![]() Now we will be grabbing a real csv file of bitcoin prices from here and then create a time series plot from that CSV file in Python using Matplotlib. Plotting time series data in Python from a CSV FileĬurrently, we were using hard-fed example data to plot the time series. # plot_time_series.pyĭate_format = mpl_dates.DateFormatter('%d-%m-%Y') So, I will be using to format the date in DD-MM-YYYY and then pass it to set_major_formatter() method of (). We will be passing a python format string, as we would have passed to strftime to format the date in our time series plot. We will be formatting the date in our time series plot by using dates from matplotlib. ![]() # plot_time_series.pyįormatting dates in Time Series plots in Matplotlib using Python So, we can also change the alignment of the dates on x-axis of time series plot by using autofmt_xdate() on plt.gcf(). Sometimes, we are working with a lot of dates and showing them horizontally won’t be a good idea in that case. Plt.plot_date(dates, y, linestyle ='solid') If we want to create a line plot instead of the scatter plot, we will have to set linestyle=’solid’ in plt.plot_date(). This will create a simple scatter plot for the time series data.Ĭreating a line plot from time series data in Python Matplotlib Finally, we will be passing dates and values to plt.plot_date() method and call plt.show() to plot. We will be using seaborn style to create scatter plot of the time series data. So, let us create a python file called ‘plot_time_series.py’ and make necessary imports. We will be using Python’s built-in module called datetime(datetime, timedelta) for parsing the dates. If True, the y-axis will be interpreted as Matplotlib dates.Ĭreating a scatter plot from time series data in Python Matplotlibįirst of all, we will create a scatter plot of dates and values in Matplotlib using plt.plot_date(). If True, the x-axis will be interpreted as Matplotlib dates. For details, see the corresponding parameter in plot. If xdate or ydate is True, the respective values x or y are interpreted as Matplotlib dates. The parameters of _date() are shown in the table below:- # ![]() _date(x, y, fmt='o', tz=None, xdate=True, ydate=False, *, data=None, **kwargs)Īnd it returns a list of Line2D objects representing the plotted data. We will use Pandas Dataframe to extract the time series data from a CSV file using pandas.read_csv(). In this tutorial we will learn to create a scatter plot of time series data in Python using _date(). Table of Contents Plot Time Series data in Python using Matplotlib ![]()
