One last question about plotting cell array

So I get that I can have my data arranged like:

x1, y1, linespec1, x2, y2, linespec2, etc...

What about creating a legend? Can I add in the legend string after linespec?

No. The standard linespec strings are the only per-line properties you can set in a single plot() call. You will have to use the plot() form that returns the lineseries handles and set() the DisplayName property of each handle.

I'm a little confused on returning the lineseries handles (still getting the hang of handles).

I create a figure, plot:

f=plot()

I have a few series of data. How is the lineseries different from linespec?

How come I can use:

set(h(1),'LineColor','g') but not set(h(1),'DisplayName','Data')?

@Jared: I share your confusion. I ancient Matlab versions PLOT and LINE replied the same vector of line handles. But today there are differences:

plotH = plot(rand(5)); get(plotH(1));

lineH = line(1:5, rand(5)); get(lineH(1));

Unfortunately both handles claim that they have the Type 'line'. Is there a reliable method to dinstinguish them automatically?

[Walter Roberson]

One way would be that lineseries have four extra (visible) properties that line do not have: XDataMode XDataSource YDataSource

ZDataSource

Another way is that

class(handle(h)) is 'line' for line objects, but 'graph2d.lineseries' for lineseries objects.
