# Class: CircularAxis
[axis](/solutions/geotoolkit/geotoolkit_js/apis/modules/geotoolkit.gauges#axis).[CircularAxis](/solutions/geotoolkit/geotoolkit_js/apis/modules/geotoolkit.gauges#circularaxis).CircularAxis
Implements an axis which uses Tick Generators to calculate number of ticks and their positions.
This axis calculates the ticks dynamically to not allow any intersections among labels and ticks.
The axis allows to render ticks and labels in three positions:
inside: tick growing from the inner bound of the axis towards the center
outside: tick growing from outer bound of axis towards the center

This option is similar to DOM Event bubbling, which allows
to get any event from child node. By default it is disabled
for better performance.
**`Example`**
```ts
import {Group} from '@int/geotoolkit/scene/Group';
import {Events as SceneEvents} from '@int/geotoolkit/scene/Node';
const parentGroup = new Group()
.setName('ParentGroup')
.enableEventPropagation(true);
const childGroup = new Group()
.setName('ChildGroup');
parentGroup.addChild(childGroup);
parentGroup.on(SceneEvents.Invalidate, (eventName, sender, args) => {
// Got notifications from all children of parent group
});
childGroup.invalidate();
```
#### Parameters

#### execute
▸ **execute**(`delegate`): [`CircularAxis`](/solutions/geotoolkit/geotoolkit_js/apis/classes/geotoolkit.gauges.axis-2.circularaxis.circularaxis)
Executes delegate and return the result. It allows us to keep all initialization calls in one place,
and we do not need to scroll up or down in IDE to find how and where it was initialized.
**`Example`**
```ts
// All setters (.setName() for example) returns reference to the this.
// In order to modify inner object like LineStyle or Pattern, to get this object (property) we should call getter to get object reference.
// Then modify it as shown below in Option 1 or you can use execute methods shown in Option 2.
import {Group} from '@int/geotoolkit/scene/Group';
import {Rect} from '@int/geotoolkit/util/Rect';
// Option 1
const group = new Group()
.setName('MyGroup')
.setBounds(new Rect(0, 0, 42, 16))
