Saving and mailing charts

[pca]

Hi everyone

 

 

 

In the FAQ section you mention that it is possible to mail the charts. How?

 

 

 

Due to the security problems mentioned there I'm trying to mail the chart after saving it as a file in the server by modifying the FusionChartsSave.jsp. The problem is that I want to have the options of saving the chart as an image, and mail it too. But if I change the FusionChartsSave.jsp file I can only do one of them. Which brings me to my question. Is is possible to send a parameter to the FusionChartsSave.jsp file or even to change the imageSaveURL according to the intended action?

 

 

 

Thanks in advance

Hi,

You can send URL encoded query string with in imageSaveURL.

 URL

 FusionChartsSave.jsp?CID=2&KB=1

 

 encoded URL

 FusionChartsSave.jsp%3FCID%3D2%26KB%3D1

i.e

 <chart ......  imageSaveURL='FusionChartsSave.jsp%3FCID%3D2%26KB%3D1'  ... >

Thanks for implementing this and stretching FusionCharts to this extent. Could you please share the code with the FusionCharts community so that you could help out a huge number of FusionCharts developers.

Thanks again

One of the parameters I had in mind was the destination mail. By passing them to the jsp file that way I would need to redraw the chart everytime I wanted to send a mail to a different destination, right?

 

 

 

Is there a way around that?

Hi,

 

 

 

Another option could be to save the charts on server, though this is experimental:

 

- In Java, create an instance of browser on server

 

- Load the chart in that (guess would have to build temporary HTML files with chart code)

 

- Use JavaScript API to automatically call the save script

 

- When saved, close the browser instance

 

- Use a queue manager to manage all the instances of browser.

So my choices are to reload the chart on the client side, or load it on the server side.

 

 

 

Is there no setImageSaveURL? It would be immensely helpful.

 

 

 

I can now send an email with the chart as an attachment, but I'm left with another problem. After I send the email, it moves to a blank page. If I redirect to the previous pages it loses the components that were on it. How can I stay on the same page? Like what happens when it sends back the image file to the client side.

 

 

 

Anyway, here is what I have so far. For now there are no settings defined by parameters. Hope it helps someone

Hi,

I am afraid, it is not possible as of now. setImageSaveURL is not available.
