Sample Charts

• default dark theme

• default light theme

• mono theme

Quick Start

• installation

pip install natal

• generate a chart

from natal import Data, Chart

# create chart data object
mimi = Data(
  name = "MiMi",
  city = "Taipei",
  dt = "1980-04-20 14:30"
)

# return natal chart in SVG string
Chart(mimi, width=600).svg

# create transit data object
current = Data(
  name = "Current",
  city = "Taipei",
  dt = datetime.now()
)

# create a transit chart
transit_chart = Chart(
    data1=mimi, 
    data2=current, 
    width=600
)

# view the composite chart in jupyter notebook
from IPython.display import HTML

HTML(transit_chart.svg)

following SVG chart will be produced:

Stats

• statistics of Data object in tabular form

from natal import Data, Stats

mimi = Data(
    name = "MiMi",
    city = "Taipei",
    dt = "1980-04-20 14:30"
)

transit = Data(
    name = "Transit",
    city = "Taipei",
    dt = "2024-10-10 12:00"
)

stats = Stats(data1=mimi, data2=transit)

print(stats.full_report("ascii"))

• following ascii report will be created
• Note: fonts with double space char support is suggested for better ascii table display eg. Sarasa Mono TC
