hi, Very good tutorials. I'd like to see how I can add the axes of the coordinate system because now I do line charts and it was nice to add them, may be an option for drawing the coordinate axes ? thanks

Nice thank you! I was struggling to get my data from Database and get it onto the Chart but your video gave me an idea. For anyone having the same issues: DatabaseConnection connectionToDatabase = new DatabaseConnection(); Connection connection = connectionToDatabase.getConnetion(); // get database connection ArrayList years= null; // list for years (Stored in database as VarChar) ArrayList price = null; // list for price (stored as Int in database) try { // get data for years stored in list years = connectionToDatabase.GetYearsFromSharePrice(jTextFieldCompanyIDFieldChart.getText()); } catch (SQLException ex) { Logger.getLogger(ChartJFrame.class.getName()).log(Level.SEVERE, null, ex); } try { // get data for price stoed in List price = connectionToDatabase.GetPriceFromSharePrice(jTextFieldCompanyIDFieldChart.getText()); } catch (SQLException ex) { Logger.getLogger(ChartJFrame.class.getName()).log(Level.SEVERE, null, ex); } Collections.sort(years); // sort the X axis DefaultCategoryDataset dataset = new DefaultCategoryDataset(); for(int j = 0;j < years.size(); j++){ for(int i = 0; i < price.size(); i++) { dataset.setValue(new Integer(price.get(j)), String.valueOf(price.get(i)), years.get(j)); break; } } Full project: github.com/venetsia/DesktopShareTraderApp
