Plot several lines in bokeh applet

I want to extend the sliders applet example of the bokeh-website.

How can I "freeze" the current setting of the line and draw a new line in the same plot?

I am thinking in introducing option-boxes to change between the lines further down the road but so far I can't even get several (static) lines into the same "line" object.

If anyone knows some more documentation about the "bokeh widgets" that would be great, too.

In the callback (in this case, input_change) you can do whatever you like, including creating new ColumnDataSource objects, or calling new render functions like line. Another option would be to start with a single multi_line renderer in the setup step. For this renderer, the data stored in the ColumnDataSource is a not just a list of numbers, it is a "list of lists of numbers". So every update you could append a new sublist of x and y values to the existing data source.

If you'd actually like help iterating on a real example, I encourage you to visit the Bokeh mailing list or GH issue tracker where you can have more of a back and forth exchange with Bokeh devs.
