Horizontal Stacked Bar Chart

The script begins by defining a macro variable `name`. It then creates a dataset named `my_data` using a DATA step with `datalines` to include the data directly within the script. This data contains information on categories, series, and amounts. The script then uses ODS (Output Delivery System) to generate HTML output containing an SGPLOT graph. The graph is a horizontal stacked bar chart that compares amounts by `CATEGORY`, grouped by `SERIES`. Style attributes and titles are applied to the chart. The image is exported in PNG format within the HTML file.

Data Analysis

Type : INTERNAL_CREATION

Data is created directly within the script via a DATA step and the DATALINES statement.

1 Code Block

Macro/Global

Explanation :
Defines a macro variable `name` used for the output filename and assigns the `odsout` fileref to the current directory.

Copied!

1	%let name=bar3;
2	filename odsout '.';

2 Code Block

DATA STEP Data

Explanation :
Creates the `my_data` dataset by reading embedded raw data (datalines) with CATEGORY, SERIES, and AMOUNT variables.

Copied!

1	DATA my_data;
2	INPUT CATEGORY SERIES $ 3-11 AMOUNT;
3	DATALINES;
4	1 Series A 5
5	2 Series A 6.8
6	3 Series A 9.2
7	1 Series B 6.5
8	2 Series B 6.9
9	3 Series B 5.6
10	;
11	RUN;

3 Code Block

ODS

Explanation :
Closes the default LISTING output and opens an ODS HTML environment to generate the report. Specifies the output path, HTML filename, and style.

Copied!

1	ODS LISTING CLOSE;
2	ODS HTML path=odsout body="&name..htm"
3	(title="SGplot Horizontal Stacked Bar")
4	style=htmlblue;

4 Code Block

ODS GRAPHICS

Explanation :
Configures graphic options for ODS, defining the image format (PNG), image name, size, and other attributes.

Copied!

1	ods graphics / imagefmt=png imagename="&name"
2	width=800px height=600px noborder imagemap;

5 Code Block

Global Statements

Explanation :
Defines the main and secondary chart titles with specific color, size, and font options.

Copied!

1	title1 color=gray33 ls=0.5 h=23pt "Horizontal Stacked Bar";
2	title2 color=gray33 ls=0.5 h=17pt "Compares the contribution of each value";
3	title3 color=gray33 ls=0.5 h=17pt "to a total across categories";

6 Code Block

PROC SGPLOT

Explanation :
Executes the SGPLOT procedure to create a horizontal stacked bar chart. Uses `my_data`, specifies bar colors, X-axis (response and statistic), and Y-axis (category) with formatting and style options.

Copied!

1	PROC SGPLOT DATA=my_data noautolegend;
2	styleattrs datacolors=(cx9999ff cx993366);
3	hbar category / response=amount stat=sum
4	group=series /groupdisplay=cluster grouporder=descending/
5	outlineattrs=(color=black) nostatlabel;
6	xaxis
7	values=(0 to 16 BY 4)
8	labelattrs=(size=16pt weight=bold color=gray33)
9	valueattrs=(size=16pt weight=bold color=gray33)
10	offsetmax=0 grid minor minorcount=1;
11	yaxis
12	labelattrs=(size=16pt weight=bold color=gray33)
13	valueattrs=(size=16pt weight=bold color=gray33)
14	display=(noticks);
15	RUN;

7 Code Block

ODS

Explanation :
Ends the SGPLOT procedure (`quit`), closes the ODS HTML file, and reactivates the default LISTING output.

Copied!

1	QUIT;
2	ODS HTML CLOSE;
3	ODS LISTING;
