What parameters does it take?

Tag generates graph .png image, saves it to disk and returns path to the image. If tag is supplied with associated data array and file name it creates new graph to the file.

How do I use it?

To tray tag, put this to your page: 

'."{assign var='keys' value=','|explode:'Mon,Tue,Wed,Thu,Fri,Sat,Sun'}
{assign var='values' value=','|explode:'10,20,30,100,20,10,150'}
{assign var='data_array' value=$keys|@array_combine:$values}".'
<img src='{phpMyGraph file_name="uploads/test.png" data=$data_array}' />

Some usage scenarios

  • If you submit data array it will create and overwrite graph image.
  • If you don't submit data array or it is not an array it will return path to existing graph image.
  • If image path is missing it will use default img.
  • If image is missing on disk exeption will ocure;
