How can I change the length of a line using the xline() function?

Recently, I was trying to make a graph wihich required a vertical line to be of a specific length (so it stops at a line plot, and not cut through). Coudn't find any functions. How can I do that?
xline([1336.5 648],"r--")
(The part that I want to remove)

Hi @Md Affan
Since you know the coordinates, you can directly use the plot() function.
% plot([x1, x2], [y1, y2]) creates a line between (x1, y1) and (x2, y2)
plot([1336.5 1336.5], [350 648], 'r--'), ylim([350 700]), grid on

@Md Affan, Maybe you forgot to divide by 255.
myColor = [126, 47, 142]; % color for violet
plot([1336.5 1336.5], [350 648], '--', 'color', myColor/255)
ylim([350 700]), grid on

Dear Affan,
I can see that you are trying to introduce vertical lines in your graph with specific X and Y values.
There is not a direct line functionality that provides control over the vertical plot for your use case but one way of doing it is by using discrete data plots like "Stem Plots". You can find the functions associated with it in the following MathWorks documentation link, http://www.mathworks.com/help/matlab/stem-and-stair-plots.html.
Hope it helps.
