 Save Chart Image when clickon on A HREF |

Hi,
is there a way for ChartDirector to return an image from the java web session when a user clicks on a link & then display a popup save image window?
The code below shows what I currently have. Currently, when user clicks on link it simply goes to another webpage with the chart image. But I want a popup window to appear so the user can save their chart.
Any guidance would be appreciated.
Thanks
HTML CODE
<a href="/MyJavaWebApp/ReturnImageOfChart" > Popup Save Window Here</a>
JAVA SERVLET CODE
WebChartViewer.streamChart(response, xyChart.makeChart2(Chart.PNG)); |

Hi Adrian,
According to the HTTP standard, the "Content-Disposition" attribute can be used. May be
you can try something like:
response.setHeader("Content-Disposition", "attachment");
WebChartViewer.streamChart(response, xyChart.makeChart2(Chart.PNG));

That worked. Thank you.
One last question. I read somewhere that version 6 of CD will be released in October. Is there a link detailing what changes will be included? Or at least tell us of some changes that will be in the release.
Thanks |

Hi Andrian,
The main features in ChartDirector Ver 6 are:
- Enhanced interaction support. For example, the programmable track cursors and drag to
zoom/scroll will support touch based user interface. There will be a "range control", which is
like a "scroll bar", but with the background of the scroll bar being a chart showing all the
data, and the handle of the scroll bar being a draggable and resizable window. The "range
control" can be used to select the range to be displayed on the main chart.
- Direct PDF output support
- Facelift for gauges and meters
- Many other graphics improvements, such as bar chart and box chart with rounded bars /
boxes, candlestick charts with hollow/filled style support, symbol offset support,
coutour/surface color specification in terms of data values, etc......
