basic_plot

A scatter plot of a smooth periodic oscillation. This example demonstrates red circle scatter markers with black outlines, using the low-level bokeh.models API.

Details

Bokeh APIs:

bokeh.models.Circle, bokeh.models.Plot, bokeh.models.ColumnDataSource, bokeh.models.LinearAxis, bokeh.models.PanTool, bokeh.models.WheelZoomTool
