Flux is InfluxData's new functional data scripting language designed for querying, analyzing, and acting on time series data. To learn more about Flux, see [Getting started with Flux](/{{< latest "influxdb" "v2" >}}/query-data/get-started).
1. Open the Data Explorer and click **Add a Query**.
2. To the right of the source dropdown above the graph placeholder, select **Flux** as the source type.
The **Schema**, **Functions**, and **Script** panes appear.
3. Use the **Schema** pane to explore your available data. Click the **+** sign next to a bucket name to expand its content.
4. Use the **Functions** pane to view details about the available Flux functions.
5. Use the **Script** pane to enter your Flux query.
1. Open the Data Explorer by clicking **Explore** in the left navigation bar.
2. Select **Flux** as the source type.
3. Click **Script Builder**.
4. The **Schema**, **Script**, and **Flux Functions** panes appear.
- Use the **Schema** pane to explore your available data. Click the **{{< icon "plus" >}}** sign next to a bucket name to expand its content.
- Use the **Script** pane to enter and view your Flux script.
- Use the **Flux Functions** pane to view details about the available Flux functions.
5. To get started building a new script, click **Script Builder**. Using the Flux script builder, you can select a bucket, measurements and tags, fields and an aggregate function. Click **{{< icon "plus" >}} Load More** to expand any truncated lists. You can also choose a variety of time ranges on your schema data.
6. When you are finished creating your script, click **Submit**.
7. Click **Script Editor** to view and edit your query.
8. If you make changes to the script using the **Script Builder**, you will receive a message when clicking **Submit** warning you
that submitting changes will override the script in the Flux editor, and that the script cannot be recovered.
* To get started with your query, click the **Script Wizard**. In the wizard, you can select a bucket, measurement, fields and an aggregate.

For example, if you make the above selections, the wizard inserts the following script:
```js
from(bucket: "telegraf/autogen")
|> range(start: dashboardTime)
|> filter(fn: (r) => r._measurement == "cpu" and (r._field == "usage_system"))
|> window(every: autoInterval)
|> toFloat()
|> percentile(percentile: 0.95)
|> group(except: ["_time", "_start", "_stop", "_value"])
```
* Alternatively, you can enter your entire script manually.
6. Click **Run Script** in the top bar of the **Script** pane. You can then preview your graph in the above pane.
