basically we always plot graph of certain function such as x = 0 : 1 : 10 y = sinx; plot(x,y,'-r^')

lets say given x = 2 y = 15 x = 3 y = 8 x = 8 y = 30 the point is random, how to plot this graph?

x=[2,3,8]; y=[15,8,30]; plot(x.y)

plot(x,y,'o') for dots

From the Graph window, you can go to File -> Save as

or click on Save Figure

and then select JPEG image (*jpg) as a type

... and save it as a PNG, not a JPG. Never save plots as a JPG.
