# Local Data Doughnut Chart

The Local Data Doughnut Chart field is an elegant way to visually display data that is on your bloc. It is a simple tool and does not do complex charts. For more advanced chart options, please see [Advanced Charts Set 1](/blocworx-documentation/bloc-editor/fields-tools-and-charts/charts-results-and-data-feeds/advanced-chart-set-1.md).

![A typical doughnut chart getting data from Field 1, 2, 3 and 4. Note that the fields do not need to be text fields, you can see Field 2 is a plain data field where the data may come from somewhere else.](/files/xr3H9AFusgzm0BOdaSQF)

{% hint style="danger" %}
To load the chart, at least one field in the bloc must have the [This field triggers Local Data Chart Updates](/blocworx-documentation/bloc-editor/managing-a-field/field-parameters/main-field-parameters.md#this-field-triggers-local-data-chart-updates) parameter applied to it. Then when the [rules/actions ](/blocworx-documentation/bloc-editor/managing-a-field/field-rules.md)start for that field, all local charts in the bloc rebuild/update. Please note, the chosen field to do this does not have to be in a chart, so it can be a seperate button or any other field.
{% endhint %}

{% hint style="success" %}
Hint: This field could be used in conjuction with our [Maths field](/blocworx-documentation/bloc-editor/fields-tools-and-charts/dynamic-output-and-variable-components/maths-field.md) or [Populate local field with Total from another Bloc](/blocworx-documentation/bloc-editor/managing-a-field/field-rules/populate-another-local-field-with-total-from-elsewhere.md) rule to get counts or numeric values from other places.
{% endhint %}

### Initial Field Parameters

There is only one parameter, which is the list fields to be included in the chart. Simply select the field and click "Add".
