How to draw lines in matlab

Suppose x axis values are (30,40,50) and its corresponding y-axis values are (100,200,300). How to draw three different line in a plot with (30,100) one line,(40,200) one line and (50,300) one line. Thank you.

   X = [30,40,50] ;
   Y = [100,200,300] ;
   plot(X,Y,'.-r')

The plot should be like vertical lines..I have attached a sample

Vertical lines? YOu need to have data to plot what you have shown in figure.

[Aditya Shau]

Sorry, it is horizontally. Suppose x - axis the min and max values are 10 to 50 at an interval of 10, i.e. 10:10:50. similarly, in y-axis 100:100:500(interval of 100).

Now, how do we plot for the given data.

[KSSV]

x = 10:10:50. ;
y = 100:100:500 ; 

[X,Y] = meshgrid(x,y) ;

plot(Y,X,'k')

let me make my question clear..in x-axis I have some values and y-axis some values. I want to draw a continuous line from a point of the x-axis to y-axis. so,suppose we have to draw the contiious line from x-axis value (let 30) to yaxis value (let 100).. like in the attachment.i need to only connect the points through continious line.

X = [30,0];

Y = [0,100];

plot(X,Y,'.-r') A red line
