For simplicity, let’s set the number of bins to 10. We can see outliers, clusters of data points, different volume of data points between series; all things that summary statistics can hide. That's a well known problem for scientists and engineers and the only way out is to use a ruler and read the values off the plot. The faceting is defined by a categorical variable or variables. In this post I have added example codes and a short explanation on how to draw line plots using latex. One is to use the default colors and "resetting" the order, which is shown here. When plotting measurement data instead of mathematical functions, scientists usually draw little symbols at the data points, like crosses and squares. The data need to come in the form of ordered pairs \((X_i, Y_i)\), and those pairs are plotted in a set of Cartesian axes. An example of using ODEINT is with the following differential equation with parameter k=0. You may have noticed on the plot of faithful there seems to be two clusters in the data. Add labels to scatter plot data points When creating a scatter graph with a relatively small number of data points, you may wish to label the points by name to make your visual better understandable. The fence separates points in the fence from points outside. I know that xytext=(30,0) goes along with the textcoords, you use those 30,0 values to position the data label point, so its on the 0 y axis and 30 over on the x axis on its own little area. interpolate is a convenient method to create a function based on fixed data points, which can be evaluated anywhere within the domain defined by the given data using linear interpolation. In the following example, we generate a random continuous data of 1000 entries and plot it against its frequency with the data divided into 10 equal strata.
