Cannot see "visible" lines!!!

[Birgi]

Hi,

In my chart I can see all the data points, but I cannot see the lines. "isLinesVisible()" method returns "true". However I have the following chart, maybe an image would help;



and my code for this chart is;

Code: Select all

		chart = ChartFactory.createBarChart(
											 criteria + " Grafiği",		// chart title
											 "Ürünler", 				// domain axis label
											 criteria, 					// range axis label
											 dataset, 					// data
											 PlotOrientation.VERTICAL, 
											 false, 					// include legend
											 true,						// tooltips?
											 false						// URLS?
											);
		chart.setBackgroundPaint(Color.lightGray);
		// creating the secondary chart & secondary axis

		CategoryPlot plot = chart.getCategoryPlot();
		NumberAxis axis2 = new NumberAxis("Satış Yüzdesi");
		plot.setRangeAxis(1, axis2);
		plot.setDataset(1, secondaryDataset);
		LineAndShapeRenderer lineRenderer = new LineAndShapeRenderer(true,true);
		plot.setRenderer(1, lineRenderer);
		plot.mapDatasetToRangeAxis(1, 1);
		plot.setDatasetRenderingOrder(DatasetRenderingOrder.FORWARD);

I desperately need help!!!
Thanks a lot

You need to look at how your dataset is constructed, because you don't have one series containing many data points, you have many series each containing one data point.

David,

Code: Select all

for(;;)
    System.out.println("Thank you very much!");

Thanks a lot

Sarika,

As David mentioned my problem was about my secondary dataset. I think I put every element in a different category. That was why they were not any lines between the data point. Now my graph is just as I wanted.

Thanks for your concern
