Hook chart_post_build to append custom GIC parms

Subscribing. I like this idea but from memory (only) I think that each parameter needs more than just being thrown into an arguments array, so I don't think it'll be as simple as we might hope.

+1 for Google Chart API to add some methods for adding arbitrary / custom params and / or hooks for implementing external aspects.

+1.

The module should have another _alter hook that would allow to modify the $data array build with the url attributes.

Example patch.

A simple inplementation of the #scale param would be.

<?php
/**
 * Implementation of hook_chart_after_build().
 */
function chart_extra_chart_after_build($chart_id, $chart, &$data) {
  if ($chart['#scale']) {
    $data['chds'] = implode(',', $chart['#scale']);
  }
}

I don't know if this is the right place for this, but I'm having trouble getting the correct data labels on my bar chart. After I applied '#adjust_resolution', my data does display properly, but with the following code, it only displays the scaled values on the labels (i.e. between 0 and 100) and not the actual values.

$chart['#shape_markers'][] = array('N','f3f3e4', 0, 0, 20, '', 're');
#also tried this, but basically just returned the same value with a dollar sign in front
$chart['#shape_markers'][] = array('N*cUSD0*','f3f3e4', 0, 0, 20, '', 're');

I applied the chds patch and tried a few things out, but no cigar. Any ideas on how the get the correct values on my labels?

Committed to 6.x-1.x and 7.x-1.x with minor modification.

    // Creates hook_chart_post_build($chart_id, &$chart, &$data)
    foreach (module_implements('chart_post_build') as $module) {
      $function = $module . '_chart_post_build';
      $function($chart['#chart_id'], $chart, $data);
    }

Please document this in chart.api.php
