Bar chart with ONE bar fills whole chart width. How to specify max bar width?

Hi,

I really appreciate that bar width sizes are auto calculated as the columndatasource changes.

However with only one bar the bar fills the width of the chart which looks ugly.

How can I specify a maximum bar width?

Regards,

Hi,

Bokeh does not alter bar widths or sizes, it uses exactly what you provide as-is. Rather, Bokeh normally automatically computes the plot ranges based on the data that is provided. By default, it adds 10% padding to either side, which, for a single bar will make the single bar take up most of the range by itself. But you can control this however you need:

  from bokeh.io import show
  from bokeh.plotting import figure

  p = figure()

  p.vbar(x=1, top=2, width=0.5)

  # set fixed padding, but could also be percentage
  p.x_range.range_padding = 2

  show(p)

Thanks,

Bryan

Hi Bryan,

I had similar issue on using hbar, tried it as what you suggested, it partially solved my problem, what I want is to fix the height of the bar in hbar chart, and also fix the distance between bars if there are multiple bars on it, does bokeh support it?

very appreciated your time & have a good day

Hi,

Please don't spam the same question multiple times on different (old) questions. As the maintainer of the project and list, doing that it makes it disorganized and personally stressful -- either the same answer now has to be duplicated in multiple places, or else we have to worry that users will run across the unanswered versions.

Thanks,

Bryan
