You can specify the toolbar location by passing the toolbar_location Positioning the toolbar ¶īy default, Bokeh plots come with a toolbar above the plot. This chapter contains information about all the individual tools and describes how Since they may respond to several gestures at once, anĮdit tool when activated will potentially deactivate multiple single-gesture tools. These are sophisticated multi-gesture tools that can add, delete, or modify Way, such as the HoverTool or CrosshairTool. These are passive tools that report information or annotate plots in some These are immediate or modal operations that are only activated when theirīutton in the toolbar is pressed, such as the ResetTool. The active tool is highlighted on the toolbar next to the These tools respond to single gestures, such as a pan movement.įor each type of gesture, only one tool can be active at any given time. Information, to change plot parameters such as zoom level or range extents, R = p.circle(x='x', y=0.5, source=source, size=30, alpha=0.Bokeh comes with a number of interactive tools that you can use to report #!/usr/bin/env python3įrom bokeh.models import ColumnDataSource, Span, HoverTool Here’s an illustrative example of adding hover tools that are effectively associated with the spans, and separate column data sources attached to populate with information of interest. I looked at the code snippet you provided, and it looks very well-written but in the interest of time, I chose to assemble a very small example of how to accomplish your goal so you can extend and integrate as it best fits into your larger application. The column data sources are not properties of the figure but rather the glyphs rendered in the figure. I’m not too sure how to tie the data for the annotations since it’s not part of the CDS I pass to figure (since the annotation data is separate). To view this discussion on the web visit \.

("(x,y)", "( " if the plot is using multiple data sources, it seems I am not able to use to specify a column.Īnd if i am not using a ColumnDataSource, how to make the mapping work? e.g. The doc shows I should do something like this to create a tooltip. By default hover tools try to hover for every glyph, but you can restrict different hover tools to different glyphs by using the. In this case you will need to make multiple hover tools. All columns in a given CDS must alway be the *same length* at all times (think of them like cheap Pandas DataFrames). If the glyphs have different data lengths then you will have to make separate CDS for them. That's another good reason to create your own CDS explicitly. If the data are all the same length, it's possible to drive multiple glyphs for a single CDS, in which case you can just make a single hover tool with whatever columns you want, from that one CDS. Bokeh will *always* use a CDS, but if you don't provide one yourself (like the example below) then Bokeh makes one, with some default column names depending on the glyph fields (e.g. If you are using cover tools, my recommendation is to always make your own ColumnDataSources, so that you know and control exactly what the column names are.
