We get a line plot connecting the paired data points. Plt.savefig("paired_lineplot_matplotlib_Python.png", Here specify the line of the color to be gray One of the lesser known features (to me :-)) of Matplotlib’s plot function, it can take the two dimensional arrays as input and make a plot. Our arrays are two dimesinonal and they look like thisĪrray(, Let us create numpy arrays with coordinates for X and Y of these paired data points. For example, if we have (x1,y1) and (x2,y2) from the same country for two years, we need to add a line between them. First, let us make a plot without points, but connecting the locations of paired data points with a line. One of the key feature of the plot is to connect two paired data points with lines. Matplotlib Scatterplot colored by variable Plot connecting two coordinates with lines in Matplotlib Plt.savefig("scatterplot_point_colored_by_variable_matplotlib_Python.png", Let us start with scatterplot and color it by the third variable. The key idea here is we have paired data points.
To do that, we aim to connect the data points at one time point with the corresponding data point in the next time point. What we are interested in is understanding how the relationship between two quantitiave variables on the x-and y-axis in the scatter plot changes over time. scatterplot with lines in matplotlib Scatter plot in Matplotlib An example dataset with paired information is same measurements at two time points.ĭf = gapminder.query('year in & continent ="Asia"')Īnd our scatter plot with connected lines would look this “spaghetti”. Here, we will focus on subset of data to create paired data. To make scatterplot with lines connecting paired data points, we will use gapminder data set.
PLOT LINE IN SCATTER PLOT MATPLOTLIB HOW TO
How To Connect Paired Data Points with Lines using Matplotlib in Python? Mainly we use Matplotlib’s plot() function and scatter() function to make scatter plot and add lines to paired data points. Adding lines to paired data points can be extremely helpful in understanding the relationship between two variables with respect to a third variable. In this tutorial, we will learn how to connect paired data points with lines in a scatter plot using Matplotlib in python.
