Display the y-axis on the range of data value in the chart
Problem to solve
It would be ideal if we can only display the y-axis of data value ranges for charts. For example, the following Grafana chart visually shows you the changes of SLA over time while the metrics dashboard doesn't show you that much. You could inspect the gray zoom scroll area for overall patterns but that seems like an anti-pattern.
Not all charts should start from y = 0.
Using echart options:
boundaryGap: [0.1, 0.1], scale: true, allows us to manipulate the range of the axis.
