How to Draw Graph In Sympy?

3 minutes read

To draw a graph in Sympy, you first need to import the necessary modules. Then, define a symbolic variable for the independent variable in your equation. Next, define the function or equation that you want to plot. Finally, use the plot function to create the graph.


For example, if you want to plot the equation y = x^2, you would do the following:

1
2
3
4
5
6
7
8
from sympy import symbols, plot

x = symbols('x')
expr = x**2

p = plot(expr, show=False)
p.title = 'Graph of y = x^2'
p.show()


This will generate a plot of the function y = x^2. You can customize the plot further by adding labels, changing the axis limits, or adding grid lines. Sympy provides a lot of flexibility for creating and customizing graphs, so you can easily create complex plots with just a few lines of code.


What is the difference between a line graph and a scatter plot in sympy?

In Sympy, which is a Python library for symbolic mathematics, line graphs and scatter plots are similar types of visualizations used to represent data but with some key differences:

  1. Line graph: A line graph is used to represent data points that are connected by straight lines. It is used to show the trend or change in data over time or across different categories. In Sympy, a line graph can be created using the plot function, which connects the data points with straight lines.
  2. Scatter plot: A scatter plot is used to represent individual data points without connecting them with lines. It is used to show the relationship or correlation between two variables. In Sympy, a scatter plot can be created using the plot function with the parameter show=False, which plots only the data points without connecting them.


In summary, the main difference between a line graph and a scatter plot in Sympy is that a line graph connects the data points with straight lines to show trends or changes over time, while a scatter plot plots individual data points without connecting them to show relationships or correlations between variables.


How to change the color of the lines on a graph in sympy?

In SymPy, you can change the color of the lines on a graph using the color parameter in the plot function. Here is an example code snippet that demonstrates how to do this:

1
2
3
4
5
6
7
8
9
from sympy import symbols, sin, plot

x = symbols('x')
p1 = plot(sin(x), line_color='blue', show=False)
p2 = plot(2*sin(x), line_color='red', show=False)

p1.extend(p2)  # combine the two plots

p1.show()  # display the plot


In this code snippet, we are plotting the sine function and 2 times the sine function with different line colors. We specify the color of each line using the line_color parameter in the plot function. You can change the color of the lines by passing a different color string to the line_color parameter (e.g., 'red', 'green', 'blue', etc.).


You can also change the line style and line width of the plot by using the line_style and line_width parameters in the plot function, respectively.


What is the main function of a histogram in sympy?

The main function of a histogram in sympy is to represent the distribution of data values in the form of a bar graph. It shows the frequency or probability of different intervals or bins in the data set. This visualization helps in understanding the underlying pattern and shape of the data distribution.
