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.

Plotly.js 2.28.0 and later supports using base64-encoded typed arrays. To use a base64-encoded typed array, pass an object with the keys bdata
(a base64-encoded string or the ArrayBuffer of an integer or float typed array) and dtype
(the data type of the array, where the supported types are float64
, float32
, int32
, uint32
, int16
, uint16
, int8
, uint8
, and uint8c
). You can also specify shape
for multidimensional arrays. For example, '4,10'
would be a 2D array with 4 rows and 10 columns.
var x = 'VVVVVVVV1b8AAAAAAAAAAFVVVVVVVdU/'
var y = 'q6qqPquqqr4='
