Returns
boolean

Description
This gplot1d-emulator plots a collection of Y vectors with auto-scaling against a single X vector. If there is more than one Y vector, they should be arranged in a 2-D array with the first dimension being the number of vectors to plot and the second dimension being the length of each vector. The length of the X axis vector must be the same as the length of each Y vector. The color of each Y vector on the plot will be different for the first 16 plots, after that the colors will cycle through the same 16 colors. The ylabflag determimes whether the y axis label is printed on the plot itself, in addition to the y axis. For a single plot, this may sensibly be set to false. However, if plotxy1 is called repeatedly without clearing the plot, the successive calls will overplot the new data on the original, and having this flag set to true is useful for determining which color plot corresponds to which data. This function is called plotxy1 to distinguish it from the standard pgplotter function, plotxy, which has some subtle differences.

Example

include 'pgplotter.g'
pg := pgplotter();
x := 1:100;
y1a := sin(x/10);
y1b := cos(x/10);
y2 := sqrt(x);
pg.plotxy1(x,y1a,'X Index','Sine Function','Title');
pg.plotxy1(x,y1b,,'Cosine Function');
pg.plotxy2(x,y2,,'SQRT Function');
pg.ptxt(105,5.5,270,0.5,'SQRT (X)');
