How do I format yaxis tick labels with comma as thousands seperator?

HoloViews

I would like to format my yaxis tick labels with comma as thousands seperator.

The below gets close

import holoviews as hv
hv.extension('bokeh')
data2 = {
    "x": [1,2],
    "Frequency": [100000, 200000],
}
hv.Histogram(data2).opts(yformatter='%.0f')

but does not add the commas.

If I change to yformatter='%,.0f' the plot just does not show.
`
It’s the same if I provide the function below to yformatter

def format_number(x):
    try:
        return '{:,.0f}'.format(x)
    except:
        return '%d%' % x

Any suggestions?

Problem solved using NumeralTickFormatter(format="0,0").

import holoviews as hv
hv.extension('bokeh')
from bokeh.models.formatters import NumeralTickFormatter
formatter = NumeralTickFormatter(format="0,0")
data2 = {
    "x": [1,2],
    "Frequency": [100000, 200000],
}
hv.Histogram(data2).opts(yformatter=formatter)

What if I want to add $?

df_with_salaries.hvplot.kde(y='average_salary', xformatter=formatter)

Add the $ in the format string:

formatter = NumeralTickFormatter(format="$0,0")
