Variables
Base64 Image/Video/Audio/PDF Panel supports dashboard and global variables in the Image URL panel option.
These three types of variables are explained in our Grafana Crash Course.
Example of dashboard variable in the Base64 panel
Below you can find an example of how a dashboard variable can be used to dynamically determine which file to display on the panel. The following blog post describes a project that integrates three open-source plugins to solve the task of uploading a file into a database and then immediately showing what has been uploaded.
The plugins used in the example are:
- The Data Manipulation to provide with the File type element for file upload.
- The Variable panel to provide a choice of what file to display.
- The Base64 panel to display a selected file.
If you are a visual style learner, you can watch the video. It covers the same ground.
