plotting

I am trying to make a plot of a 2-dimensional vector (2D Plot). But I don't want all the datapoints to have the same color on the plot. Each datapoint corresponds to a group. I want to have different colors for each group of datapoints.

class=[1 3 2 5 2 5 1 3 3 4 2 2 2]

says each datapoint belongs to which group

X=[x1,y1;x2,y2;x3,y3;.....]

the number of these datapoints are the same as the number of elements in the class vector.

Now I want to plot these based on colors.

I have to plot many lines in GNU PLOT.No problem with the X axis. The problem that I am facing is that most of the plotted lines are at yscale [0-0.05] ,few at range 60-70 and rest at 600-700. These numbers correspond to the y axis scale values. But after I plot I can see only 3 sets of lines all… >>> More
