Tabbed plots require a unique source?

Community Support
1

I’m trying to collate similar, but different, plots, based on the same data source, into a single page with the tabbed pane layout.

Initially, I’m just trying to plot two scatter ones. They use different axes, but the source dataframe is meant to be the same. However, unless I created two unique source instances, it would only plot the second plot - in both tabs.

source = ColumnDataSource(data)

source2 = ColumnDataSource(data)

p1 = figure(tools=TOOLS, title=y[:-9])

p1.scatter(x=OC, y=HC,source=source,radius=radii, color =‘mz’,fill_color=colors, fill_alpha=0.75,line_color=None)

tab1 = Panel(child=p1, title=“Plot1”)

p2 = figure(tools=TOOLS, title=y[:-9])

p2.scatter(x=Cno, y=DBE,source=source2,radius=radii, color =‘Ono’,fill_color=colors, fill_alpha=0.75,line_color=None)

tab2 = Panel(child=p2, title=“Plot2”)

tabs = Tabs(tabs=[ tab1, tab2 ])

output_file(path+“two-plot.html”, title=“test”)

show(tabs) # open a browser

``

When I have source=source for both (and no source2), both tabs show the second plot.

Is this a feature or a bug?
Is it because they are both scatter plots?

Are OC, DBE, etc the string names of columns in the data source? Or actual arrays/lists? If the latter then the default-created columns are probably overwriting each other! We are probably going to disallow mixing “literal arrays” and supplied data sources, for this reason. Try putting the data columns in the data source, and then use x=“the_column_name” instead.

Thanks,

Bryan

You 100% can use two plots in tabs from the same data source
(I’ve done it).

It’s probably just a problem with your code as Bryan indicated.

Best,

That seems to be it - for a number of reasons, I had extracted columns to lists…

I’ve rejigged my code and now the X and Y for both point to columns in a source - and it works OK.

For reference, radius is also affected by this - if the two plots use the same source, the radius (if an actual array/list) is the same for both, regardless of what you specify.
This may be more of an issue because of the way bokeh deals with scatter point sizes, but I think thats another issue…

Thanks
