You can get the corresponding points and use plot to draw a line.

To show up the text, you can use the function text.

hello ,

but i only know the y values.

i need to draw a line to it and find x value

[KSSV]

Use the inequality and get the index of y to find x.

[Sajid Afaque]

but since i am using directly

cdfplot(z) ; 

to plot the graph i do not get values of y or the index.

please elaborate and explain if i am wrong

[KSSV]

h = cdfplot(z); 

h should have data points.

i have plotted the lines.

Now i need to indicate the corresponding values of x at position 1 and 2.

since the xvalue at position 1 and 2 changes each time , if i use text i cannot have the textbox fixed at particular location.

so how can i dynamically introduce something that correctly represents x values at corresponding places
