Pie layered chart

Overview

The layered pie chart is a pie chart with concentric layers to show successive levels of data.

What data do I need for this widget?

The option to create this chart will be disabled unless your query contains at least one column with numeric values. Furthermore, to show meaningful content on the chart, you must group your data.

Creating a pie layered chart

1. Go to Data Search and open the required table.

2. Perform the required operations to get the data you want to use in the chart.

3. Click the gear icon on the toolbar and select Charts → Diagrams → Pie Layered Chart.

4. Click and drag the column headers to the corresponding fields. This diagram requires you to specify at least two fields:

   Required field	Data type
   Signals	Any type but json
   Value	float, integer, duration

   You can drag more than one column to the Signals field and each of them will be represented as a new outer layer.

5. The pie layered chart is displayed.
   
   

Working with pie layered charts

Hover over a segment on the chart to see the values of the assigned fields and the percentage of the total they represent.

Click on a segment to analyze it in detail, thus hiding all internal layers. A new version of the chart is generated consisting of the chosen segment and the corresponding outer-layer segments. Click the inner circle to show the full chart again.

Query example

You can recreate the example shown in the picture above with the data from the following query and mapping the fields as follows:

from demo.ecommerce.data
  group every 5m by statusCode, bytesTransferred
  every 5m

In case you want another example with more than one argument to add, here is another query to create it:

from demo.ecommerce.data
  group every 5m by method, statusCode, bytesTransferred
  every 5m
