helo,
i'm doing a graph in jsp. i had succeeded to display the graph with data from the db. but some how, when i enlarge my graph size (width), the empty space on the right hand side of the picture(graph) also increases. i'd like to reduce the empty space. could someone show me which code should i alter? i tried some but it didnt work out. here's my line of codes..

------------------------------------------------------------------------

<%@ page import = "net.comrom.chart.*" %>
<%@ page import = "net.comrom.chart.gc.*" %>

String encode="jpeg";
//String uri=request.getRequestURI();
//String myurl="http://"+request.getHeader("Host")+uri.substring(0,uri.length()-12); //12 ist the length of my page name


response.setContentType("image/jpeg");
response.setDateHeader ("Expires",0);
// get output stream
java.io.OutputStream outb=response.getOutputStream();

// size of the chart image
int w=1200;
int h=600;

// data (looping)--------------
double[] d1= new double [noR.size()];

for (int i=0; i<noR.size(); i++){
%><%
String amik = (String)noR.elementAt(i);
double amik1 = Double.parseDouble(amik);
%><%
d1[i] = amik1; }

//----------------------------------------------------
LineDataSerie data1= new LineDataSerie(d1,new LineStyle(1f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_DOTS));
data1.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10);
data1.valueColor=GraphicsProvider.getColor(ChartColor.BLUE);
//data1.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10);

// create title
Title title=new Title("WIP for <"+pjkID+"> on <"+tarikh+">");
title.color=GraphicsProvider.getColor(ChartColor.MAGENTA);

// create axis
Axis XAxis=new Axis(Axis.HORIZONTAL,new Scale());
Axis YAxis=new Axis(Axis.VERTICAL,new Scale());
XAxis.tickAtBase=true; // draw also first tick
XAxis.ceroAxis=Axis.CEROAXIS_NO;
YAxis.ceroAxis=Axis.CEROAXIS_NO;
YAxis.scale.min=0;
YAxis.DescColor=GraphicsProvider.getColor(ChartColor.BLUE); //warna legend paksi y
YAxis.scaleTickInterval=20;//skala utk paksi y
XAxis.scaleTickInterval=1;
XAxis.bigTickInterval=1;
XAxis.DescColor=GraphicsProvider.getColor(ChartColor.BLUE); //warna legend paksi y

//String[] lbls={"1995","1996a","1997","1998","1999","2000","2001"};
// label paksi-x (from db-vector)
String[] lbls = new String [stationNameR.size()];

for (int j=0; j<stationNameR.size(); j++){

String test = (String)stationNameR.elementAt(j);
lbls[j] = test;
}

//String[] lbls = new String [pjkIDR.size()];
//pjkIDR.copyInto(String [] lbls);
//----------------------------------------

XAxis.tickLabels=lbls;
XAxis.style =new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_NORMAL);
YAxis.style =new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_NORMAL);
YAxis.gridStyle=new LineStyle(1,GraphicsProvider.getColor("0xC0C0C0"),LineStyle.LINE_NORMAL);
XAxis.gridStyle=new LineStyle(1,GraphicsProvider.getColor("0xC0C0C0"),LineStyle.LINE_NORMAL);
XAxis.axisFrame=true;
YAxis.axisFrame=true;

HAxisLabel XLabel= new HAxisLabel("Workcenter",GraphicsProvider.getColor(ChartColor.BLACK),GraphicsProvider.getFont("Arial",ChartFont.BOLD,12));
VAxisLabel YLabel= new VAxisLabel("No of panels",GraphicsProvider.getColor(ChartColor.BLACK),GraphicsProvider.getFont("Arial",ChartFont.BOLD,12));

// plotter
LinePlotter plot=new LinePlotter();

// create chart
Chart chart=new Chart(title,plot,XAxis,YAxis);
chart.XLabel=XLabel;
chart.YLabel=YLabel;
chart.addSerie(data1);
chart.back=new FillStyle(GraphicsProvider.getColor(ChartColor.LAVENDER));
chart.setSize(w,h);
chart.saveToFile(outb,"jpeg");
outb.close();
//-----------------------------------------------------------------------

Thank you.

Might it not be helpful to mention which charting package you are using?
