You haven't provided any information about your environment, which makes it more difficult for people to help you. The "sticky" post in this forum ( https://www.zabbix.com/forum/zabbix-...lp-us-help-you) gives some examples of information you should provide about your environment.

If you want others to help you, make it easier for them to do so by thinking about what information they might need before they can answer your question.

Is this a new Zabbix install and the graphs have never worked correctly, or is this an existing installation that you've had for a while, and the graphs suddenly stopped working?

Since this is a problem with the Zabbix web interface (the "front end"), are you certain you have all the required PHP extensions installed?

Have you looked at the web server logs and/or the PHP logs, to see if useful error messages have been logged that might point you toward a solution?
