Webb14 jan. 2024 · When we plot a dataset such as a histogram, the shape of that charted plot is what we call its distribution. The most commonly observed shape of continuous values is the bell curve, also called the Gaussian or normal distribution. It is named after the German mathematician Carl Friedrich Gauss. WebbIn order to plot the histogram, we will use the matplotlib function bar (), while the fitting function will be plotted using the classical plot () function. The final result is displayed in Figure 2: Figure 2 Summary In these two examples, the curve_fit () function was used to apply to different exponential fits to specific data points.
