Editing Vertical/horizontal Axis labels of Flex Charts Using labelrenderer
There are many charting components are provided by Adobe with Flex Builder professional to develop rich Dashboard like applications.
There are many provisions are given with those components to format/change the way of displaying the data in charts.
There are also many direct properties are given with the charting components to made changes to the developers wish.
When looking with the Axis labels the developers can change the angle in which the labels to be display by using the property
labelrotation="angle"
If also the same developer want to change the font-size,font-face,apply style then that can be achieved by creating simple labelrenderer which extends label.
here is the example in this im displaying one coloumn chart and i want to display the horizontal axis in Red in color and in font-size 13 pixels.

In your post above, the line:
this.text = "";
should actually be:
this.text = value.text.toString()
