When building a graph and adding a range slider to it, when the code is run, the entire graph is built and after using the slider, you can change its size. Is it possible to make the graph immediately display from the values of the step to the range slider?
Typically for the “initialization” type of thing I just instantiate the bokeh object (model, figure, CDS, whatever the thing the callback is gonna modify), with the same parameters as the initial value of the callback object. I haven’t found a way to run a callback “on page load” yet/I seem to recall reading that you can’t. Is this what you’re asking about?
