This example sets standoff attribute to cartesian axes to determine the distance between the tick labels and the axis title. Note that the axis title position is always constrained within the margins, so the actual standoff distance is always less than the set or default value. By setting standoff and turning automargin on, plotly.js will push the margins to fit the axis title at given standoff distance.
