* #505226 by Dave Reid and brmassa: Add PHP 5 dependency to charts.info

* Initial Port to Drupal 7

* [#470826] by brmassa and Panthrax

* [#261437] by brmassa

* [#473292] by Surrogard

* A warning on hook_requirements when the PHP version is below 5.2

* Functions moved from one file to other in order to improve performance

* [#447638] by acrollet and brmassa: Option to add label when using the 'Display sum of different values from one column' option

* Set the proper dependency on Open Flash Charts API module

* Small JS bug

* Google's Scatter plot now accepts individual point labels

* Node activity from Charts system fixed.

* Views integration now works after the internal data modification

* Color palette bugs fixed

* Better and more generic Google Charts code (and more improvements still to be made)

* Google pie charts now accepts multiple series

* Both Line and Pie charts using Google Charts uses the correct colors!

* Better merging between the default settings and the chart data.
* $settings['#series_attributes'] now stores all attributes that should be merged to series instead the main chart array.
* Color values are now transmitted with the # sign

* Settings attributes are again with the # sign. It makes the chart  display a lot easier.

* The new color system is now enabled. Well, the input part only. Now its time to actually use this color in the charts!
* Note take Charts module might use ColorPicker module to enhance the experience. But its now required.

* [#461660] by kenorb and brmassa: 'set default settings for charts' instead of 'access administration pages' access

* Views integration now uses the same settings form was the Default Settings page.
* It also consider the default settings

* All settings' attributes are not stored anymore with the #

* charts.admin.inc will deal with admin pages and form generation while charts.inc will deal only with common chart building routines
* _charts_settings() should be used instead variable_get('charts_settings') because it might initialize null variables
* _charts_settings_form() is now a separate function that might be used when a module wants to set custom settings for a given chart instead the defaults

* If there is no default chart provider or chart type select, now uses the first one enabled by default.

API Changes:
* The new hook_chart_types() set new chart types (like "Vertical Bar 3D")
* The '#types' on hook_charts_info() now only list the chart type code.

* Finally a Views integration worthy to mention! Based on the Karen Stevenson's code.
* Note that the Views integration now depends on Views Calc module
* Also note that Views Calc ALREADY has the same code, but its not fair to make her to maintain such unrelated code on Views Calc module.
