Aug 13, 2024 · In this article, we will learn about line charts and matplotlib simple line plots in Python. Here, we will see some of the examples of a line chart in Python using Matplotlib: In this example, a simple line chart is generated using NumPy to define data values.

PyPlot doesn't have any built-in support for this, but you can easily implement some basic curve-fitting yourself, like the code seen here, or if you're using GuiQwt it has a curve fitting module. (You could probably also steal the code from SciPy to do this as well).

Apr 2, 2025 · To plot a smooth curve, we first fit a spline curve to the curve and use the curve to find the y-values for x values separated by an infinitesimally small gap. We can get a smooth curve by plotting those points with a very infinitesimally small gap.

May 2, 2015 · There is a cool (at least for me) way to draw curve lines between two points, using Bezier curves. Just with some simple code you can create lists with dots connecting points and chart them with matplotlib, for example:

Create a basic line plot. import matplotlib.pyplot as plt import numpy as np # Data for plotting t = np . arange ( 0.0 , 2.0 , 0.01 ) s = 1 + np . sin ( 2 * np . pi * t ) fig , ax = plt . subplots () ax . plot ( t , s ) ax . set ( xlabel = 'time (s)' , ylabel = 'voltage (mV)' , title = …

Sep 7, 2020 · Often you may want to plot a smooth curve in Matplotlib for a line chart. Fortunately this is easy to do with the help of the following SciPy functions: scipy.interpolate.make_interp_spline()

Apr 7, 2016 · I cannot find a way to draw an arbitrary line with matplotlib Python library. It allows to draw horizontal and vertical lines (with matplotlib.pyplot.axhline and matplotlib.pyplot.axvline , for example), but i do not see how to draw a line through two given points (x1, y1) and (x2, y2) .

Do you want to create a wiggly curve instead? In this article, we will explore how to use the make_interp_spline() and BSpline() functions from scipy.interpolate to create a smooth curve in matplotlib.

Curved line. The plot() method also works for other types of line charts. It doesn’t need to be a straight line, y can have any type of values.

Line chart with Matplotlib. Matplotlib is a great fit to build line charts thanks to its plot() function. The first chart of this section explains how to use plot() from any kind of data input format. The next one goes deep into chart customization (line width, color aspect and more).
