Matplotlib scatter label points1/22/2024 ![]() This way, we can use the plot to visually depict a third variable or category. ![]() Use the scatter function in Matplotlib and the c parameter to pass in the x and y data and a list of colours to produce a scatter plot. Moreover, the user may add labels, captions, and legends to the plot to offer context and details about the data. We can learn more about the connections between variables and spot any intriguing trends or patterns by examining the plot that results. The colour of each marker in a scatter plot is specified by the c parameter of Matplotlib's scatter function. Depending on how the user wishes to relate the colours to the data, it can take various forms. The scatter plot's markers will all have the same colour if the c parameter is passed a single-colour string or a tuple of RGBA values. For instance, a scatter plot with blue markers would be produced if c='blue' or c=(0.0, 0.0, 1.0, 1.0). ![]() Syntax import matplotlib.pyplot as pltÄata that will be plotted on the x and y axes are denoted by the letters x and y. c parameter defines the marker's shade of colour. The cmap argument can map this to a colormap as a single colour, a series of colours, or a series of values. In this example, we create a scatter plot with several colours. We supply a colour for each point in the colours list and the coordinates for each point in the x and y lists. These lists are then passed to the scatter() method, where the colour for each point is specified by setting c=colors. Plt.title('Scatter plot with Multiple Colours!') # Create a scatter plot with multiple colors Lastly, we display the plot using plt.show() and add labels and a title using plt.xlabel(), plt.ylabel(), and plt.title(). In this example, we use Matplotlib to make a scatter plot with many colours. We import Matplotlib and NumPy, two required libraries. Then, we use the NumPy rand function to produce some random x and y data and a list of random colours for each point in the scatter plot. ![]() The scatter function is then used to construct a scatter plot with various colours using the x, y, and c parameters. The c option specifies the list of colours to be used for each point. The mapping between the colour values and their associated values is then displayed by adding a colour bar using the color bar function. This can help decipher the significance of the colours used in the story. Lastly, we use the xlabel, ylabel, and title methods to add labels and a title to the plot. This can aid in supplying context and details about the data that is being plotted. ![]()
