minPadding property

double? minPadding
getter/setter pair

Padding of the min 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 lowest data value to appear on the edge of the plot area. When the axis' min option is set or a max extreme is set using axis.setExtremes(), the maxPadding will be ignored.

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