Description: Dashboard variables in visualization tools allow users to dynamically change the data displayed on metric dashboards. These variables act as filters that facilitate the customization of visualizations, enabling users to select different data dimensions without needing to modify the underlying query. For example, a user can create a variable representing different instances of a service, allowing them to visualize specific metrics for each instance on the same panel. Variables can be of different types, such as dropdowns, text fields, or ranges, and can be used in queries, titles, and labels. This flexibility not only enhances the user experience but also optimizes data analysis by allowing for deeper and more specific exploration of information. In summary, dashboard variables are a powerful tool in data visualization that enables users to interact more effectively with their data, tailoring visualizations to their specific needs and facilitating informed decision-making.
