Clearing Plot or Removing all glyphs

[Steven_Van_Buskirk]

@Bryan

It sounds like you are using a Bokeh server application? If so, then I was suggesting replacing a plot in an existing session:

some_layout.children[2] = new_plot

I haven’t tried that but it makes sense. Would that though solve this problem I mentioned before -

@Steven_Van_Buskirk

Now the bigger problem though is we have added custom tool extensions where by the user can mark up the plot with custom overlay annotations and we need those to persist across changes to the data.

I tried out removing the glyps via how you mentioned -

@Bryan

If you just have one simple plot with a legend then you can probably:

• remove the associated GlyphRenderer from .renderers
• delete the corresponding LegendItem from the Legend

Removing the legend item seemed to work fine but removing the glyph generated this weird effect where there looks to be a plot within the plot. Any ideas on this? -

The code looked something like -

fig = doc.get_model_by_name('main-figure')
line_glyph = doc.get_model_by_name('line-glyph-name')
fig.renderers.remove(line_glyph)

And yes this is all using bokeh server.
