Pie Chart with MySQL datasource

Hi,

I want to create simple Pie Chart with MySQL datasource.

I use two simple querys: SELECT SUM(amount) as Monthly FROM tblhosting WHERE domainstatus = 'active' and billingcycle = 'Monthly'; SELECT SUM(amount)/12 as Annually FROM tblhosting WHERE domainstatus = 'active' and billingcycle = 'Annually';

When I try create Table with this querys it works fine. But when try the same with “Pie Chart” I got error: undefined is not an object (evaluating 'this.datapoints.length')

Query Inspector:

xhrStatus:“complete”
request:Object
method:“POST”
url:“api/tsdb/query”
data:Object
from:“1525941113670”
to:“1525962713671”
queries:Array[2]
response:Object
results:Object
A:Object
refId:“A”
meta:Object
rowCount:1
sql:“SELECT SUM(amount) as Monthly FROM tblhosting WHERE domainstatus = ‘active’ and billingcycle = ‘Monthly’;”
series:null
tables:Array[1]
B:Object
refId:“B”
meta:Object
rowCount:1
sql:“SELECT SUM(amount)/12 as Annually FROM tblhosting WHERE domainstatus = ‘active’ and billingcycle = ‘Annually’;”
series:null
tables:Array[1]
0:Object

@itayB will provide an example, but recommend you to have a look at Grafana’s community site which is more suitable for questions.

Using latest Grafana (5.3-pre1)

SELECT
  now() as time_sec,
  count(value),
  measurement
FROM 
  grafana_metric
GROUP BY 3

Generates the following without any other options specified:

The piechart panel only works with time series data which means that you’ll need to select a time_sec column in your query for the time - you should be able to use now() to return the same time for all your rows .
