how to plot os many curves in one figure with distinct marker?

I want to draw many plots (say 30) in one figure with distinct color and maker. How can I ask MATLAB to do it automatically?

If I use a loop, it gives all the plots the same color and type.

So I have to use something like this which is too long:

plot(x1,y1,x2,y2,.....x30,y30)

Is there a better way?

Also how can I set the legend for them? Again I have to use such long command for legend:

legend("Plot1','Plot2',....)

Any better way?

Thanks!

You may wish to have a look at the FEX contribution "plt".

Otherwise have a more detailed look at "hold all" and the axes properties ColorOrder and LineStyleOrder.

Remember that you can feed legend() a cell array of strings. Alternately you can feed legend the handle for a graphics object and the legend string to associate with it. See also http://www.mathworks.com/help/matlab/creating_plots/controlling-legends.html

Thanks!

But the "plot" plots all the curves by default as lines.

How can I ask it to draw the plots as distinct markers automatically?

set the axis LineStyleOrder to only consist of markers. http://www.mathworks.com/help/matlab/ref/axes_props.html

An example given in that documentation is

set(gca,'LineStyleOrder',{'-*',':','o'})

The third of those LineStyleOrder entries is 'o' which is marker only. You can use any of the markers shown at http://www.mathworks.com/help/matlab/ref/linespec.html
