Hi Siva,

Thanks for reply , Here my requirement is that I want to genrate Pdf for google chart. And when we set the randerAs="Pdf" then no script can be executed. As i find that google chart can be only created thorugh Javascript and Apex:page not support js when it sets as pdf.


Is there any way that I can genrate Chart from Apex class. So that after http callout i can insert the chart in attachement and then it can be easily shown in pdf.

If you have any solution/Idea plz reply.

Thanks

Hi Rohit,
Google chart is run by javascript but in render as pdf in visualforce page, javascript is not working.
you can use 'ImageChart' API for this. Create an image URL from the apex and then bind it in <img> tag in the VF page. Like This:
  
In Apex Class : 

String imageUrl = 'https://image-charts.com/chart?cht=bvg&chs=580x400&chdl=Offer|Demand&chdlp=b&chd=t:23|0&chco=16BFE7,ff8533&chxt=x,y&chxs=1N*cUSD0sz*&chxl=0:|12-Nov-2019'

In visualforce page : 

<img src="{!imageUrl }"/>
