Matplotlib pcolormesh: X, Y, C Shapes and Shading
Use Matplotlib pcolormesh for 2D grids with correct X, Y, C dimensions, shading modes, colorbars, and uneven coordinate spacing.
Matplotlib
Learn Matplotlib with tutorials for plots, labels, grids, colors, figures, legends, annotations, exports, and visualization examples in Python.
Matplotlib tight_layout(): Fix Clipped Labels and Spacing
Make Matplotlib subplot spacing deliberate with tight_layout(), then inspect the saved figure for labels, legends, titles, and annotations.
Clear a Matplotlib Plot: cla(), clf(), clear(), and close()
Clear Matplotlib axes and figures with ax.clear(), fig.clear(), plt.cla(), plt.clf(), and plt.close() without leaking plot resources.
Matplotlib Grid Lines: Major, Minor, Styling, and axisbelow
Use Matplotlib grid lines to support reading values, with deliberate major or minor ticks, axis selection, styling, and layering.
Matplotlib Pie Chart: Percentages, Labels, Donuts, and Alternatives
Create readable Matplotlib pie charts with labels, percentages, explode, donut wedges, legends, equal aspect, and better chart alternatives.
Matplotlib Linestyle: Solid, Dashed, Dotted, and Custom Lines
Use Matplotlib line patterns, weight, transparency, color, and markers together so plotted series remain clear after export and printing.
Matplotlib Boxplot: Customize Box and Whisker Plots
Learn Matplotlib boxplot customization in Python, including labels, colors, notches, horizontal plots, whiskers, outliers, means, and figure sizing.
Matplotlib ylim(): Set and Read Y-Axis Limits
Use Matplotlib ylim to set y-axis limits, inspect current bounds, preserve automatic scaling, and avoid hiding data with restrictive chart ranges.
Matplotlib Log Scale: log, symlog, Ticks, and Positive Data
Make Matplotlib log charts honest by matching the transform to the data domain and labeling the base, limits, ticks, and invalid values.
Matplotlib xticks: Set X-Axis Tick Positions
Control Matplotlib x-axis tick positions, labels, rotation, intervals, date ticks, and locator behavior with clear Axes examples.
