DatetimeRangePicker seems impossible to use

Hi,

This is not a question about how to code the DatetimeRangePicker, its more of a question on how to use it once it has been set up/is displayed on a server. I can easily change the end datetime of the picker however it seems impossible to modify the start datetime (it is possible to modify the start datetime’s date but seems next to impossible to modify the start datetime’s hour/minute). I have attached a video to display the issue I’m having. Any help would be appreciated.

Thanks,

Jack

Haven’t seen, perhaps it’s a bug but it’s not possible to speculate about anything at all without more information e.g. all relevant version and platform information and a complete Minimal Reproducible Example.

Hi sorry, I was really just looking for an example of someone using the datetimerangepicker on a server , but I am using Bokeh 3.3.0, and this is an MRE of my code used to generate the DatetimeRangePicker:

from bokeh.plotting import figure, curdoc
from bokeh.models import DatetimeRangePicker
from bokeh.layouts import row
def datetime_range_picker_cb(attr, old, new):
    print(new)
datetime_range_picker = DatetimeRangePicker(
    title="Select date and time range",
    value=("2019-09-20T12:37:51", "2019-10-15T17:59:18"),
    min_date="2019-08-01T09:00:00",
    max_date="2019-10-30T18:00:00",
    width=400,
)
datetime_range_picker.on_change("value", datetime_range_picker_cb)
layout = row(datetime_range_picker)
curdoc().add_root(layout)

Thanks,

Jack

@JackFrench2001 I can’t reproduce any issue with the code above with Bokeh 3.3.4 on OSX with Safari or with Chrome.

It’s not an issue with the code, I think I am just having trouble actually interacting with the widget once in the server, that’s why I was asking for an example of someone using it because I may just be using it wrong once in the server. Do you think you would be able to record yourself using it and post it? As I cannot seem to change the start datetime of the range but can do it fine with the end datetime.

Thanks,

Jack

@JackFrench2001 I clicked on a start date, and then (without clicking another date first) updated the time controls which updated the start datetime. Then I clicked an end date, and did the same to update the end datetime. I could click on another start date and repeat the process.

I do not understand what I am doing wrong then, because as attached in the video, when I click on a new date and modify the time, it increases the time of the end date. And if I click on a new date and click again, it will increase the time unit once but then go back to increasing the end time units even though I have not clicked anything else. Do you see anything wrong with what I am doing in this video?

This is what happens for me on OSX/Safari and latest 3.3.4 All I can suggest is:

• trying with the latest version (always adivsed, bugs are fixed all the time)
• try with another browser / platform (necessary data for a bug report)

Upgrading worked lol I’m stupid, sorry for wasting your time.

Jack

@JackFrench2001 no worries, glad it is working with latest!
