Master the 'vincent' class library in Python, and easily create unique data visualization
Overview:
Data visualization plays an important role in data analysis and data transmission.Python provides many powerful data visual libraries. Among them, the 'vincent' class library is a powerful and simple tool that can help you create unique data visualization.
Introduction 'vincent' class library:
'Vincent' is a Vega -based Python data visual library.It provides a method of creating drawing and visualization quickly and simply, and also supports seamless integration of data processing libraries such as Pandas.
Install the 'vincent' class library:
To use the 'Vincent' class library, we need to install it in your Python environment.You can use the following commands to use PIP for installation:
pip install vincent
Import library:
After installing the "Vincent 'class library, you can import it in the code:
python
import vincent
Create simple data visualization charts:
The following is a sample code for creating a simple chart using the 'vincent' class library:
python
# Create data
data = {
'x': [1, 2, 3, 4, 5],
'y': [2, 4, 6, 8, 10]
}
# Create a chart
bar = vincent.Bar(data, width=400, height=200)
# Display chart
bar.display()
The above code creates a simple strip map.First, we created a dictionary containing x and y values as data.Then, use the 'vincent.bar' classes to create a format object, pass the width and height of the data and set the chart.Finally, use the "Display () 'function to display the chart.
Advanced data visualization:
The 'Vincent' class library also provides other chart types and advanced configuration options to meet more complicated visual needs.The following is a sample code for drawing cake maps:
python
# Create data
data = {
'data': [20, 30, 50],
'age': ['18-30', '31-50', '51+']
}
# Create a chart
pie = vincent.Pie(data, inner_radius=0.4)
# Display chart
pie.display()
The above code creates a simple cake map, showing the data ratio of different ages.Similar to the previous examples, we created a dictionary containing data and corresponding tags, and then used the 'vincent.pie' class to create cake map objects.By setting the inner radius parameters 'inner_radius', we can achieve the effect of the ring cake diagram.
Summarize:
'Vincent' class library is a powerful data visualization tool that can help users easily create a variety of unique charts.This article briefly introduces the basic usage of 'Vincent' and provides a simple example code.By further exploring the documents and examples of the "Vincent 'class library, you can use its rich configuration options and chart types to create more complex and exquisite data visualization charts.
