This sample uses PROC GPLOT together with the Annotate facility to simulate a KAGI graph. In the graphics output, the variations in line thickness and line color have meaning. Typically used to follow stock prices, this example generates a thicker green line when the price rises and a narrower red line when the price falls.

This sample uses PROC GPLOT together with the Annotate facility to simulate a KAGI graph. In the graphics output, the variations in line thickness and line color have meaning. Typically used to follow stock prices, this example generates a thicker green line when the price rises and a narrower red line when the price falls.

The graphics output in the Results tab was produced using SAS® 9.2. Submitting the sample code with releases of SAS prior to SAS 9.2 might produce different results.
