To delete a single data point in Grafana, you can follow these steps:
- Open the Grafana web interface and navigate to the desired dashboard.
- Click on the panel where the data point you want to delete is located. This will open the panel in edit mode.
- Locate the specific data point you want to remove within the selected panel.
- Hover over the data point until a small circle or an options icon (three vertical dots) appears near it.
- Click on the circle or options icon to access additional actions.
- Choose the "Delete" or "Remove" option from the available actions.
- Confirm the deletion when prompted.
By following these steps, you can successfully delete a single data point in Grafana without the need for using list items.

How to delete a specific data point from a specific data source in Grafana?
To delete a specific data point from a specific data source in Grafana, you will need to locate and access the database associated with the data source.
Here is a general outline of the steps involved:
- Identify the data source: Determine which data source is being used in Grafana. It could be Prometheus, Graphite, InfluxDB, or another supported database.
- Access the data source: Depending on the data source, you may need to log in to the database system, access the command-line interface, or use a web-based UI.
- Locate the data point: Find the specific data point you want to delete. This may involve querying the database or browsing the available data.
- Delete the data point: Once you have located the relevant data point, use the appropriate command or action to delete it. The method will depend on the database being used.
- Verify the deletion: Confirm that the data point has been successfully deleted by checking the database or refreshing the Grafana dashboard.
It's important to note that Grafana is primarily a visualization tool, and data management is generally handled in the underlying data source. So, the specific steps and commands for deleting a data point will depend on the database you are using. Consult the documentation or resources specific to your data source for further guidance.
How to delete a data point from a continuous query in Grafana?
In Grafana, continuous queries are used to summarize and aggregate data from a data source, such as a time series database. If you want to delete a specific data point from a continuous query, you will need to modify or delete the underlying raw data in the data source itself.
Here are the general steps to delete a data point from a continuous query in Grafana:
- Identify the data source used in the continuous query. It could be a time series database like InfluxDB or Prometheus.
- Access the data source directly and query for the specific data point you want to delete. The method to query and modify data varies depending on the data source. For example, if you're using InfluxDB, you can use InfluxQL or Flux to query and modify the data.
- Once you have identified the data point you want to delete, use the appropriate method provided by the data source to remove it. This could involve updating the value of the data point, deleting the specific measurement or deleting the entire series that contains the data point.
- After deleting the data point, the continuous query will be triggered to re-aggregate the updated data. This may take some time, depending on the size of the data set and the configuration of the continuous query.
- Refresh the Grafana dashboard or panel that uses the continuous query to see the updated data.
Note: Deleting a data point may have implications for the aggregated summary data or graphs in any other panels or dashboards that rely on the continuous query. Make sure to consider the consequences and plan accordingly.
How to create a data point in Grafana?
To create a data point in Grafana, you would typically follow these steps:
- Start by logging in to your Grafana instance and navigating to your desired dashboard.
- Click on the "Add panel" button (which usually looks like a plus "+" sign) to add a new panel to the dashboard.
- After adding the panel, click on the "Edit" button (usually represented by a pencil icon) to bring up the panel configuration settings.
- In the panel editor, navigate to the "Metrics" tab (or any tab related to data sources or inputs, depending on your data source type).
- Under the relevant data source section, specify the necessary metric details such as the measurement or metric name, along with appropriate filters or tags if applicable. This may vary depending on the data source you are using (e.g., Prometheus, Graphite, InfluxDB).
- Configure any additional settings related to your data point, such as the time range, visualization type (e.g., graph, table), and other customization options specific to Grafana.
- Once all the necessary details and settings are correctly defined, click on the "Apply" or "Save" button to save the changes and add the data point to your Grafana panel.
- Finally, check your panel on the dashboard to see the visual representation of the data point you created. You can further customize and arrange the dashboard as desired.
Note: The specific steps and configurations may slightly vary based on the data source and the version of Grafana you are using. Always refer to the official Grafana documentation or relevant resources for accurate and up-to-date instructions.
How to connect Grafana with a Prometheus data source?
To connect Grafana with a Prometheus data source, you need to follow these steps:
- Install and configure Prometheus: Firstly, you need to install and configure Prometheus on your system. You can download Prometheus from the official website and follow the installation instructions provided in the documentation.
- Install and configure Grafana: Download and install Grafana on your system following the official documentation. Once Grafana is installed, you can access it via your web browser.
- Add Prometheus as a data source in Grafana: In the Grafana web interface, go to the Configuration section and select "Data Sources." Click the "Add data source" button and choose Prometheus as the data source type.
- Configure Prometheus data source in Grafana: In the data source configuration page, provide the required details such as the URL of your Prometheus server and a name for the data source. You can also modify other settings as per your requirements.
- Test and save the configuration: After providing the configuration details, click the "Save and Test" button. Grafana will test the connection to the Prometheus server and show a success message if the connection is successful.
- Use Prometheus data in Grafana dashboards: Once the connection is established, you can create dashboards in Grafana and use Prometheus as the data source. You can create visualizations, customize queries, and explore your Prometheus data using Grafana's rich set of features.
By following these steps, you can connect Grafana with a Prometheus data source and leverage Grafana's visualization and monitoring capabilities for your Prometheus metrics.
