Minimum Vbar Width for hovering over it

Community Support

I am creating a Vertical Bar based on my time records during the 2018.

I was creating a Vertical Bar

hover_2=HoverTool(tooltips=[(‘main activity’,’@main_activity’),(‘Count’,’@Count’),(‘Date’,’@Date{%F}’)], formatters={

‘Date’ : ‘datetime’})

plot=figure(title=‘Daily Hours’,tools=[hover_2,‘pan’,‘wheel_zoom’],plot_width=400, plot_height=400,x_range=(xrange), y_range=(yrange))

plot.vbar(x=“Date”, top=“Count”,source=source, width=1000000)

``

What I have discovered that in a time span of 365 days (1Y)

I can hover and get the required information only if the width is at least “1000000”

With Smaller Values I am not able to hover over the graph.

The first example is with a width value of 1.5.

The second example is with a width value of 1000000

  1. Why this kind of behavior?
  2. How to know the minimal width?

Hi,

Please see this SO answer:

  python - Bokeh: The widths of vertical bars doesn't change - Stack Overflow

Thanks,
