In Gnuplot I would have plotted with smooth cplines. Is there an easy way to do this in PyPlot? I've found some tutorials, but they all seem rather complex. You could use scipy.interpolate.spline to smooth out your data yourself: spline is deprecated in scipy 0.19.0, use BSpline class instead.

Oct 17, 2016 · So with the code below I can plot a figure with 3 lines, but they are angular. Is it possible to smooth the lines? import matplotlib.pyplot as plt import pandas as pd # Dataframe consist of 3 c...

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.

I'd recommend using scipy.optimize.curve_fit(). It lets you specify your own fitting function which contains parameters and it'll fit the parameters for you: return a * np.exp(-b * x) + c.

Apr 15, 2023 · Uncover hidden insights in your data with these 4 methods for smoothing a line. From rolling windows to spline interpolation, we'll reveal the secrets you need to know to unlock the full potential of your data.

Nov 6, 2024 · Below, we will delve into seven effective methods to smooth lines in your PyPlot graphs, each with practical examples and variations. Method 1: Smoothing with Gaussian Filter. One straightforward way to enhance the smoothness of your line is by using the Gaussian filter provided by scipy. This method is effective for data that may not be ...

The simplest way as I know so far is, use QGIS Raster>Projections>Warp(reproject), then you can specify the "resampling method to use" as "Cubic Spline", and output resolution in smaller units, which could interpolate the raster data very smoothly. See the result below:

Mar 15, 2021 · In this article, we will be plotting a scatter plot with the smooth line with the help of the SciPy library. To plot a smooth line scatter plot we use the following function: scipy.interpolate.make_interp_spline () from the SciPy library computes the coefficients of interpolating B-spline.

Mar 8, 2017 · My question is how I can make it smoother/straighter with less points and curves. Note: I've tried using simplify api from Shapely, but no luck. Update: I'm actually creating a given line from polygon (using CenterLine python lib), and polygon is created using rasterio.features.shapes method which reads this bitmap. Code:

Apr 4, 2019 · You don't need a buffer; the example you linked to is just using a buffer to create a polygon from a point. You can simplify your polygon/polyline directly. This solution worked for me. Just adjust the buffer amount to work with your units. Solution copied here:
