Trying to create a base line that the function starts at.

Hey I need a have my graph start at 80 y-value and act normally, and the base value of 80 needs to be a flat dashed line across. I have called a function and I am just trying to plot it where it starts at the base value of 80. I have attached a screenshot of my matlab code.

See the yline function to draw your flat dashed line.

What do you want to do if the data you've calculated starts at y = 50? Do you want to just add 30 to all the values?

What if it starts at y = 100? Do you want to subtract 20?

Or do you want to just add a value to that one point, or multiply by a scale factor that moves that first point to be at y = 80, or change the labels, or ... ?

So sorry for any confusion, I have attached my the graph i get when I run my code and what my graph should look like. Basically the dotted line on the correct graph is the basal glucose level of a healthy adult and after a meal the blue line is the spike in glucose and then the decrease for a healthy adult and the red line is the spike in glucose for a diabetic adult, I just need the baseline to ba at 80 mg/L so that after any meal the spike will always be above go above 80.
