Smoothing Tool

Are you going to develop a smoothing tool for bokeh? I saw they have one in d3 java but before learning another plotting language I thought I should check if it is in development for bokeh.

Hi Jakub,

I'm not exactly sure what is meant by smoothing tool (or rather, I can imagine several possibilities). Can you provide more specifics or a link to the kind of tool you are thinking of?

Bryan,

Sorry I should have been more specific. I have data points and I can put a line between data points, however, if the data is noisy I would like to fit a spline, interpolate, etc. over a region of data then re-plot the data points (smoothed).

should we be doing that as a tool in the UI? or should we have functionality for doing that in the plot construction?

I see value in the tool UI for exploration… but it would be also more complex to do than a feature in the plot construction. BTW, I am not sure we have to provide “pre-processing” capabilities inside Bokeh itself. So, I would be inclined to a UI tool…

Hugo I see the workflow: selection -> drives smoothing over just the selected points.

A IU tool is what I was referring to like the select or zoombox tool. I do not want to only smooth over a few points. I would like to smooth the whole data set using the 3 to 5 nearest neighbors to re-calibrate each point. This is a common practice in astronomy when we are looking a spectrum from a star. And being able to do this over the web would really be useful in combination with the other advantages bokeh has in plotting.

Jakub,

Can you describe the actual interaction more? I had suggested possibly having a selection inform the smoothing but you seem to say this is not what you are suggesting? If the whole data set is to be smoothed, what part it input from the user? Do you mean parameters for the smoothing should be specifiable from the page the plot is on? If so I think we just have a terminology mismatch. Bokeh has the ability to have widgets like sliders and drop downs that inform computations. Is that what you mean? By "tools" we usually mean specifically tools that act on the canvas: zoom, pan, select, e.g., but it does not seem that that is what you are asking for?

Bryan
