Is it possible to change granularity on graphics? I have such schedule:
How can I change granularity? That data would be displayed not on days but on months. For example: Sep, Oct, Dec etc.

Answer 1

Change your query to group and count data on month
Example (mysql syntax)
SELECT DATE_FORMAT(SHIPPEDDATE,'%y %M') as LABEL, COUNT(ORDERID) AS CNT_ORDERID
FROM Orders
GROUP BY YEAR(SHIPPEDDATE), MONTH(SHIPPEDDATE)
ORDER BY SHIPPEDDATE
Note: this will change your fields in Dataset1 (just 2, LABEL and CNT_ORDERID) and bucketExpression, valueExpression will point to the new fields.
