    Charts and PDF

      I am a complete newbie to Flex (have used some flash before). I am evaluating Flex 3 for charting. I wanted to know how does one create a PDF (on the server) that is an exact representation of a chart that the flex charting creates in the browser client? Are there APIs one can use on the server to create such a PDF?
      Does one have to buy "LiveCycle PDF generator" just for this feature?
      Thanks in advance.

          If you want an exact reproduction of the displayed chart you can capture the display and send it to the server as a png or jpeg file. API for creating the PDF file depends of the server you use. Flex is only for the client side.
          exemple :
          var bmp : BitmapData = new BitmapData ( chart.width, chart.height ) ;
          bmp.draw ( chart ) ;
          var png : ByteArray = PNGEncoder.encode( bmp ) ;
          // here send png to your server....

          Have a look to alivePDF which can create a PDF file from Flex on the client side.

            However, what if there is no displayed chart for a particular data set on the client.
            For example: Google Analytics displays the charts (they are using flex I am guessing). Plus, they also have a way to schedule sending these reports in email.
            Now, when these reports are generated (at some later time) its all pure server side code. I am looking to solve this scenario.

              Well Flex charts are components made to be interactive. I doubt that a server side solution implements the exact same visual aspect chart, but may be...
              If you choose Flex to generate server side reports including charts, I think you are on the wrong road.

                hmm .. no I think you misunderstand me.

                1) I do want client (browser based) interactive flex charting.
                2) However, I also want to be able to generate offline - server side reports in PDF that can be emailed - which should look - <b>as if </b> - a snapshot of the chart on the client was taken.

                Google Analytics is doing it. They have live charts plus offline scheduled emailed reports containing snapshots of these charts. I dont know if they have some sort of a client emulation on the server side or something. I dont think they are creating separate images on the server - they are somehow taking a snapshot of the flex app on the server side in an image and to a PDF and then emailing that.
