When using yyaxis is there a way to plot the right yaxis data behind the left yaxis data?

I am trying to plot data on two different axes. I want the data associated with the right y axis (red lines) to plot behind the data points associated with the left y axis. Right now the right axis data is plotting in the front even though I run those lines first. Is there a way to fix this? I don't want to change the y axes (pH makes more sense on the right). Thank you for any advice!

This is how I am plotting now:

figure

yyaxis right

hold on

box on

plot(MX,PH2_1d,'-','color','r','linewidth',3)

plot(MX,poPH3_1d,':','color','r','linewidth',3)

ylim([7.85 8.35])

ylabel('pH')

yyaxis left

hold on

plot(MX,flo_ugL,'.','Color',[.6 .6 .6],'markersize',1)

errorbar(n_sdn,nflo_mean,nflo_std,'.','markersize',22,'color',[0 .4 .4],'capsize',0,'linewidth',1)

plot(date_nf_off,fronds2,'.','markersize',49,'Color','k')

ylabel('[Chlorophyll-a]')

ylim([0 30])

x = datenum('June-27-2018'):7:datenum('Oct-3-2018');

set(gca, 'XTick', x);

datetick('x','mm/dd','keepticks');

ax=gca; % make y axes black

ax.YAxis(1).Color='k'

ax.YAxis(2).Color='k'

set(gca,'fontsize',font)

Normally uistack would work, but see here:

You might alternatively consider plotting your data on two separate axes, with the top axes transparent ('Color' set to 'none'):

f = figure;

ax1 = axes(f, 'NextPlot', 'add', 'YAxisLocation', 'right', 'Box', 'on');
p1 = plot(ax1, 1:100, 10*rand(100,1),'-','color','r','linewidth',3) ; 
p2 = plot(ax1, 1:100, 10*rand(100,1),':','color','r','linewidth',3);
ylabel(ax1, 'more random numbers')
xlabel(ax1, 'index')
 
ax2 = axes(f, 'NextPlot', 'add', 'Color', 'none');
plot(ax2, 1:100, rand(100,1),'.','Color',[.6 .6 .6],'markersize',1)
plot(ax2, 1:100, rand(100,1),'.','markersize',49,'Color','k')
set(ax2, 'XTick', []);
set(ax2, 'XTickLabel', []);
ylabel(ax2, 'random numbers')

('NextPlot' set to 'add' acts like hold on and prevents properties such as YAxisLocation from being reset when you call plot).
