Details:

When 2 axes with right y-axes and at least one boxed axes-object with left
yaxis are used, the second y axis somehow takes over the ticklabels of the
first right y-axis for the (not to be tick-labeled) left tickmarks of the
boxed axes-object with left-yaxis.

I know this sounds confusing, which is probably the reason why this has not
been spotted before, here is an example:


pos1=[.15,.15,.75,.4];
pos2=[.15,.55,.75,.4];
boxstate="on";

#this results in wrong output
figure(1)
clf
ax2=axes("nextplot","add")
plot(1:10,sqrt(3.6:12.6),"r")
set(ax2,"yaxislocation","right","yticklabel","2","position",pos1,"box",boxstate,"color","none")
ax3=axes("nextplot","add")
plot(1:10,sqrt(2.1:11.1),"c")
set(ax3,"yaxislocation","left","yticklabel","3","position",pos2,"box",boxstate,"color","none")
ax4=axes("nextplot","add")
plot(1:10,sqrt(3.1:12.1),"k")
set(ax4,"yaxislocation","right","yticklabel","4","position",pos2,"box",boxstate,"color","none")

#without the boxed, left yaxis, axes-object it works
figure(2)
clf
ax2=axes("nextplot","add")
plot(1:10,sqrt(3.6:12.6),"r")
set(ax2,"yaxislocation","right","yticklabel","2","position",pos1,"box",boxstate,"color","none")

#ax3=axes("nextplot","add")
#plot(1:10,sqrt(2.1:11.1),"c")
#set(ax3,"yaxislocation","left","yticklabel","3","position",pos2,"box",boxstate,"color","none")

ax4=axes("nextplot","add")
plot(1:10,sqrt(3.1:12.1),"k")
set(ax4,"yaxislocation","right","yticklabel","4","position",pos2,"box",boxstate,"color","none")

#without boxing it works as well
boxstate="off";

figure(3)
clf

ax2c=axes("nextplot","add")
plot(1:10,sqrt(3.6:12.6),"r")
set(ax2c,"yaxislocation","right","yticklabel","2","position",pos1,"box",boxstate,"color","none")

ax3=axes("nextplot","add")
plot(1:10,sqrt(2.1:11.1),"c")
set(ax3,"yaxislocation","left","yticklabel","3","position",pos2,"box",boxstate,"color","none")

ax4c=axes("nextplot","add")
plot(1:10,sqrt(3.1:12.1),"k")
set(ax4c,"yaxislocation","right","yticklabel","4","position",pos2,"box",boxstate,"color","none")
