The matplotlib.rcparams is a dictionary-like variable that has all the configuration settings to customize default parameters. In the above example, the parameters passed to the matplotlib vline() function draws a vertical line accordingly. To create a scatter plot with a legend one may use a loop and create one scatter plot per item to appear in the legend and set the label accordingly. The label height is full or partial height as desired. Increase the thickness of a line with Matplotlib. string, it should be one of the available arrowstyle names, with Figures are identified via a figure number that is passed to figure. in this example: matplotlib.axes.Axes.errorbar / matplotlib.pyplot.errorbar, Download Python source code: errorbar_limits_simple.py, Download Jupyter notebook: errorbar_limits_simple.ipynb.
