In its current form, the process of zooming into charts to examine footprints is not intuitive. The charts zoom uniformly across both the X and Y axes up to a certain point, after which they continue zooming only on the X-axis, resulting in wider candles without the footprint values. This requires the user to stop scrolling with the mouse and either start dragging the time axis or hold Ctrl while zooming, a process that breaks the overall user experience. Exocharts handles zooming excellently.
