I have implemented the google charts example with the help of my own database . The issue that i am facing is that even if i have set the app variable when the page is mounted still i am not able to get the chart displayed as the page is mounted. If i add a button and on the click of the button try to set the value for the page variable then the chart gets displayed.
The issue that i am mentioning is in the mobile device itself . In the mobile device even if i set the page variable on the click of page of mounted it does not display the chart but when the same page variable i set on the click of a button then the chart is displayed .
