## Elements
### Metric value
Elements are the basic building blocks of a canvas and they help you visualize data with different shapes and options. You can rotate and move elements around the canvas. When you move elements, snapping and alignment guides help you create more precise layouts.
The metric value element lets you easily select the data you want to display on a canvas. This element has a unique “edit” mode that can be triggered either through the context menu “Edit” option or by double clicking. When in edit mode you can select which field data that you want to display.
Add elements in the [Layer](#layer-options) section of canvas options.

## Connections
When building a canvas, you can connect elements together to create more complex visualizations. Connections are created by dragging from the connection anchor of one element to the connection anchor of another element. You can also create connections to the background of the canvas. Connection anchors are displayed when you hover over an element and inline editing is turned on. To remove a connection, simply click on the connection directly and then press the "Delete" or "Backspace" key.
When building a canvas, you can connect elements together to create more complex visualizations. You can also create connections to the background of the canvas.

1. Toggle on the **Inline editing** switch.
1. Hover the cursor over an element you want to connect to display the connection anchors:
1. Drag the cursor from a connection anchor on that element to one on another element.
To remove a connection, click the connection and then press the `Delete` or `Backspace` key.
You can set both the size and color of connections based on fixed or field values. To do so, enter into panel edit mode, select the connection, and modify the connection's properties in the panel editor.
You can adjust connections, adding angles to them, to fit the canvas you're working in. When you move connected elements, the connection resizes to fit the space.
{{<figuresrc="/media/docs/grafana/screenshot-grafana-10-0-canvas-service-graph.png"max-width="750px"caption="Canvas service graph">}}
- To adjust a connection, click it to display the midpoint controls and move those as needed.
- To make a connection a straight line again, move the midpoint back until the midpoint controls disappear.
If you move a connection so that it's almost a right angle or a straight line, the connection snaps into that angle or into a straight line.
### Connection styles
You can set the size, color, direction, and style of connections based on fixed or field values. To do so, enter into panel edit mode, select the connection, and modify the connection's properties in the panel editor. For more information on connection styles, refer to [Selected connection options](#selected-connection-options).

## Canvas editing
You can make changes to a canvas visualization while in the context of the dashboard, or in dashboard mode. The following sections describe the editing options available in dashboard mode.
### Inline editor
You can edit your canvas inline while in the context of dashboard mode.
You can edit your canvas inline while in dashboard mode. The inline editor menu displays the options relevant to the part of the canvas that you've selected. You can also move the editor window around.
The context menu lets you perform common tasks quickly and efficiently. Supported functionality includes opening and closing the inline editor, duplicating an element, deleting an element, and more.
The context menu is triggered by a right click action over the panel or over a given canvas element. When right clicking the panel, you are able to set a background image and easily add elements to the canvas.
The inline editing toggle lets you lock or unlock the canvas. When turned off the canvas becomes “locked”, freezing elements in place and preventing unintended modifications.
Toggle the switch to include experimental element types in the available selections.
#### Pan and zoom
You can enable panning and zooming in a canvas. This allows you to both create and navigate more complex designs.

### Layer options
### Context menu
The **Layer** options let you add elements to the canvas and control its appearance:
The context menu lets you perform common tasks quickly and efficiently. Supported functionality includes opening / closing the inline editor, duplicating an element, deleting an element, and more.
- [Elements](#elements-layer)
- [Background](#background-canvas)
- [Border](#border-canvas)
The context menu is triggered by a right click action over the panel / over a given canvas element. When right clicking the panel, you are able to set a background image and easily add elements to the canvas.
Use the **Add item** button to open the [element type](#element-types) drop-down list. Elements are listed in the reverse order that you add them to the canvas:
When right clicking an element, you are able to edit, delete, duplicate, and modify the element's layer positioning.
{{<figuresrc="/static/img/docs/canvas-panel/canvas-context-menu-9-2-0.png"max-width="750px"caption="Canvas element context menu">}}
By default, elements have numbered names, like "Element 1", and those numbers correspond to the order in which the elements were added, but you can [change the default names](#rename-an-element).
### Element snapping and alignment
You can also take the following actions on elements:
When you're moving elements around the canvas, snapping and alignment guides help you create more precise layouts.
- Change the order of elements by clicking and holding the row of the element while moving it up and down in the element list.
- Duplicate or remove elements by clicking the icons on the element row.
- Access the element editing options by clicking the element row. This displays the [Selected element](#selected-element-options) section of options. Click **Clear selection** to remove the element from focus and stop displaying that section of options.
{{% admonition type="note" %}}
Currently, element snapping and alignment only works when the canvas is not zoomed in.
