"step" attribute for Slider widget

Community Support
1

Hello!
When I modify the “slider_app” example provided by adding a “step=0.5” attribute to the slider, I obtain the following error message:

ValueError: expected a value of type int8, int16, int32, int64, int or long, got 0.5 of type float

If I use “step=1”, everything works as expected. Any ideas why this is…?

Thanks for your help,

Max

PS: My bokeh/python versions are

···

python version : 2.7.9
bokeh version : 0.6.1

Max,

This is a bug, I have submitted a pull request that fixes it here:

  allow sliders to have float step size by bryevdv · Pull Request #1681 · bokeh/bokeh · GitHub

This fix will not make it into tomorrow's 0.7.1 release, but it will be in the next dev build we release on binstar.org (probably in about a week), as well as in the 0.8 release in mid-February. If you would like to try it even sooner, the instructions for installing from source are here:

  Contribute — Bokeh 3.3.2 Documentation

Thanks for the report,

Bryan
