external visualisation (php script with sysinfos)

Hi guys,

I fight hard with the visualization... :-(
I'm just doing me in the dashboard to create new visualizations ...
I want view the core temperature, uptime etc from my Pi....
As far no problem ... The php script runs exactly fine and stable...

In my Dashboard only displays an empty white container.?
 

For the menuentry is have modified the vis_render.js

"sysinfo":
    {
      "offsetx":0,"offsety":0,"width":400,"height":300,
      "menu":"Visualisations",
      "html":""
    },
 

Thats ok...

 

But how can i tell my new visualization that it needs to call a PHP script ...???

Can someone give me a hint?

Thank you very much

Matthias
