The following is the syntax: import matplotlib.pyplot as plt In matplotlib, you can create a scatter plot using the pyplot’s scatter() function. It offers a range of different plots and customizations. Matplotlib is a library in python used for visualizing data. #THIN LINE SCATTER PLOT MATPLOTLIB HOW TO#How to make a scatter plot with Matplotlib? In this tutorial, we’ll look at how to create a scatter plot in python using matplotlib. They’re particularly useful for showing correlations and groupings in data. I hope you find the tutorial useful to start with matplotlib.Scatter plots are great for visualizing data points in two dimensions. After that, we have used the clf() function to clear the plot as follows: In this code, we created a plot and defined labels as well. In the clf() function, we don’t have any arguments. The clf() function of the pyplot clears the plot. Then plt.xlabel() generates a text for x-axis and plt.ylabel() generates a text for y-axis. In the above example, we have regular x and y arrays for x and y coordinates respectively. In the above syntax, labeltext is the text of the label and is a string labelfont describes the font size, weight, family of the label text, and it’s optional. You can create the labels for the x and the y-axis using the xlabel() and ylabel() functions of pyplot. Similarly, to limit y-axis coordinates, you will put the following line of code: plt.ylim() In this example, the points in the x-axis will start from 0 till 160 like this: ()Ĭonsider the example below to set the x-axis limit for the plot: from matplotlib import pyplot as plt You can set the range or limit of the x and y-axis by using the xlim() and ylim() functions of pyplot respectively. This will change the font to 30 the output is going to be: The font in the syntax above is a user-defined dictionary that specifies the weight, font family, font size, etc. To use rc() to change font size, use the syntax below: ('fontname', **font) The rc() function is used to customize the rc settings. We can change the font size of a plot with the help of a function called rc(). Similarly, 2,2,2 means 2 rows, 2 columns, and the plot will be at index 2 of the grid. In this example, 2,2,1 means 2 rows, 2 columns, and the plot will be at index 1. To plot horizontal graphs, change the subplot rows and columns values as: plt.subplot(2, 1, 1) The next step is to create arrays to plot integer points in the graph. Similarly, 1, 2, 2 tells that we have 1 row, 2 columns, but this time the plot at index 2. In the first subplot, 1, 2, 1 states that we have 1 row, 2 columns, and the current plot is going to be plotted at index 1. The first thing is to define the location of the plot. #THIN LINE SCATTER PLOT MATPLOTLIB CODE#Both arrays are merged together with zip() function, iterated through the final array and axhline() plots the lines as shown in the output below:Ĭonsider the following code to get a better understanding of how to plot more than one graph in one figure. The code is the same we have an array of four points of the y-axis and different colors this time. Plt.axvline(p, label='line: '.format(p), c=c) Some other examples of plots in Matplotlib include: We can use the bar() function to make bar charts with a lot of customizations. We can also map the colors and width of the different parameters such as speed time etc. We can use the streamplot() function to plot the streamlines of a vector. To add an arbitrary path in Matplotlib we use matplotlib.path module. To return the bin counts and probabilities in the form of a histogram, we use the function hist(). Similarly, the contour() function does the same job. We can represent a two-dimensional array in color by using the function pcolormesh() even if the dimensions are unevenly spaced. Line PlotĪ line plot is a simple 2D line in the graph. This section briefly explains some plot types in matplotlib. There are a number of different plot types in matplotlib.
