How do I execute a object method

So I have a graph object. I would like to execute the show() method. How can I do that in the template


[var.graph.show()] doesn't work ($graph->show() normally in php)

thanks a lot

If your method is supposed to return a string, then [var.graph.show] should work.

ok thank you but mine method create a image witch the gd librairy. In fact I generate a image dynimically ...

Ok, si just calling $graph->Show() may be not enougth. I suppose you'd like to return the image path in the template.

I suggest you use a custom onformat function.
Example:

HTML:
PHP:

ok I will try that. Thank you for your help
