Changing the y label for histogram in plotly express does not work

Hi I am using plotly express to plot a histogram.

import plotly.express as px

px.histogram(
    cdf,
    x='diag',
    histnorm='probability',
    labels={'diag': 'cosine similarity'},
    title='Cosine Similarity of Diagonal Samples',
    color_discrete_sequence=['green'],
)

The y label is shown as count, I want the y label to be called probability. I tried passing labels={'diag': 'cosine similarity', 'count': 'probability'} but that doesn’t work? How do I change the y label ?

Keeps happening in 4.14.3

I fixed it a little bit with yaxis_title but in the popup that appear when you put the mouse over the bars still shows “count”.

fig = px.histogram(
    n_orders, labels={"value": "# Pedidos", "count": "# Clientes"}
).update_layout(
    title={"text": "Numero de pedidos por cliente", "x": 0.5}, yaxis_title="# Clientes"
)
fig.show()

This works fine for me for both the y axis title and the hoverlabel… I’m not sure what the problem is.
