# navigator.yAxis.maxPadding

Padding of the max value relative to the length of the axis. A padding of 0.05 will make a 100px axis 5px longer. This is useful when you don't want the highest data value to appear on the edge of the plot area. When the axis' `max` option is set or a max extreme is set using `axis.setExtremes()`, the maxPadding will be ignored.

Also the `softThreshold` option takes precedence over `maxPadding`, so if the data is tangent to the threshold, `maxPadding` may not apply unless `softThreshold` is set to false.
