Installation

From source

git clone https://github.com/mosioc/term-plot.git
cd term-plot
pip install -e .

Quick Start

Bar Chart

from term_plot import BarChart

# Simple horizontal bar chart
data = [23, 45, 12, 67, 34, 89, 56]
labels = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']

chart = BarChart(data, labels=labels, title="Daily Sales", width=50)
print(chart.horizontal())

# Vertical bar chart
chart = BarChart(data, labels=labels, title="Daily Sales", height=15)
print(chart.vertical())

Line Chart

from term_plot import LineChart

# Single series
data = [1, 3, 7, 4, 8, 6, 9, 12, 10]
chart = LineChart(data, title="Temperature Over Time", width=60, height=15)
print(chart.plot())

# Multiple series
data = {
    "Product A": [5, 7, 9, 12, 15, 18, 20],
    "Product B": [3, 5, 8, 10, 12, 15, 17]
}
chart = LineChart(data, title="Sales Comparison", width=70, height=20)
print(chart.plot())

Scatter Plot

from term_plot import ScatterPlot

x_data = [1, 2, 3, 4, 5, 6, 7, 8, 9]
y_data = [2, 4, 3, 5, 7, 6, 8, 9, 8]

chart = ScatterPlot(x_data, y_data, title="Correlation Plot", width=50, height=15)
print(chart.plot())

Histogram

from term_plot import Histogram
import random

# Generate sample data
data = [random.gauss(50, 15) for _ in range(1000)]

chart = Histogram(data, bins=15, title="Test Score Distribution", width=60, height=15)
print(chart.plot())

Customization Options

ASCII vs Unicode

# Unicode mode (default) - prettier but requires Unicode support
chart = BarChart(data, labels=labels, use_unicode=True)

# ASCII mode - works everywhere
chart = BarChart(data, labels=labels, use_unicode=False)

Colors

# With colors (default)
chart = BarChart(data, labels=labels, color=True)

# Without colors
chart = BarChart(data, labels=labels, color=False)

Size Control

# Custom width and height
chart = LineChart(data, width=80, height=25)
