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.
