To create beautiful bokeh shots, make sure you also illuminate your subject adequately. sin ( x ) source = ColumnDataSource ( data = dict ( x = x, y = y )) # Set up plot plot = figure ( plot_height = 400, plot_width = 400, title = "my sine wave", tools = "crosshair,pan,reset,save,wheel_zoom", x_range =, y_range = ) plot. For good Bokeh, ideally points and lines would blur smoothly as they fell out of focus, in the manner, for example, of a smooth Gaussian blurring. To make the bokeh even larger, use a small f-number like f/1.8. The farther away the lights are, the softer the effect will be.
