How to show text for zero value in bar chart?

[ckma0113]

if I set the data is like below:
let data =[ {
type: "bar",
x: ['A', 'b', 'c'],
y: [null, 0, 1],
text: ['NAN', '0', '1'],
textposition: "outside",
cliponaxis: false,
}]
when it render, it doesn't show text when the value of y is null or zero.

What plotly.js version do you have? I seem to recall this was fixed recently, though I can't find exactly where. null will never show the text, that means "there is no bar", which is distinct from "the bar has zero size". But in the current version of plotly.js the text shows on zeros https://codepen.io/alexcjohnson/pen/pogpbBx?editors=1010

I used the react-plotly.js, not plotly.js. Version is 2.4.0.
