Combined Chart with GBARLINE

The script uses `goptions` to initialize graphics parameters. It opens an ODS HTML destination to save the graphical output to a `test.html` file. `PROC GBARLINE` is then used to create a chart overlaying bars (`product` by `sumvar=actual`) and a line (`sumvar=predict`). Finally, the ODS HTML destination is closed, completing the creation of the output file.

Data Analysis

Type : SASHELP

The data comes from the SASHELP library, specifically from the `PRDSALE` table, which contains product sales information.

1 Code Block

OPTIONS / ODS

Explanation :
This block initializes the graphics options by resetting all parameters and specifying the ActiveX graphics device. It then configures the ODS HTML destination to save the graphical output to the `c:\workshop\hw06\test.html` file.

2 Code Block

PROC GBARLINE

Explanation :
This block uses `PROC GBARLINE` to create a combined chart. It takes data from the `sashelp.prdsale` table. The `bar product / sumvar=actual` clause generates a bar chart where each bar represents a `product` and its height is the sum of the `actual` variable. The `plot / sumvar=predict` clause overlays a line on the same chart, representing the sum of the `predict` variable.

1	PROC GBARLINE DATA=sashelp.prdsale;
2	bar product / sumvar=actual ;
3	plot / sumvar=predict ;
4	RUN; QUIT;

3 Code Block

ODS

Explanation :
This block closes the previously opened ODS HTML destination, which finalizes the writing of the HTML file containing the chart.
