How to build a live bokeh plot that adds the real time data element to the existing plot

I have real time data from a Electrical SCADA system where at every minute current sample of data from each data point will be written into database. (so it’s a live data).
I want to plot a bokeh plot that keeps on adding the new sample of data to the plot as it arrives.
How can I do that?. Sample code will be appreciated.

Thank you…
