Hi fatma,
In your charting code, you may obtain the cookie parameters, and create the chart based on those parameters. For example, if one of your cookie parameters is the chart size, you may use that parameter as the chart size (instead of hard coding the size to a fix value).
Hope this can help.

Hi fatma,
Do you mean you want to store a chart in the cookie? In most browsers, the cookie is limited to a few KBytes. The chart is typically much larger in size. So it would not be possible to store the chart itself in the cookie.
The makeSession makes the chart image and stores it in a PHP session variable. In most PHH sysmtes, the PHP identifies the session by using session cookies, and automatically times out the session after a certain period of inactivity. You may refer to PHP documentation for more details on PHP sessions.
