HOw to run ant javadoc

[Manfizy]

I just downloaded jfreechart class library and am supposed to run ant javadoc to generate javadoc.
How hv no idea on how to go about it
Any1 with an idea??

[Eranga]

Can you explain bit more clearly what you want to do? Looking to generate Javadoc for a library?

Exactly, i want to generate javadoc for jfreechart class library.How do i go about it??

[MK12]

Most IDE's do it by just clicking an option, but I don't know how to do it manually. Maybe try downloading NetBeans if you can't figure out how to do it manually.

am actually using netbeans IDE,but for it to work on netbeans u must generate it and add it as you add the class library.I dont know whether you understand what am trying to say?

-----------------
how about the avatar?it looks cool.mk for me one!

[MK12]

Oh ok I wasn't thinking of the same thing then sorry.
I'll make you a java avatar today though, I'll post it in this thread.

hello manfizy,

i am also using jfreechart with netbeans.
what you exactly want? you want add the javadoc to the IDE? or what?

Yep,thats what i want to do.
Btw,how do you find jfreechart?are you good in it?
Am trying to create a line graph using vaues read from a file and am in total darkness.
May be we can share ideas on this if u dont mind.
Can you please give me a simple code of plotting a line graph?

i downloaded it from sourceforge.com
its not that much hard.. i usually use it to plot a 3D bar chart for my application.
ya sure, we can share.. actually i too have not used it completely...

see below there is a sample code for a line graph chart

// i am having data in double.. you can read your file and manipulate them in double array
final double[][] data = new double[][] {
            {5.0, 12.0, 4.0, 6.0, 16.0, 5.0, 7.0, 15.0},
            {6.0, 5.5, 7.0, 5.0, 3.0, 4.0, 0.0, 3.0},
            {3.0, 4.0, 3.0, 3.0, 7.0, 4.0, 3.0, 2.0},
           {1.0, 2.0, 3.0, 4.0}
        };


        Comparable[] series = {"Series A", "Series B", "Series C", "Series D"};
        Comparable[] type = {"N 1","N 2","N 3","N 4","N 5","N 6","N 7","N 8"};

        final CategoryDataset dataset = DatasetUtilities.createCategoryDataset(series, type, data);
JFreeChart chart = null;
// here we plot the graph
chart  = ChartFactory.createLineChart("Bar Chart", "", "", dataset, PlotOrientation.VERTICAL, true, true, true);

thanks

thanx for your sample code.its actually working properly but there is something that is not clear to me.why do you have type on the x axis as in can i compare two variables lets say time and power level in a power plant where we have time on the x axis and power level on the y axis

[MK12]

I'll try to make the Java pic tonight, might be finished in a few hours. check back then. (By the way to make them I'm just using pictures from google and then editing with GIMP)

hello,

i could not understand what you exactly want to say..
please make it clear...

and if you are working on jfreechart then please tell me... i have an issue with it. then we can discuss about this.

thanks

Ok,to me the example code that u gave me looks like you were trying to plot a bar chart coz you have comparable type N1 - N8 on the x axis and the variables on the y axis. Now,my question is very simple,what if i want to plot a line graph of two variables,lets say time against powerlevel. How can i modify your code to do that? I hope now am clear enough.

Initially i was working on Scientific graphing tool(SGT), pretty powerful tool but it was alil bit difficult for me coz i couldnt achieve what i wanted. So now have just turned back to jfreechart which i hope we are going to share ideas and achieve something.

thanks for your kind response

ya you r abs rt...
the two varibales there are for barchart...
try your code and if find any bug then please discuss...

if you goto the bar chart then pls do tell me
i hv something to discuss..

thanks

hey, the bar chart is working properly.no bug..
Am trying to modify it to xy plot.
Any idea on which method to apply here?

you can bring up the discussion now.think am good to go..

cheerz!!

what was your discussion about??

[neeraj.singh]

for xy chart you have to use xyseries
like this
final XYSeries series = new XYSeries("Random Data");
series.add(99, 400.2);
series.add(5.0, 294.1);
then
final XYSeriesCollection dataset = new XYSeriesCollection(series);
here you get the dataset for the graph now do the same with JChartFactory to plot the graph

This is how i implemented it but i still get an error.
check it out

package myjfreechart;

import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.CategoryDataset;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;

/**

public class Main {

    /**
     * @param args the command line arguments
     */
public static void main(String[] args) {

final XYSeries series = new XYSeries("Random Data");
series.add(99, 400.2);
series.add(5.0, 294.1);
        
final XYSeriesCollection dataset = new XYSeriesCollection(series);

JFreeChart chart = null;

chart  = ChartFactory.createLineChart("Line Graph", "Time(Hrs)", "Power Level(%)",(CategoryDataset) dataset, PlotOrientation.VERTICAL, true, true, false);

// create and display a frame...
ChartFrame frame = new ChartFrame("First", chart);
frame.pack();
frame.setVisible(true);
    }

}

where am i makin errors?

thanx

hey dear
you are created dataset with XYSeries and
ploting the LineChart graph .....
plot the xy... chart

thanks

Scheiße!!why was i not seeing this??
Its now working after using the xy plot.

I can now see light at the end of the turnel.hehehehe!!

Thanx so much :-)
