Feature Request: Additional plot function

[busiing]

For my recent project, I am building a matplot.pyplot graph with 3 subplots and a slider function.

First, you see the whole year.

If you click into the slider the x-axis is reduced to a 1-week view (168 timesteps - hourly resolution).

With the function io_plot - the process takes about 1 minute. The frame updating through the slider function takes also some time.

I created a plot function for stacked bar charts with the matplotlib.pyplot function fill_between. (Link to Feature Request

I am working on integrating that function in oemof/visio to speed up the plot function.
But since I am new to programming at all - I could use some help for the styleguide and protect visio from "dirty" code.

Are you open for some help next week in Oldenburg @uvchik?
