I am trying to plot a basic barchart but I keep seeing an error called 'StopIteration'. I am following an example, and the code seems fine:
amount = bugrlary_dict.values() months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"] print len(amount) print len(months) bar = Bar(amount, months, filename="bar.html") bar.title("Bar Chart of the Amount of Burglaries").xlabel("Months").ylabel("Amount") bar.show() UPDATE this answer is out of date and will not work with Bokeh versions newer than 0.10
Please refer to recent documentation
You're passing invalid input. From the doc:
(dict, OrderedDict, lists, arrays and DataFrames are valid inputs)
This is the example they have on there:
from collections import OrderedDict from bokeh.charts import Bar, output_file, show # (dict, OrderedDict, lists, arrays and DataFrames are valid inputs) xyvalues = OrderedDict() xyvalues['python']=[-2, 5] xyvalues['pypy']=[12, 40] xyvalues['jython']=[22, 30] cat = ['1st', '2nd'] bar = Bar(xyvalues, cat, title="Stacked bars", xlabel="category", ylabel="language") output_file("stacked_bar.html") show(bar) Your amount is a dict_values() which will not be accepted. I'm not sure what your bugrlary_dict is but have that as the data for the Bar() and I'm assuming your months is the label. That should work assuming len(bugrlary_dict) == 12
Output from Bokeh's example:
In Bokeh 0.12.5, you can do it the following way:
from bokeh.charts import Bar, output_file, show # best support is with data in a format that is table-like data = { 'sample': ['1st', '2nd', '1st', '2nd', '1st', '2nd'], 'interpreter': ['python', 'python', 'pypy', 'pypy', 'jython', 'jython'], 'timing': [-2, 5, 12, 40, 22, 30] } # x-axis labels pulled from the interpreter column, grouping labels from sample column bar = Bar(data, values='timing', label='sample', group='interpreter', title="Python Interpreter Sampling - Grouped Bar chart", legend='top_left', plot_width=400, xlabel="Category", ylabel="Language") output_file("grouped_bar.html") show(bar) Output:
Change the parameter in Bar() from group to stack if you want a stacked bar chart
