A fluent wrapper around matplotlib for easy, expressive visualizations

Viz - A Fluent API Wrapper for Matplotlib

Viz is a user-friendly, fluent API wrapper for matplotlib designed to streamline the process of creating, customizing, and managing plots in Python. By supporting method chaining and reusable functions, Viz makes complex plotting workflows easier to handle, while still offering complete control over matplotlib functionalities.

🚀 Quick Start

Here’s how you can use Viz to create a simple plot:

import matplotlib.pyplot as plt
from mplviz import Viz

# Create a figure and axis
fig, ax = plt.subplots()

# Initialize Viz with the axis
viz = Viz(ax, fig)

# Plot a line with customization
viz.plot([1, 2, 3], [4, 5, 6], label='Line') \
   .set_title("My Plot") \
   .xlabel("X Axis") \
   .ylabel("Y Axis") \
   .legend() \
   .grid(True) \
   .show()

Key Features

• Method Chaining: Easily create readable and customizable plots with fluent syntax.
• Support for Multiple Plot Types: Create line, scatter, bar charts, and more.
• Grid and Axis Customization: Customize axis labels, grid visibility, and other settings.
• Flexible Subplot Layout: Seamlessly create grid-based layouts with subplots.
• Save and Export: Save plots to images or PDFs.
• Reusability & Extensibility: Define reusable styles and settings for plots.

---

Supported Plot Types

• Line Plot: viz.plot()
• Scatter Plot: viz.scatter()
• Bar Chart: viz.bar()
• Contour Plot: viz.contour()
• Heatmaps/Images: viz.imshow()
• Annotations: viz.annotate()
• Axis Customization: viz.grid(), viz.set_xlim(), viz.set_ylim()
• Subplots Layout: viz.add_subplot()
• Multiple Y-Axes: viz.twinx()

---

Method Overview

Basic Plotting

• viz.plot(x, y, **kwargs) - Create a line plot.
• viz.scatter(x, y, **kwargs) - Create a scatter plot.
• viz.bar(x, y, **kwargs) - Create a bar chart.

Customization

• viz.set_title(title, **kwargs) - Set the plot title.
• viz.xlabel(text, **kwargs) - Set the x-axis label.
• viz.ylabel(text, **kwargs) - Set the y-axis label.
• viz.grid(flag=True, **kwargs) - Toggle grid lines on or off.
• viz.legend(**kwargs) - Show the legend.

Layout and Saving

• viz.show(clear=False) - Display the plot in the notebook.
• viz.tight_layout(**kwargs) - Adjust subplot layout to prevent overlap.
• viz.save(path, **kwargs) - Save the plot to a file.

Combine Multiple Plots

Combine multiple Viz objects into a single figure with subplots for side-by-side comparisons.

fig, axs = plt.subplots(2, 2, figsize=(10, 10))
viz1 = Viz(axs[0, 0])
viz2 = Viz(axs[0, 1])

viz1.plot([1, 2, 3], [4, 5, 6]).set_title("Plot 1")
viz2.scatter([1, 2, 3], [2, 3, 4]).set_title("Plot 2")

combined_viz = Viz.combine_viz([viz1, viz2])
combined_viz.show()

---

Customization and Style

You can apply predefined matplotlib styles using plt.style for quick and consistent styling:

viz.style('seaborn-darkgrid')
