Make a beautiful water polo chart in a few lines in Python

If you are tired of the charts you’ve seen a lot, you might be interested in placing a water polo chart in your report. The chart looks like this:

It is a dynamic chart and the water is flowing in the chart. It is very eye-catching.

To create this chart, you just need a few lines of Python codes.

Before you write these few lines of codes, you need to install the visualization package called Pyechart. It is a Python echarts plotting library. It provides more than 30 kinds of charts. The latest version is 1.7.1 and it was released on March 12th 2020. You can pip install it.

pip install pyecharts==1.7.1

After the library is installed, we can start to build the beautiful chart:

#import libraries

from pyecharts import options as opts
from pyecharts.charts import Liquid
from pyecharts.globals import SymbolType

Code to generate the water polo chart:

c = (
    Liquid()
    .add("Completion", [0.6])
    .set_global_opts(title_opts=opts.TitleOpts(title="% of sales target achieved",pos_left="center"))
)
c.render_notebook()

You can generate the file in html format as well.

c = (
 Liquid()
 .add(“Completion”, [0.6])
 .set_global_opts(title_opts=opts.TitleOpts(title=”% of sales target achieved”,pos_left=”center”))
 #Render the water polo map as html by the render() method
 . render(“round water polo. html”)
)

You can further beautify your chart by changing some parameters.

Remove the outline of the chart

Turn the is_outline_show into False, you will remove the outline of the chart.

c = (
 Liquid()
 .add(“Completion”, [0.6], is_outline_show=False)
 .set_global_opts(title_opts=opts.TitleOpts(title=”% of sales target achieved”,pos_left=”center”))
)
c.render_notebook()

Customize the color of the water polo

add the color parameter and put the hex color code.

c = (
 Liquid()
 .add(“Completion”, [0.6], is_outline_show=False,color=[‘#7733FF’])
 .set_global_opts(title_opts=opts.TitleOpts(title=”% of sales target achieved”,pos_left=”center”))
)
c.render_notebook()

Customize the shape of the water polo chart — round rectangular

The library provides many shapes for the water polo chart. For example, Rectangular, arrow, diamond, triangle, etc. I am going to draw a round rectangular chart.

c = (
    Liquid()
    .add("Completion", [0.6], is_outline_show=False, color=['#7733FF'],shape = SymbolType.ROUND_RECT)
    .set_global_opts(title_opts=opts.TitleOpts(title="% of sales target achieved",pos_left="center"))
    )
c.render_notebook()

Customize the shape of the water polo chart — diamond

c = (
    Liquid()
    .add("Completion", [0.6], is_outline_show=False, color=['#7733FF'],shape = 'diamond')
    .set_global_opts(title_opts=opts.TitleOpts(title="% of sales target achieved",pos_left="center"))
    )
c.render_notebook()

Customize the shape of the water polo chart — using SVG path method

#custom a SVG path looks like a whale
shape = ("path://M367.855,428.202c-3.674-1.385-7.452-1.966-11.146-1"

)
c.render_notebook()

With just few lines of Python codes, you can get this beautiful water polo chart. You can customize the shape and color to make the chart even more amazing.
