public class IlvQuarterTimeScaleRow extends IlvBasicTimeScaleRow
IlvBasicTimeScaleRow
to provide a complete scale displaying
quarter intervals.
By default, each quarter interval is displayed with a text partly formatted
using a java.text.SimpleDateFormat
created with the "yyyy"
string.
The exact result depends on the year mode and on the string chosen to
display the "Quarter" text.
For example, by default, if year mode is set, the result will be
"Qtr. 1 1998" for January 1998.
The Quarter timescale row supports alternate locales by utilizing resource files. The resource files are documented here.
