Aug 14, 2019 · To plot the delta under the curve, just pair up your data points one at a time and then plot it. For instance. x_data=[1,4,6] y_data=[2,3,7] delta_to_plot_x=[1,4,4,6,6] delta_to_plot_y=[2,2,3,3,7] and this function should work at generating the right values.

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:

May 29, 2019 · I have two curves for past data eg. I have cumulative curves for 2013 and for 2014. How to calculate the delta difference between these two curves and propagate this delta difference to the future curves for 2015, 2016, 2017...?

Apr 17, 2025 · Matplotlib is a Python library that can be used for plotting graphs and figures. Plotting multiplots or multiple plots are often required either for comparing the two curves or show some gradual changes in the multiple plots, and this can be done using Subplots.

Jul 30, 2024 · Matplotlib Fill Between is a powerful feature in the Matplotlib library that allows you to fill the area between two curves or lines on a plot. This technique is particularly useful for visualizing data ranges, confidence intervals, and highlighting specific regions of …

Oct 21, 2019 · I have these two curves. How could I plot a segment (and the number) whitch rapresent the distance between them (5 in this case) in the same graph? import matplotlib.pyplot as plt X_ev = [0, 1, 2, 3] Y1_ev = [10, 15, 20, 25] Y2_ev = [2, 10, 10, 15] plt.plot(X_ev,Y1_ev, 'g', label='Curve 1') plt.plot(X_ev,Y2_ev, 'r', label='Curve 2') plt.legend ...

In our call of scipy.optimize.curve_fit() we return two variables: popt and pcov. According to the documentation , popt is a 1D array that contains the optimized fitted parameters and pcov is a 2D array that contains the variances and covariances of the fitted parameters.

In this series of blog posts, I will show you: (1) how to fit curves, with both linear and exponential examples and extract the fitting parameters with errors, and (2) how to fit a single and overlapping peaks in a spectra. These basic fitting skills are extremely powerful and will allow you to extract the most information out of your data.

To draw a curve connecting two points instead of a straight line in matplotlib, we can take the following steps − Set the figure size and adjust the padding between and around the subplots. Define a draw_curve() method to make a curve with a mathematical expression.

The `fill_between` function in Matplotlib is used for adding shaded areas between two curves. This feature is particularly useful for highlighting regions of interest, illustrating confidence intervals, or visualizing areas under curves.
