how many ticks will be for the graph in FuncTickFormatter?

hi,

Using FuncTickFormatter function, I constructed ticks. But I need to know how many ticks will be for the graph in FuncTickFormatter function as javascript variable

FuncTickFormatter ( code="""

…

…

//?? count of ticks

“”" % xlabel_dict)

how can I do that ?

regards

Hi Ahmet,

FuncTickFormatter doesn’t provide any way for your code to know anything about the collection of ticks, only about a single tick at a time.

In order to circumvent this, you have to write your own tick formatter that inherits FuncTickFormatter and overrides “doFormat” method. For more details look here https://bokeh.pydata.org/en/latest/docs/user_guide/extensions.html and here https://github.com/bokeh/bokeh/blob/0.12.13/bokehjs/src/coffee/models/formatters/func_tick_formatter.coffee#L16

It's also possible to inherit from the top level base, TickFormmatter

In Bokeh 0.12.15+, you will be able to use ticks variable (an array of all ticks), i.e. ticks.length. You can start experimenting with it now.
