I need to plot a barchart with dates on X-axis and values on Y-axis. This barchart must show the presence or absence of some factors in a some time. I try to use the "barchart_demo.py" as example, but in my case (X-values are dates in datetime format) this not quite fit.
I want to get something like attached example. Is this possible? Which type of graphs (hist, bar...) and how I need to use?
