Cewolf Legend coming twice

Hi,

The legend is coming two times.
Also color of the line is mixed with two colors w.r.t the legend shown

Code:
1) DatasetProducer

package com.test.graph;
import java.util.Date;
import java.util.List;
import java.util.Map;
import org.jfree.data.xy.XYDataset;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;
import com.test.graph.DAO.InvokeQuery;
import com.test.graph.bean.GraphBean;
import de.laures.cewolf.DatasetProduceException;
import de.laures.cewolf.DatasetProducer;
import de.laures.cewolf.tooltips.XYToolTipGenerator;
public class LineGraphDB implements DatasetProducer,XYToolTipGenerator{
public String getProducerId() {
return "XYDataProducer";
}
public boolean hasExpired(Map arg0, Date since) {
return System.currentTimeMillis() - since.getTime() > 0L;
}
public Object produceDataset(Map arg0) throws DatasetProduceException {
XYSeries series = new XYSeries("Bottom Text Here");
InvokeQuery iv = new InvokeQuery();
List<GraphBean> gbList = iv.getList();
for(GraphBean graphBean:gbList){
series.add(Double.parseDouble(graphBean.getX()),Double.parseDouble(graphBean.getY()));
}
XYSeriesCollection xyDataset = new XYSeriesCollection(series);
xyDataset.addSeries(series);
return xyDataset;
}
public String generateToolTip(XYDataset arg0, int arg1, int arg2) {
return "(x="+arg0.getXValue(arg1, arg2)+",y="+arg0.getYValue(arg1, arg2)+")";
}
}

Ceowolf XYZ chart

Hi,
I wanted to generate a graph such that the x axis is common and we have y-axis(on left) and z-axis (on right).
So that two graph with same horizontal point and different vertical point is generated.
Is this possible in vewolf
