[pmwiki-users] integrating google charts

[Ansgar Bockstiegel]

Wouldn't it be nice to edit the chart inside the wiki?
If we have a markup like (:gchart type=lc xsize=150 ysize=50 
data=justatest:) a recipe could transfer this to the corresponding img-Tag.
I just tested it. There are still things to add, but basically it works:

Markup('gchart',
       'directives',
       '/\\(:gchart(\\s+.*?)?:\\)/ei',
       'Keep(gchart("$1"))');

function gchart($unparsed_args){
    $args = ParseArgs($unparsed_args);
    $out = '<img src="http://chart.apis.google.com/chart?';
    $out .= 'chs='.$args['xsize'].'x'.$args['ysize'];
    $out .= '&amp;';
    $out .= 'chd=s:'.$args['data'];
    $out .= '&amp;';
    $out .= 'cht='.$args['type'];
    $out .= '" />';
    return $out;
}
