Scenario

In this scenario, we will create a 3-D bar chart to display "Top Publishers by Revenue (in $M). 

Background

Our scenario uses a data source profile called "BookWarehouse" to query a database table called "PUBLISHERS". The table contains the following columns and rows:

SQL > select * from publishers;
+----+------+-------------------+-----------------+---------+
| id | rank | parent_company    | company_name    | revenue |
+----+------+-------------------+-----------------+---------+
| 10 | 1    | Pearson           | Pearson         | 5000.00 |
| 11 | 2    | Reed              | RELXGroup       | 4900.00 |
| 12 | 3    | WoodbridgeCompany | ThompsonReuters | 4700.00 |
| 13 | 4    | BertelsmannAG-NV  | Bertelsmann     | 4500.00 |
| 14 | 5    | WoltersKluwer     | WoltersKluwer   | 4100.00 |
+----+------+-------------------+-----------------+---------+

Our example query against the PUBLISHERS table looks like:

SELECT company_name as "Publisher", CONCAT('$',format(revenue,0)) as "M Rev" FROM publishers ORDER BY rank asc;

Steps

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

Configure the Chart macro

Edit the Top Publishers Worldwide 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 following parameters indicate:
   • Type - type of a chart.
   • Width - width of the chart in pixels.
   • Height - height of the chart in pixels.
   • Display rendered data - a data table should be displayed after (below) the chart.
   • Chart Title - title for the chart.
   • Show in 3-D - add dimension to the bars within the chart.
   • Opacity - recommended when using 3-D and for bar the recommendation is 75%.
   • Horizontal-axis - column values rendered on the horizon line.
   • Vertical-axis - column values rendered on the vertical line.
   • Show legend - 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	Top Publishers by Revenue
Show in 3-D
Opacity	75
Horizontal-axis label	Publisher
Vertical-axis label	Revenue (in $M)
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:

...

• Data source profile - name of the data source profile that you set up.
• Use database column labels - usage of 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.
• Show error if there are no rows - displays an error if no rows are returned in the resultset of the SQL query.
• Text to display when there are no rows - text of the error message to be displayed when no rows are returned in the resultset of the SQL query.

...

Paste the SQL statement in SQL settings > SQL statement > SQL statement:

SELECT company_name as "Publisher"
,CONCAT('$',format(revenue,0)) as "M Rev" 
FROM publishers 
ORDER BY rank asc;

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