CIAO allows some plot attributes to be changed using the ChIPS state object and resource file. See "ahelp chips" for further details.

Example 1

chips> CURVE data/exampleA.dat
chips> CURVE data/exampleB.dat
chips> C 1 SYMBOL UPTRI
chips> C 2 SYMBOL DIAMOND

First, two curves are plotted into a single drawing area. Curve 1 is changed to UPTRI and curve 2 is changed to DIAMOND.

Example 2

chips> C 1 SYMBOL CYAN
chips> C 2 SYMBOL RED

Curves 1 and 2 are changed to be cyan and red, respectively.

Example 3

chips> C 1,2 SYMBOL SIZE 2.0

The symbol size for both curves is increased to 2.0.

Example 4

chips> CLEAR
chips> CURVE data/exampleA.dat
chips> SYMBOL DIAMOND
chips> SYMBOL DOWNTRI
chips> SYMBOL SIZE 2.0
chips> SYMBOL DIAMOND

The first two SYMBOL commands illustrate the DIAMOND and DOWNTRI symbols at their default size of 3.0. The SYMBOL SIZE 2.0 command then changes the size of the current DOWNTRI symbols. The final SYMBOL DIAMOND command shows that changing the new style retains the last SYMBOL SIZE instruction.
