Hi,
I’m trying to set colors of a line graph, however I keep getting error which I’m not able to resolve.

I’ve a function which takes in a string and a pandas dataframe:

def plot_metric(app_field, data):

colormap = {'android ': 'red', 'iphone': 'green', 'web_denzel': 'blue', 'all': 'red'}

colors = [colormap[x] for x in data['app']]

p.line('start', 'scaled_impact', source=data[data.app==app_field], color = colors)

I keep getting error:

Following the same example as in the gallery: http://bokeh.pydata.org/en/latest/docs/gallery/iris.html

Any help will be appreciated.

Thanks.
