Plotly - how to format x-axis datetime to a custom format [12AM = 12a]?-CodePudding

I'm trying to change the format of my datetime x-axis ticks to be a specific custom format that matches the rest of my company's formatting.

using fig.update_xaxes(tickformat='%-I %p') I can get to a format that looks like this:

[12AM, 3AM, 6AM, 9AM, 12p, etc...]

But my desired output is this:

[12a, 3a, 6a, 9a, 12p, etc...]

Is there a way to do this simply using the tickformat options, or do I have do some sort of lambda function in addition? If so, what would that look like? Thanks so much for your help.

CodePudding user response：

Your format seams not to be available according to this list. You could format it yourself using ticktext and a formatting function which you probably already have, source here.

fig.update_layout(
    xaxis = dict(
        tickmode = 'array',
        tickvals = dates_array,
        ticktext = [compute_your_format_from_date(date) for date in dates_array],
    )
)
