I want to add this:
I.e. the multiplier f (for femto in this case) to every tick, not only the powers of 10, as is the case already for linear scale. Is it possible to change this behavior?
I would prefer an answer that fixes this automatically by changing the behavior of Plotly, don't want to modify every tick manually.
You're trying to modify both the minor and major ticks. Right now nothing's built into Plotly's API to modify the minor tick formatting. However, I found a creative workaround.
You didn't share any programming code. I don't know if you're using a notebook or Plotly express, go, or Plotly as a backend. I don't know how your data is structured or how you called the axis to be log-scaled. That being said, without that information it's difficult to give you a solution that will regardless of what you're working with. (It's always better to share your programming code on a programming forum.)
This uses a Plotly example graph, go, and io. When I use the function io.write_html you may notice that I called several defaults to the defaults. I have to say that the Plotly documentation must not be up to date. The listed defaults are not necessarily defaulted.
This calls for a graph, and Javascript then combines the two into an HTML file that will automatically render in your default browser.
import plotly.graph_objects as go
import plotly.io as io
df = px.data.gapminder().query("year == 2002")
fig = px.scatter(df, x = "gdpPercap", y = "lifeExp", hover_name = "country", log_x = True)
js = '''
setTimeout(function() {
that = document.querySelectorAll('svg g.xtick')
that.forEach(el => el.firstChild.innerHTML = el.firstChild.innerHTML + ' f')
}, 200)
'''
io.write_html(fig = fig, file = "fig2.html", post_script = js,
full_html = True, include_plotlyjs = 'cdn', auto_open = True)
This reflects a 10k f which is something I doubt anyone would be looking for. However, it doesn't look like your data has that.
