If you are extending WooCommerce by creating themes or developing plugins you will find this plugin to be priceless!
WooCommerce uses WordPress logic and database tables to store data on store items, orders, checkouts… 
If you are integrating a payment gateway or any 3rd party app with your store, you sometimes need to 
store some extra data for specific orders. It tends to be very hard or even impossible to extend orders 
with custom data.
<h4>Extend WC Orders</h4>
Here’s how easy it is to extend a WooCommerce order in your code:
| WC_CustomOrderData::extend($order);
To set a custom property to an order, just type:
| $order->custom->your_custom_property = ‘some value’;
After that you can use your custom order property by referring the “custom” order property:
| $custom_property = $order->custom->your_custom_property;
You can allways check if a custom order property exists using the standard PHP way:
| if(isset($order->custom->your_custom_property)) { doStuff(); }
All custom order properties are saved in a separate database table. When you finish working with the order, 
make sure you save custom data by typing:
| $order->custom->save();
Note: Storred objects and arrays will be restored as arrays.

Allows you to manage data sets via a spreadsheet interface and present that data in chart form via the Chart.js or <a href="https://github.com/methnen/m-chart-highcharts-library/" rel="nofollow ugc">Highcharts</a> chart libraries. The charts can then be embedded into a regular post via a handy shortcode.
Note: Starting with version 1.8 the Chart.js library is no longer on the 2.x.x branch which introduces some <a href="https://www.chartjs.org/docs/latest/getting-started/v3-migration.html" rel="nofollow ugc">breaking changes</a>. This will probably only affect you if you were modifying the default Chart.js behavior in some way.
Note: Starting with version 1.7 Highcharts is no longer included with this plugin by default. If you’d still like to use the features that require Higcharts please install the <a href="https://github.com/methnen/m-chart-highcharts-library/" rel="nofollow ugc">M Chart Highcharts Library</a> plugin before installing this update.
