To set decimal points on axis

in the uploaded figure, is it possible to set auto adjusted axis points with two decimal points
example 82 to 82.0,81 to 81.0

Here’s how: http://codepen.io/etpinard/pen/qNoOzX

I interpreted it wrong. To see the actual value I must hover over the point.

Disregard- I don’t think it’s working. The significant decimal value is always 0. Tried to follow the format documentation and it doesn’t work.

Plotly.plot(‘graph’, [{
y: [80.013, 80.154, 80.863]
}], {
yaxis: {
tickformat : “.3f”
}
})

Thanks
