Advanced examples

Here's a list of cool uses for dayplot to demonstrate its capabilities. It regularly uses external libraries such as pyfonts or pypalettes.

Average temperature in Tunis

The dataset can be found here.

from pyfonts import load_font
import dayplot as dp


df = pd.read_csv("city_temperature.csv", low_memory=False)

df = df[df["Year"].isin([2017, 2018, 2019])]
df["Date"] = pd.to_datetime(df[["Year", "Month", "Day"]])
df = df[df["AvgTemperature"] != -99.0]

cmap = load_cmap("jazz_city", cmap_type="continuous", reverse=True)
font_url = "https://github.com/coreyhu/Urbanist/blob/main/fonts/ttf"
fontlight = load_font(f"{font_url}/Urbanist-Light.ttf?raw=true")
fontmedium = load_font(f"{font_url}/Urbanist-Medium.ttf?raw=true")

style_args = dict(
    cmap=cmap,
    day_kws={"font": fontlight},
    month_kws={"font": fontlight},
    day_x_margin=0.03,
    month_y_margin=0.5,
