Jfreechart, symbolAxis and state encode

[etantonio]

Good Evening for a chart concerning four three state I want to use
JFreeChart and symbolAxis,
my problem is that I've the following code values :

1 RX comando

2 PLL agganciato

3 PLL sganciato


while using symbolAxis it automatically give the following encode :

0 RX comando

1 PLL agganciato

2 PLL sganciato


my question is how to have an arbitrary code associated with the
labels ?
There's a way ??

Thanks,

The SymbolAxis constructor takes an array of String values, which can
include any characters you want:

<http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/axis/SymbolA
xis.html>

I don't see how SymbolAxis would alter your choices. Perhaps an
<http://pscode.org/sscce.html> would help.

the array of String values for me contains "RX comando" , "PLL
agganciato", "PLL sganciato"
from my engine arrive to this chart just the values 1,2,3 so I
couldn't pass it directly to the chart,
that would be nice if I could give to SymbolAxis a similar array that
tells the value associated with the corresponding label.

I guess you could set the symbol for value zero to the empty string and
negate setAutoRangeIncludesZero. Tinkering with setAxisOffset might be
helpful, too. Also, try searching the demos for "SymbolAxis".

Of course, without seeing your <http://pscode.org/sscce.html>,
I'm guessing.
