I have a problem a bit complicated
First of all I have three diffirent dataset. I took them by 'data = new JDBCCategoryDataset()' function.
I want to create a bar chart and insert these three dataset into chart.
/********************************/
JFreeChart chart = null;
try {
Class object = ChartFactory.class;
Method method = object.getMethod(methodName,param);
chart = (JFreeChart) method.invoke(method,paramValues);
} catch (SecurityException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
/********************************/
I have created related chart.
After than I have inserted second and third category datasets by this for loop;
/********************************/
for (int i=1; i<catDataset.length;i++){
plot.setDataset(i,catDataset);
BarRenderer render = new BarRenderer ();
plot.setRenderer(i, render);
}
/********************************/
As a result I have taken this chart ; (bar behind each others)
