Pie grid

As the name suggests, a pie grid is a grid of small single-value pie charts. Here is a simple example:

Parameters

In addition to all of the standard parameters the following apply to pie charts.

dataList[dict], DataFrame, Series

Contains inline data to use for the chart. In Markdown, the value must be a JSON string representing a list of dictionaries, as shown in the example below. Each dictionary must contain a label element, with the label for the respective slice, and a value element, representing the extent of the slice (which will be scaled appropriately).

In Python, data may be any of:

• A Python list of dictionaries, as above
• A Pandas, FireDucks, Polars or pyarrow DataFrame with a label and value column.
• A Series whose index supplies the labels and entries supply the value.

labelstring

valuestring

If you would like to use different columns instead of the standard "label" and "value" columns, you may specify one or both using the label and/or value parameters like this:

<piegrid
data='[
  { "category": "Apples", "value": 10 },
  { "category": "Bananas", "value": 20 },
  { "category": "Cherries", "value": 15 },
  { "category": "Grapes", "value": 25 }
]'
  width=500
  height=150
  colors='deep'
  label='category'
>
</piegrid>

columnsinteger

Specifies the number of pie charts per row. The default is 3.

show_percentagesBoolean

If true, the percentage that the value is of the sum of the values is added to the chart.

bg_arc_colorstring

text_colorstring

percent_colorstring

total_colorstring

The colors of the chart elements may be specified using these four optional parameters. The meanings of each parameter are as follows:

Param	Default	Component
bg_arc_color	#2b2b2f	The portion of the circle not representing the value
text_color	#aaa	The color of the label text
percent_color	#eb0707	If show_percent is true, the color of its text
total_color	#aaa	The color of the value text
