Selecting the Curves to be Plotted

Selecting the curves to be plotted


By default all curves are plotted, but you can select and deselect individual curves by clicking on their label buttons (under Key: ). If there are too many curves to fit into the vertical space availble a scroll-bar is added as shown to the right.


Only those curves selected for plotting are drawn when the next PLOT command is issued. You can use SEL_ALL and UNSEL_ALL to (de)select all of them, and the FILTER options to select and deselect curves by colour and/or label: see below.


The colours (white, red , green , blue, cyan , magenta , yellow ) and letters (A-Z) of curves are fixed and cannot currently be changed. The letters are used as "symbols" when symbol display is sturned on, as shown in the plot above.

Obtaining information about curves

You can use the popup menus against any "live" curve in the scrolling key to obtain the max/min X and Y axis data for that curve.

Here curve K has been selected.
