Steps to create a funnel chart using ECharts and Python interface

The steps to create a funnel chart using ECharts and Python interface require specific code examples

The funnel chart is a visual chart commonly used to display data processes and conversion rates. In data analysis and business decision-making, funnel charts can clearly display conversion rates at different stages, helping analysts better understand data processes and optimize business processes. This article will introduce how to create a funnel chart using ECharts and Python interfaces, and provide specific code examples.

First, we need to install the necessary Python libraries and ECharts. In Python, we can use the ECharts-Python library to interact with ECharts. To install the ECharts-Python library, you can use the pip command:

pip install echarts-python

After the installation is complete, we can create a Python script to write specific code. Here are the steps to create a funnel chart:

1. Import the necessary libraries

from echarts import Echart, Legend, Pie,Axis

2. Define the data

data = [
    {"value": 100, "name": "进入网站"},
    {"value": 80, "name": "注册用户"},
    {"value": 60, "name": "完成购物"},
    {"value": 40, "name": "成功支付"}
]

3. Create ECharts object

chart = Echart("漏斗图示例", "数据转化率")

4. Add data

chart.use(Pie(r"转化率", data, radius=["10%", "80%"], center=["50%", "50%"], label={"normal": {"show": True, "position": "inner"}}))
chart.use(Legend(["进入网站", "注册用户", "完成购物", "成功支付"], "vertical", "left"))
chart.use(Axis('none', 'none',show=False))

5. Generate HTML file

chart.plot()

At this point, we have completed the creation Funnel chart code. Now we can execute the Python script and open the generated HTML file in a browser to view the funnel chart.

The complete code is as follows:

from echarts import Echart, Legend, Pie, Axis

data = [
    {"value": 100, "name": "进入网站"},
    {"value": 80, "name": "注册用户"},
    {"value": 60, "name": "完成购物"},
    {"value": 40, "name": "成功支付"}
]

chart = Echart("漏斗图示例", "数据转化率")
chart.use(Pie(r"转化率", data, radius=["10%", "80%"], center=["50%", "50%"], label={"normal": {"show": True, "position": "inner"}}))
chart.use(Legend(["进入网站", "注册用户", "完成购物", "成功支付"], "vertical", "left"))
chart.use(Axis('none', 'none',show=False))
chart.plot()

After executing the above code, a file named "Funnel Chart Example.html" will be generated in the current directory, which can be opened through a browser to view the file. Funnel chart. In the browser, you will see a funnel chart with different conversion rates to help you better understand the data conversion process.

Summary: This article introduces how to create a funnel chart using ECharts and Python interfaces, and provides specific code examples. Through the ECharts-Python library, we can create a funnel chart with a few simple lines of code and view the generated visual chart in the browser. Using funnel charts, we can understand the data flow and conversion rate more intuitively, allowing us to make more accurate data analysis and business decisions.
