How to do it...

The following code block plots five error bar plots in the same grid, and uses constrained layout to ensure proper alignment and appropriate spacing between the plots so that there are no overlaps on labels or ticks:

1. Define the figure and size, and set a constrained layout, then set the style to be used for this session:

fig = plt.figure(figsize=(8,8), constrained_layout=True)plt.style.use('bmh')

2. Define the function to plot an error bar graph:

def plot_errorbar(ax, x, y, xerr=None, yerr=None, errevery=1,                    title=None, xlabel=None, ylabel=None, fmt=None):    ax.errorbar(x, y, xerr=xerr, yerr=yerr, errorevery=errevery, fmt=fmt)    ax.set(title=title, xlabel=xlabel, ylabel=ylabel)

3. Define the data for an exponential curve:

x = ...
