New chart type: Number chart

Added a new chart type for dashboards: the number chart. The number chart displays a number on the dashboard instead of a line graph. Useful when a single value gives enough information at a glance.

The chart supports multiple ways of calculating the metric data for the timeframe selected, such as:

• Maximum value: Show the highest metric value.
• Minimum value: Show the lowest metric value.
• Average value: Show the average of the metric values.
• Total value: Show the combined value of the metric values.
• First value: Show the first metric value.
• Last value: Show the last metric value.

To add a number chart, go to your application in AppSignal, create or open a dashboard, click "Add chart", and select "Number" in the sidebar.
