vishalhkd Posted May 5, 2011 Report Share Posted May 5, 2011 Hi, We are using Chartfx 7.0 for java here at the census bureau. As long as we use the renderControl() method, the chart renders fine and we are able to access the charts via the AJAX toolbar. However, there are use cases where we need to generate the chart as an image and embed them in PDF reports. We are trying to use the exportChart() method for this and trying to create a PNG image as shown in the code example below .... However, the image produced by this method shows "Invalid ChartFX licenese" message. Below is the source sample for this. private File getChartFile(ChartData chartData, FileFormat fileFormat, Gallery gallery, AxisFormat axisFormat, int width, int height) { ChartServer chart1 = new ChartServer(); // Feeds in the chart data to chart server initChart(chart1, chartData); File tempFile = null; chart1.setGallery(gallery); try { tempFile = File.createTempFile("euschartfx", ".cfx"); FileOutputStream ostream = new FileOutputStream(tempFile); chart1.setFileContents(EnumSet.of(FileContents.ALL)); chart1.exportChart(fileFormat, ostream); ostream.close(); } catch (IOException e) { ExceptionController.getGenericException().handleAjaxWithRedirect(e); } return tempFile; } What are we missing here? Thanks,-- VishalIBM / Census Bureau Quote Link to comment Share on other sites More sharing options...
