MATLAB: Plots the axis scale

axiisplots

I have two plots with the same x-axis but their y-axis are scaled differently. how do I make them the same scale?
Here is my plots command
zero_vector = zeros(size(Standard_error_positive_INFLP));  % just the straight line 
%    zero_vector = zeros(1,min(size(Z_pbw,1),size(W,1)));
  figure(1)
  plot(Confidence_interval_Negative_INFLPS(1,:), '-b')
  title('Negative Inflection Points Confidence Interval')
  hold on
  plot(Confidence_interval_Negative_INFLPS(2,:), '-b')
 %plot(, 'rp')
  plot(zero_vector)  % plot straight line at zero
  hold off
    figure(2)
    plot(Confidence_interval_Positive_INFLPS(1,:), '-b')
    title('Positive Inflection Points Confidence Interval')
    hold on
    plot(Confidence_interval_Positive_INFLPS(2,:), '-b')
 %  plot(, 'rp')
    plot(zero_vector)  % plot straight line at zero 
    hold off

You may have to use two y-axes, with the new yyaxis or older plotyy functions.
Also see the documentation on Axes Properties (link) if you need to adjust either one to create the scaling you want.
