Bokeh server app: Line graph

Community Support
1

Dear all,

I am making a bokeh server app similar to the following example:

https://demo.bokehplots.com/apps/stocks

I am able to make the app which updates data with changes in the widget. However, I am not able to change the colour and line width of a line graph. The code for the graph is shown below. Could anyone please let me know how to change colour and line width of the line graph? After adding line_width and color command, the graph doesn’t appear.

source = ColumnDataSource(data=dict(x=time_step,y=load,l=[2],c=["blue"]))
load_graph = Figure(plot_height=500, plot_width=600, title="Demand")
load_graph.line('x','y',source=source,line_width ='l', color='c')



Regards,

Sundar.

Sundar,

You need to change the properties of the glyph itself, see:

  Appearance — Bokeh 3.3.2 Documentation

Thanks,

Bryan
