Title: Bugfix/redraw nav stick min

Encountered this defect while implementing an auto-updating chart with the Series `setData` method. I think the intent was to ensure that the new range (newMin -> newMax) cannot fall off the left edge of the chart, but that should be measured from baseMax and not baseMin.
