真香,Python “手绘风格”数据可视化方法汇总

大家好,今天给大家带来绘制“手绘风格”可视化作品的小技巧,主要涉及Python编码绘制。主要内容如下:

  • Python-matplotlib 手绘风格图表绘制
  • Python-cutecharts 手绘风格图表绘制
  • Python-py-roughviz 手绘风格图表绘制

Python-matplotlib 手绘风格图表绘制

使用Python进行可视化绘制,首先想到的当然是Matplotlib,“手绘风格”的图表绘制方法当然首选它。在Matplotlib中,matplotlib.pyplot.xkcd() 绘图函数就可以进行手绘风图表的绘制,下面小编通过具体样例进行展示:

  • 样例一:
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

with plt.xkcd():
    fig, ax = plt.subplots(figsize=(6.5,4),dpi=100)
    ax = df.plot.bar(color=["#BC3C28","#0972B5"],ec="black",rot=15,ax=ax)
    ax.set_ylim((0,100))
    ax.legend(frameon=False)
    ax.set_title("EXAMPLE01 OF MATPLOTLIB.XKCD()",pad=20)
    ax.text(.8,-.22,'Visualization by DataCharm',transform = ax.transAxes,
            ha='center', va='center',fontsize =10,color='black')

  • 样例二:
df = pd.DataFrame({'x':[1,2,2.5,3,3.5,4,5],'y':[4,4,4.5,5,5.5,6,6],})with plt.xkcd():
    fig, ax = plt.subplots(figsize=(6.5,4),dpi=100)
    ax = df.plot.kde(color=["#BC3C28","#0972B5"],ax=ax)
    ax.set_ylim((0,0.4))
    ax.legend(frameon=False)
    ax.set_title("EXAMPLE02 OF MATPLOTLIB.XKCD()",pad=20)
    ax.text(.8,-.22,'Visualization by DataCharm',transform = ax.transAxes,
            ha='center', va='center',fontsize =10,color='black')

  • 样例三:
with plt.xkcd():
    fig, ax = plt.subplots(figsize=(6.5,4),dpi=100)
    ax.spines["right"].set_color('none')
    ax.spines["top"].set_color('none')
    ax.set_xticks([])
    ax.set_yticks([])
    ax.set_ylim([-30,10])
    data = np.ones(100)
    data[70:]-= np.arange(30)
    ax.annotate('THE DAY I REALIZED\nI COULD COOK BACON\nWHENEVER I WANTED',
        xy=(70,1), arrowprops=dict(arrowstyle='->'), xytext=(15,-10))

    ax.plot(data,color="#BC3C28")

    ax.set_xlabel('time')
    ax.set_ylabel('my overall health')
    ax.set_title("EXAMPLE03 OF MATPLOTLIB.XKCD()")
    ax.text(.8,-.15,'Visualization by DataCharm',transform = ax.transAxes,
            ha='center', va='center',fontsize =10,color='black')

Python-cutecharts 手绘风格图表绘制

介绍完使用matplotlib绘制后,小编再介绍一个专门绘制“手绘风格”图表的Python可视化库-cutecharts。这个包可能有的小伙伴也有了解过,如果熟悉pyecharts的同学肯定会更加快速上手的。官网如下:https://github.com/cutecharts/cutecharts.py 。这里小编就直接列举几个例子,感兴趣的同学可自行探索哈~

  • 样例一:
from cutecharts.charts import Bar
from cutecharts.components import Page
from cutecharts.faker import Faker

defbar_base()-> Bar:
    chart = Bar("Bar-cutecharts基本示例01")
    chart.set_options(labels=Faker.choose(), x_label="I'm xlabel", y_label="I'm ylabel")
    chart.add_series("series-A", Faker.values())return chart

bar_base().render_notebook()

注:render_notebook()方法可使绘图结果在jupyter notebook 中显示。图片

  • 样例二:
from cutecharts.charts import Line
from cutecharts.components import Page
from cutecharts.faker import Faker

defline_base()-> Line:
    chart = Line("Line-cutecharts基本示例02")
    chart.set_options(labels=Faker.choose(), x_label="I'm xlabel", y_label="I'm ylabel")
    chart.add_series("series-A", Faker.values())
    chart.add_series("series-B", Faker.values())return chart
line_base().render_notebook()

  • 样例三:
from cutecharts.charts import Pie
from cutecharts.components import Page
from cutecharts.faker import Faker

defpie_base()-> Pie:
    chart = Pie("Pie-cutecharts基本示例03")
    chart.set_options(labels=Faker.choose(),legend_pos="upRight")
    chart.add_series(Faker.values())return chart

pie_base().render_notebook()

这里这是基本的图表绘制,实现定制化的属性参数也都没有介绍,小伙伴们可去官网查阅(由于没详细的官方文档,大家可参考样例和pyecharts的文档)

Python-py-roughviz 手绘风格图表绘制

这个和cutecharts包一样,都是基于roughViz.js转换编码绘制的,官网为:https://github.com/charlesdong1991/py-roughviz 。由于所支持的图表类型不是很多且各个图标设置的参数也不够完善,这里小编直接给出两个样例,感兴趣的小伙伴可自行探索哈~

  • 样例一:
from roughviz.charts.bar import Bar
data ={"labels":["North","South","East","West"],"values":[10,5,8,3]}

bar = Bar(data=data, title="Bar-roughviz基本示例01", title_fontsize=3)
bar.set_options(xlabel="Region", ylabel="Number", color="orange")
bar.show()

Example01 of roughviz

  • 样例二:
from roughviz.charts.donut import Donut
donut = Donut(data={"labels":['a','b'],"values":[10,20]}, title="Donut-roughviz基本示例02", title_fontsize=3)
donut.show()
