+## Advanced Usage - Custom Json Configs
+
+The `setJsonConfig()` method on every chart allows adding custom Apex properties not provided first hand by the package. 
+This means that any chart property supported by Apex chart can be passed down using this method.
+
+```php
+$chart->setJsonConfig([
+    'plotOptions.pie.startAngle' => -90,
+    'plotOptions.pie.endAngle' => 90,
+    'plotOptions.pie.offsetY' => 10,
+    'grid.padding.bottom' => -180,
+]);
+```
+
+>Note: If you want to add nested properties, you can use dot (.) notation for this matter.
+ 
+You can even pass down simple JS functions. For example, for formatting you can pass down your own closure
+
+```php
+$chart->setJsonConfig([
+    'tooltip.y.formatter' => '(val) => `$${val} million dollars baby!`'
+])

 Chart components must be placed inside a container with fixed height. This is because the chart will use all the given
