You could do this with a million different graphics! # Beacuse I'm asking for two rows of three columns each, # I need to separate them out with even MORE parentheses # Using figsize to make the figure a little bigger, 10"x5" fig, (( ax1, ax2, ax3 ), ( ax4, ax5, a圆 )) = plt. set_title ( "Iran" ) # If you don't do tight_layout() you'll have weird overlaps plt. set_title ( "Bhutan" ) # Use ax2 to plot Iran df = 'Iran' ]. subplots ( nrows = 2, ncols = 1, sharex = True, sharey = True ) # Use ax1 to plot Bhutan df = 'Bhutan' ]. ![]() # Receive ax1 and ax2 - note that they go in parens fig, ( ax1, ax2 ) = plt. To make the x and y axes match up, you need to pass sharex and sharey to Iran peaks at around a GDP of $13k Bhutan only gets up to about $6k. If you look at the y-axis labels, you’ll see See how it looks like they’re both making a lot of money in the end? subplots ( nrows = 2, ncols = 1 ) # Use ax1 to plot Bhutan df = 'Bhutan' ]. # Be sure to put them in parenthesis fig, ( ax1, ax2 ) = plt. Note: The next one is nicer than this one because it shares x and y axes. Nrows= and ncols to ask for two rows of graphics, each row having one Line_plot = data.We can receive multiple ax elements from. For theis example we’ll use the Pandas library: import pandas as pd One follow up question we got is on how to add a reference horizontal line to a line plot. # multiple graphs one figureĪx.plot(x,z) Add an horizontal line to a line plot When dealing with more complex multi variable data, we use subplot grids to render multiple graphs. Plt.legend() Multiple line plots in one figure Plt.plot(x,z, marker = '+', color = 'g',label = 'exponential growth') Plt.plot(x,y,marker='.', color='r', label= 'accelerated growth') We also use the label parameter to define the appropriate label legend. In this example we also customize the marker type and line color. We can easily add a legend to the chart using the plt.legend() method as shown below. Plt.plot(x,z) Adding a legend to the chart You might as well use the Matplotlib to generate a simple multi line graph. You can reuse the data DataFrame that you have created in the previous section of this tutorial. You can use the plot() DataFrame method, that is integral to the Pandas library to draw a simple multi-line chart off data in multiple DataFrame columns. Note: We can obviously construct our DataFrame by reading excel, text, json or csv files as well as connecting to databases or data APIs.Īx= sns.lineplot(x='x', y='y', data=data)Īx1 = sns.lineplot(x='x', y='z', data=data) Multiple line charts with Pandas First, we will go ahead and create a DataFrame that we later feed into a couple of lineplot calls, each drawing one plot. We will start by using Seaborn and specifically the lineplot chart. Z = np.exp(x) Seaborn multiple lines chart We’ll use the Numpy library to quickly generate simple x,y coordinate data. ![]() X = Īx.plot(x,z) Importing Data Visualization libraries Use the plot() function to render several lines, as shown below:.Create a matplotlib figure and an axes sub-plot.Gather the data to plot into lists, Numpy arrays, a dictionary or a pandas DataFrame.To create a line plot showing multiple lines with Matplotlib or Seaborn proceed as following: Plot multiple lines with Matplotlib and Seaborn We’ll provide examples leveraging the two popular Python Data Visualization libraries: Seaborn and Matplotlib. Today we’ll learn to draw a bit more sophisticated lineplots that display multiple lines. ![]()
