SGplot Horizontal Grouped Bar Chart (3D)

The main objective of this script is to visualize categorical data using a grouped bar chart. It first prepares a 'my_data' dataset using a DATALINES statement. Then, it configures the ODS destination system to generate HTML output, including an SGPLOT graphic in PNG format. The chart displays the sum of an 'AMOUNT' variable grouped by 'SERIES' and categorized by 'CATEGORY'. Style options are applied for better visual presentation, including a 3D shading on the bars ('dataskin=sheen'). Chart titles and axis attributes are also customized.

Data Analysis

Type : CREATION_INTERNE

The 'my_data' dataset is created internally within the script via a DATA step and the DATALINES statement. It contains three variables: 'CATEGORY', 'SERIES', and 'AMOUNT'.

DATA STEP Data

Explanation :
This block creates the 'my_data' dataset that will be used for the chart. Data is integrated directly into the script using the DATALINES statement, simulating data from various sources.

1	DATA my_data;
2	INPUT CATEGORY SERIES $ 3-11 AMOUNT;
3	DATALINES;
4	1 Series A 5
5	2 Series A 7.8
6	1 Series B 9.5
7	2 Series B 5.9

ODS Configuration

Explanation :
This block initializes the ODS (Output Delivery System) environment. It defines a macro variable 'name' to name the output files, closes the default ODS LISTING destination, and opens an ODS HTML destination to generate an HTML file. ODS GRAPHICS options are configured to produce a PNG image of the chart with specific dimensions, and titles are defined for the chart.

PROC SGPLOT

Explanation :
This procedure generates the horizontal grouped bar chart. It uses the 'my_data' dataset. The HBAR statement creates the bars, summing 'AMOUNT' and grouping them by 'SERIES' within each 'CATEGORY'. The 'dataskin=sheen' option applies a 3D effect to the bars. Style and axis attributes are customized to improve readability and aesthetics of the chart.

ODS Cleanup

Explanation :
This block properly closes the open ODS destinations, particularly the ODS HTML destination, and reactivates the ODS LISTING destination. The 'quit' statement terminates any currently running SAS procedure.
