Hello. I am needing to plot a three line graph with two y-axis. One line will be tied to the left y-axis, and two lines will be tied to the right y-axis. The two lines plotted against the right y-axis need to be black (one solid the other dashed). The tick range and the limits on the left y-axis will be (MatLab) auto generated based on the values being plotted. The tick range on the right y-axis will be 0.0 to 1.0 with a tick at every 0.1 unit, and it's limits -0.1 to 1.1. The problem stems from plotyy adding left y-axis tick marks to the right y-axis, which I not what I want. So how can I remove left y-axis tick marks from the right y-axis, AND retain the top x-axis? Below is a segment from my script attempting to plot what I just described.
I have been unsuccessful finding a solution in MatLab Central that will work on 2015a.
Regards, Ed
[ax,~,H2] = plotyy(x,y1,x,[y2, y3],'plot'); % plot the graph (y1 = left y-axis, y2 & y3 = right y-axis)
set(H2(1),'LineStyle','-','Color','black'); % set y2 plot to be a solid black line
set(H2(2),'LineStyle','--','Color','black'); % set y3 plot to be a dash black line
set(ax(2),'YLim',[(-0.1) 1.1]); % set plotting limits for right y-axis
set(ax(2),'YTick',0.0:0.1:1.0); % set the tick properties for right y-axis
set(ax,'YColor','black); % make both y-axis black
set(ax(1),'Box','Off'); % remove left y-axis tick marks from the right y-axis ... BUT THIS ALSO REMOVES THE TOP X-AXIS, WHICH IS NOT WHAT I WANT TO DO
% the following are commands I tried without success. Note: I tried these commands separately per execution.
set(ax,'XAxisLocation','top','XTicklabel',[]); % one attempt
set(ax(1),'XAxisLocation','top','XTicklabel',[]); % another attempt
set(ax(2),'XTicklabel','','XAxisLocation','top'); % another attempt
