3D Bubble Plot Generation

The script initializes a macro variable to name the HTML output file and assigns the current directory to the 'odsout' fileref. It then creates a dataset named 'my_data' using inline data (datalines). The ODS (Output Delivery System) is configured to generate HTML output and a PNG image of the plot, with custom titles. The SGPLOT procedure is used to create the bubble plot, with style options, grouping by series, and detailed customization of the X and Y axes.

Data Analysis

Type : CREATION_INTERNE

The 'my_data' dataset is created directly in the SAS script via a DATA STEP and DATALINES instructions, providing the variables 'series', 'x', 'y', and 'value'.

MACRO VARIABLE / FILENAME

Explanation :
Defines the macro variable `name` to name the HTML output file and assigns the current directory to the `odsout` fileref for output file management.

4	Set your current-working-directory (to read/write files), if you need to ...
5	%let rc=%sysfunc(dlgcdir('c:\someplace\public_html'));

7	filename odsout '.';

DATA STEP Data

Explanation :
Creates the 'my_data' dataset in memory using a DATA STEP. It defines the variables 'series', 'x', 'y', and 'value' from the data provided directly via `datalines` instructions.

1	DATA my_data;
2	LENGTH color $ 8;

ODS / TITLE

Explanation :
This block manages the Output Delivery System (ODS) configuration. It closes the default LISTING output and opens an ODS HTML destination to write the plot to an HTML file. ODS Graphics options are configured to generate a PNG image of the plot with specified dimensions. Custom titles are defined for the plot with specific colors and font sizes.

4 Code Block

PROC SGPLOT

Explanation :
Executes the SGPLOT procedure to create a 3D bubble plot. The 'my_data' dataset is used. Bubble colors are defined, and bubbles are grouped by the 'series' variable. X and Y axes are fully customized with value ranges, labels, text attributes, and grids. Bubble size is proportional to the 'value' variable.

ODS CLOSURE

Explanation :
Closes the ODS HTML destination, thereby stopping writing to the HTML file, and reactivates the default ODS LISTING destination.
