Scenario

In this scenario, we will create a xyLine chart to display "Books Printed vs. Sold" for the first 24 months in circulation. 

Background

Our scenario will use a Data Source Profile called "BookWarehouse" to query a rollup database table called "CIRCULATION". The table contains aggregate metadata associated with the circulation of books which are rolled-up and reported on by year. For this scenario, we will focus on charting print vs. sold totals for the book "Nineteen Eighty-Four" in it's first year of circulation (1949):

SQL > SELECT * FROM circulation WHERE book_id =24 and year=1949;
+---------+---------+----------+-----------+-----------+-----------+
|type    | 6_months | 12_months | 18_months | 24_months | year |
+---------+---------+----------+-----------+-----------+-----------+
|Printed |  8500.00 |  12000.00 |  20000.00 |  25000.00 | 1949 |
|Sold    |  9340.00 |  19000.00 |  14000.00 |  27000.00 | 1949 |
+---------+---------+----------+-----------+-----------+-----------+

Our example query against the CIRCULATION table looks like:

SELECT type as "Statistic Type"
,format(6_months,0) as "6"
,format(12_months,0) as "12"
,format(18_months,0) as "18"
,format(24_months,0) as "24" 
FROM circulation where year='1949' 
 AND type='Printed'
UNION
SELECT type as "Statistic Type"
,format(6_months,0) as "6"
,format(12_months,0) as "12"
,format(18_months,0) as "18"
,format(24_months,0) as "24" 
FROM circulation where year='1949' 
 AND type='Sold';

Steps

The following steps will demonstrate how to use Markup to insert Confluence's native Chart Macro and our SQL Macro on a Confluence page.

Create Confluence page

Create a Confluence page that will eventually contain the macros needed to produce the chart.

1. Create a page named Books in Circulation in a space accessible to the desired audience.
2. Click Save to close the Page Restrictions screen.
3. Click Save to save to publish the new page.

Configure the Chart macro

Edit the Books in Circulation page and do the following:

1. Insert the Chart macro.
2. Click the Chart macro container and click Edit so you can adjust its parameters as shown on the right.
   • The Type parameter indicates to display a xyLine chart.
   • The Width parameter indicates the width of the chart in pixels.
   • The Height parameter indicates the height of the chart in pixels.
   • The Chart Title parameter provides a title for the chart.
   • The Chart Subtitle parameter provides a subtitle for the chart.
   • The Show legend parameter will display the name associated with the colored bars rendered.
3. Click Save to save your changes to the Chart macro's parameters.

Chart macro parameters:

Type	pie
Width (pixel value only)	600
Height (pixel value only)	400
Chart Title	Nineteen Eighty-Four
Chart Subtitle	Books Printed vs. Sold in 1949
Show legend

Configure the SQL Query macro

This step uses the SQL Macro, to retrieve the data that will be displayed in the bar chart. To configure the SQL  Macro, do the following:

...

• The Data source name parameter indicates to use the BooksWarehouse data source profile that you set up.
• The Use database column labels parameter indicates to use the column names defined within the SELECT statement (e.g., Publisher, M Rev.) rather than the columns names defined within the database table(s) themselves.
• The Show error if there are no rows parameter indicates to show an error if no rows are returned in the resultset of the SQL query.
• The Text to display when there are no rows parameter indicates the text of the error message to be displayed when no rows are returned in the resultset of the SQL query.

...

With the cursor positioned inside the SQL Macro container, paste in this SQL statement:

SELECT type as "Statistic Type"
,format(6_months,0) as "6"
,format(12_months,0) as "12"
,format(18_months,0) as "18"
,format(24_months,0) as "24" 
FROM circulation where year='1949' 
 AND type='Printed'
UNION
SELECT type as "Statistic Type"
,format(6_months,0) as "6"
,format(12_months,0) as "12"
,format(18_months,0) as "18"
,format(24_months,0) as "24" 
FROM circulation where year='1949' 
 AND type='Sold';

Using your mouse, "drag" the SQL Macro container into your Chart Macro container (see right).
