Hi,

I tried to export a Visifire Radar chart to Image using FJ.Core.dll in Silverlight 5. It is working fine if the chart is placed as a visible element in the UI.
Unfortunately I don't want to show the chart in the exporting window as the window size is very small. So I cant put the chart control as a visible UI element on that window. Is there a way to export the chart image with out showing it on the UI?. The version of Visifire chart is 4.1.5.0 and FJ.Core version is 1.0.0.0

Thanks in advance,

Jyothish

Jyothish,

It is possible in WPF only. In Silverlight, you have to render the chart first then only you will be able to export it.

Hello! how do I know when chart are rendered fully if now i have 3 or 4 Rendered events for any chart?! I use chart in Win Forms application with ElementHost control.

Melya,

Do you want this information at initial-render or at real-time?

Me interests initial rendering.

As i understand from this link if i have many Rendered events for one chart it means that some parameter was changed. Right?

You can use Rendered event of chart. It fires when the chart loads the first time and also fires when an element is updated outside PlotArea at real-time.

There is some way to invalidate and then update chart?

[vivek]

In Visifire chart updates whenever a property value changes or a DataSeries collection is changed. If you want an event at initial-render then Rendered event should work for you. Are you changing any property at real-time and trying to do some operation when chart updates?

Thnx for this! it is helpful!

But i have one more question!
If I try to capture image from chart, which in current moment in animation state, i got image on which animation not finished. how can i get image of finished chart? Also i cant disable animation before creating chart. I can disable it only after request of creating chart image.

Melya,

You should export the chart as image once the animation is finished, otherwise you have to disable the animation before exporting.
