Data Visualization with a focus on SAS ODS GraphicsThe LOESS statement in PROC SGPLOT finds a fit function while making no assumptions about the parametric form of the regression function.

This article is motivated by a recent question on the SAS Communities board. This user wants to create a series or spline plot where the attributes of the line (color, thickness) can be changed based on another variable. In this case it may be a binary variable with "0" and

You can use penalized B-splines display a smooth curve through a set of data. The PBSPLINE statement fits spline models, displays the fit function(s), and optionally displays the data values.

A common request on the communities page is to place data labels on horizontal bar charts. Often users want to display stacked horizontal bar charts, with the values displayed for each segment and the overall value of the bar itself as shown in the example below. In this example, the

An earlier SGMAP blog used the BUBBLE statement to overlay point data on top of an Open Street Map. However, not all map features are points. Some are enclosed areas called polygons. Some map polygons share common borders such as states and counties. Others are separate, non-contiguous regions such as national parks

The REG statement fits linear regression models, displays the fit functions, and optionally displays the data values. You can fit a line or a polynomial curve. You can fit a single function or when you have a group variable, fit multiple functions.
