charting controls in MX-only applications.
However, some charting components such as the BarChart and ColumnChart
controls, use Spark components by default. As a result, to use charts
in MX-only applications, you must apply the MXCharts.css theme to
your application. This convenience theme file replaces the use of
the Spark Label classes with the MX Label class for the labelClass style
property.
To apply the MXCharts.css theme to your application on the command
line, use the theme compiler option, as the following example shows:
mxmlc -theme+=../frameworks/projects/charts/MXCharts.css
In Flash Builder, to apply the MXCharts.css theme, use the Additional
Compiler Arguments field on the Flex Compiler properties dialog
box.
If you set the compatibility-version compiler
option to 4.0.0, Flex applies the MXCharts.css theme by default.
