A lot of time when you plot a chart (say a bar chart here) for business you wants to emphasize the small variation between data, say daily you have roughly 5 millions messages sent but you need to visualize the 3k variations common each days. To utilize the landscape it's best for one to visualize not from zero but zooming in between 4.9m ~ 5.2m range instead of showing a slightly wiggling line.
While we could likely (I haven't get to it) to customize our chart to do that it'd be a good and handy option for the standard charts and Swift Chart would auto-adjust the range.
On top of it, being able to add standard axis break symbols would be a great help to keep it visualized and keep the chart honest.
