Logarthmic scale

[plozachm]

Hi again,

 

I have another question... I am trying to use a logarithmic scale for a chart. I succeed in using it (have a look on valueExpression):

 

 

Code:

<categorySeries>
 <seriesExpression>
  <![CDATA[$F{mes} + "-" + $F{year}]]>
 </seriesExpression>
 <categoryExpression>
  <![CDATA[( $F{cdmcategory}.equals( new String("-unknown-"«») ) ? "Sin categoría" : $F{cdmcategory} )]]>
 </categoryExpression>
 <valueExpression>
  <![CDATA[( $F{tickets}.intValue()==0 ? new Double(0) : new Double (Math.log($F{tickets}.doubleValue())/Math.log(1.1)) )]]>
 </valueExpression>

 

But my problem is I would like to display real values on the X axis (with this solution it displays the logarithmic values).

 

I tried to use a customizer:

 

public void customize(org.jfree.chart.JFreeChart chart,

JRChart jasperChart){

CategoryDataset myPlot = ((Object) chart.getCategoryPlot()).getDateRange();

String temp = String.valueOf(myPlot.getColumnKeys().get(1));

chart.setTitle(temp);

}

 

I can change some stuff (Here I set the title to the value of the first category, not very useful but I was just testing...) of the chart but I have no access to the X axis labels.

 

Some ideas?

 

Thanks a lot in advance...
