Quick Start

Line Chart

import termichart

chart = termichart.PyChart("line")
chart.size(80, 20)
chart.set_title("Sensor Data")
for i in range(15):
    chart.add_point(float(i), 10.0 + i * 1.5 + (i % 3) * 2.0)
chart.show()

Candlestick Chart

import termichart

chart = termichart.PyChart("candlestick")
chart.size(80, 20)
chart.set_title("BTC/USDT")
chart.add_candle(0, 100.0, 110.0, 95.0, 105.0, 1000.0)
chart.add_candle(1, 105.0, 115.0, 100.0, 112.0, 1200.0)
chart.add_candle(2, 112.0, 118.0, 108.0, 110.0, 900.0)
chart.show()

Load from JSON

import termichart

chart = termichart.PyChart("candlestick")
chart.size(80, 20)
json_data = termichart.load_json("data.json")
chart.load_json(json_data)
chart.show()
