1 說明：

=====

1.1 Toyplot是一個Python的交互式繪圖庫，可用于數據可視化、繪圖、文字，用各種形式展示。

1.2 為科學家和工程師們提供簡潔的界面。

1.3 可開發美麗的交互式動畫，以滿足電子出版和支持repoducibility的獨特功能。

1.4 創建最佳的數據圖形"out-of-the-box"。

2 準備：

=====

2.1 官網：

https://github.com/sandialabs/toyplot
https://toyplot.readthedocs.io/en/stable/

2.2 安裝：

pip install toyplot
#本機安裝
sudo pip3.8 install toyplot
#推薦國內源安裝

2.3 環境：

華為筆記本電腦、深度deepin-linux操作系統、谷歌瀏覽器、python3.8和微軟vscode編輯器。

3 折線圖：

=======

3.1 本代碼：為注釋版

#line==折線圖
import toyplot as tp

x=['1','2','3','4','5','6']

#y=[31,22,55,41,66,17]  #1組數據

y=[[31,22],[22,17],[55,34],[41,28],[66,43],[17,36]] #2組數據

canvas = tp.Canvas(width=300, height=300,) #方法一，畫布大小設置
#方法二：style=類似與css設置
#canvas = tp.Canvas("6in", "6in", style={"background-color":"pink"})

#坐標軸axes的標簽名
axes = canvas.cartesian(xlabel='序號',ylabel='data')
#線條顏色color設置
#mark = axes.plot(x, y,color='red')  #1組顏色設置

mark = axes.plot(x, y,color=['red','green'])  #1組顏色設置

#水平圖例==horizontal-legends
markers = [mark + tp.marker.create(shape="o") for mark in mark.markers]
axes.label.text = markers[0] + "  dog  " + markers[1] + "  pig"

4 散點圖：

========

4.1 代碼：

import toyplot

canvas = toyplot.Canvas(width=500, height=500)
axes = canvas.cartesian()
m0 = axes.scatterplot([0, 1, 2], [0, 1, 2], size=25)
m1 = axes.text([0, 1, 2], [0, 1, 2], ["0", "55", "100"], color="red")

marks = []
for label in ["0", "55", "100"]:
    marks.Append(toyplot.marker.create(
        shape="o",
        label=label,
        size=25,
    ))
m2 = axes.scatterplot([0, 1, 2], [1, 2, 3], marker=marks)

8.1 代碼：

#散點動畫圖
import numpy
x = numpy.random.normal(size=100)
y = numpy.random.normal(size=len(x))

import toyplot
canvas = toyplot.Canvas(300, 300)
axes = canvas.cartesian()
mark = axes.scatterplot(x, y, size=10)

for frame in canvas.frames(len(x) + 1):
    if frame.number == 0:
        for i in range(len(x)):
            frame.set_datum_style(mark, 0, i, style={"opacity":0.1})
    else:
        frame.set_datum_style(mark, 0, frame.number - 1, style={"opacity":1.0})

#保存為mp4
#toyplot.mp4.render(canvas, "/home/xgj/Desktop/toyplot/test.mp4", progress=progress)
