- TRACENUM = expr; Enable/disable trace numbers
-
- TRACENUM enables and disables trace numbering on plots. When
- symbols are used to identify traces on a plot, the trace numbers
- are frequently superfluous and may add too much clutter to the
- plot. In such a case the trace numbers may be turned off.
-
- Trace numbers can be applied to one trace but not to another by
- grouping the PLOT and TRACENUM statements. For example,
-
- TRACENUM=OFF & PLOT(x*x) &
- TRACENUM=ON & PLOT(x*x*x + 2*x*x + 3);
-
- Even though a trace may have no trace number applied to it, the
- trace still reserves its own number, and consequently, there may be
- gaps in the trace numbers if at least one trace has had its
- numbering disabled. In the above example the trace that is
- numbered is given trace number 2.
