  • Timelapse data can be visualised as a line plot ( geom_line) with years on x axis and counts on the y axis. (p9.ggplot(data=yearly_counts, mapping=p9.aes(x='year', y='counts')) + p9.geom_line() ) Unfortunately this does not work, because we plot data for all the species together.

  • After creating three random time series, we defined one Figure (fig) containing one Axes (a plot, ax). We call methods of ax directly to create a stacked area chart and to add a legend, title, and y-axis label. Under the object-oriented approach, it’s clear that all of these are attributes of ax. We present an open-source Python package to help characterize predicted and observed hydrologic time series data called hydrostats which has three main capabilities: Data storage and retrieval based on the Python Data Analysis Library (pandas), visualization and plotting routines using Matplotlib, and a metrics library that currently
