Customizing Chart Legend

Question

As per the API, a chart's legend has public-read protected access. However, when I extended the BarChart3D and tried to init the textFill and font, it failed to reflect in the chart. I also attempted overriding the legend which also did not result in the intended result. Does anyone have any insight that might help in this situation.
Here is my custom BarChart3D class (using init):
public class CustomBarChart3D extends BarChart3D{
     init{
          legend.textFill = Color.rgb(130, 175, 115);
          legend.font = Font.font("Times New Roman", FontWeight.BOLD, 12);
}Here is my custom BarChart3D class (as an override of the Legend):
public class CustomBarChart3D extends BarChart3D{
    override var legend:Legend = Legend{    textFill: Color.rgb(130, 175, 115)
                                            font: Font.font("Times New Roman", FontWeight.BOLD, 12)
                                            items: [LegendItem{text: "test"}, LegendItem{text:"test2"}]
}

This may be a case of CSS fighting with user initialized variables. Basically, the CSS pass happens after postinit so the values you initialize might be getting overwritten by CSS. The recommended way of dealing with this is to use CSS to style your legend. I didn't try this, but I think this will work.
     init{
          legend.style = "-fx-text-fill: rgb(130, 175, 115); -fx-font: bold 12pt 'Times New Roman';"
     }Or maybe in .css (I haven't tried this either)
BarChart3D *.Legend {
    -fx-text-fill: rgb(130, 175, 115);
    -fx-font: bold 12pt 'Times New Roman';
}FWIW, the "css overwrites user initialized variables" is a [known issue|http://javafx-jira.kenai.com/browse/RT-8851]. From the [css reference|http://download.oracle.com/docs/cd/E17802_01/javafx/javafx/1.3/docs/api/javafx.scene/doc-files/cssref.html] for JavaFX:

The application of CSS styles affects the values of JavaFX objects' variables. In many cases, JavaFX Script programs can write to these variables if they are public. This raises the possibility that CSS might overwrite values that had been initialized or assigned by a JavaFX Script program. Since CSS styles are applied asynchronously, it's possible that values might be assigned by a program and used for some time before being overwritten by CSS at an arbitrary time later. To avoid problems like this, the CSS implementation applies the following policy to some of the more common variables that are set by CSS style properties. The policy is: if at any point a JavaFX Script program ever writes to a variable of an object, that variable is henceforth never written by CSS, even if it had been set by CSS in the past. This allows JavaFX Script programmers to initialize variables in object literals, and to assign to objects' variables, without fear of those values being overwritten by CSS. However, it's probably best to avoid setting variables both programatically code and from CSS. With controls and charts, setting values from CSS is preferable.
This policy applies to the following JavaFX variables:
Label.textFill
Labeled.font
Labeled.graphicVPos
Labeled.vpos
Node.cursor
Node.effect
Node.opacity
PasswordBox.echoChar
Text.font
TextInputControl.font
