[jCharts-users] Dependency on JDK 1.4

[Vikram R. <vr...@st...>]

There are portions of code which are dependent on JDK 1.4 but have not =
been documented in the javadocs. I found this when I was implementing =
the unfinished usePercentSigns in the AxisChart class.

The places in the code which I found to be 1.4 dependent are:

Legend.java (line 238) - Boolean.valueOf(boolean) is not implemented in =
JDK 1.3
------------ this.fillPointsFlags.add( Boolean.valueOf( =
pointChartProperties.getFillPointsFlag( i ) ) );

ChartDataException.java (line 53) - The Exception constructor used is =
specific to JDK 1.4
------------ super( message, throwable );

BarChartProperties.java (line 102) - Boolean.toString() is not =
implemented in jdk 1.3
------------ htmlGenerator.addTableRow( "Show Outlines", =
Boolean.toString( this.showOutlines ) );

I think these should be documented as such. If possible be changed to be =
JDK 1.3 compatible. All of these can be changed slightly make them so =
(except the ChartDataException constructor, I dont know how critical =
constructing an exception in that fashion is).

Yeah, we should remove these and keep the src runnable under 1.3

There is code in there which requires 1.4.x to compile though.  The image encoders use jdk 1.4.x
specific code.  But you can still run with 1.2 or 1.3 if you use the xxx13 encoder.

[Vikram R. <vr...@st...>]

yes, I am aware of the encoders dependency on 1.4 which is fine really.

Do you have a concrete plan to make the source 1.3 compatible. Some
timelines would be helpful. In the meanwhile, can I just go ahead and make
changes in the source and use it for my purpose? Are there any do's and
dont's there? I can mail the changes to the developers list if required.

Also, I think it would be a nice idea to create two separate build targets -
one for JDK 1.3 and one for JDK 1.4.

If resources are a problem, let me know how I can help out the project team
on this one. I like jCharts and I would like to contribute my two cents to
it.

thanks,
Vikram

[jCharts-users] Bug in User Guide

[Vikram R. <vr...@st...>]

In some examples in the user there is a reference to a class 'AxisCharts'
and its two members 'width' and 'height'. This class seems to be
non-existent. Is this from an older version of jCharts?

The user guide will need to be updated for the same.
