Now, from the above graph we are able to compare two subject marks of a particular class.

Lets see the sample code on how to compare two different datasets. Scatter plot can also contain more than one dataset in the graph. Though the values are randomly distributed, we can see many data points are mostly on the scale 10 on the x axis and 20 on the y axis as we have provided those values in the mean place. The scatter plot can contain more than 100 values also and we can also see that the spread of the y axis is wider than the x axis. Code to implement scatter plot for randomly distributed data: #importing library The first array in the data set will have the mean set to 10 with a standard deviation of 2 and the second array in the dataset will have the mean set to 20 with a standard deviation of 5. Now, let’s see a sample where there are two arrays filled with 100 random numbers using a normal data distribution. The dataset can contain ‘n’ number of values and the dataset can also contain randomly generated values. Scatter plot for Randomly Distributed Data Each and every dot in the plot is the representation of each student’s scores. Here the x-axis represents the students id and the y-axis represents the students marks. Now, let’s create a simple and basic scatter with two arrays Code of a simple scatter plot: #importing library Once the scatter() function is called, it reads the data and generates a scatter plot. The scatter() function in matplotlib helps the users to create scatter plots. By default their value will be assigned to none. 0 represents transparent and 1 represents opaque.Īll the parameters in the syntax are optional except the xaxis_data and yaxis_data. Transparency value which lies between 0 and 1. The marker size and it can be scalar or equal to the size of x or y array. (xaxis_data, yaxis_data, s = None, c = None, marker = None, cmap = None, vmin = None, vmax = None, alpha = None, linewidths = None, edgecolors = None) Parameter The scatter plot also indicates how the changes in one variable affects the other. We use the scatter() function from matplotlib library to draw a scatter plot.
The dots in the graph represent the relationship between the dataset. Scatter plots are generally used to observe the relationship between the variables. To build a scatter plot, we require two sets of data where one set of arrays represents the x axis and the other set of arrays represents the y axis data. To represent a scatter plot, we will use the matplotlib library.
The dots in the plot are the data values.
Scatter plot in Python is one type of a graph plotted by dots in it.
