interactive glyphs

Community Support

I have a simple time series plot.

Now I need a layer over it that highlights specific ranges. Glyphs come to mind, something like the following:

fig.quad(top=[10], bottom=[0], left=[0], right=[100], color="#B3DE69", fill_alpha = 0.2)

``

Now the user should be able to add/remove such glyphs and adjust their left and right parameters. The bokeh server should then save these adjustments. BoxEditTool comes to mind, but the functionality I miss is editing left and right parameters. (I know that I can delete and add a glyph to change left/right parameters, but that is not an option, since zooming in and adjusting the left/right parameters is required).

Any way to interactively adjust the left and right parameters? Or completely different approaches to achieve highlighting of specific ranges?

I must be very lucky today. Thanks Bryan.

Will try it out tomorrow. The manual states that its main use case is to select a range which is to be magnified in an other plot. So I hope I can re-adapt it to my case where I need several ranges specified on a single plot.

There doesn’t seem to be a corresponding glyph on which the RangeTool could work. So although it looks nice, I don’t think I can use it for my case (adding/removing/adjusting ranges).

Hi,

I will be honest and say that I don't understand this statement. The range tool does not function on any glyphs, as the name suggests, the range tool is for updating range objects. However, you could add callbacks on the range objects, and those callbacks could update any glyph however you like. That would be a prototypical usage scenario in my mind. However, it's possible you have use-case requirements that were not considered, i.e. I didn't really have cases with multiple range tools in mind, or with adding/removing range tools either, so it's possible the current range tool is not suitable. It's hard to say without know more about what you are actually trying to accomplish.

Thanks,

Bryan
