How do I make the second graph look like the first?

Hi I am writing code to automatically generate graphs from an excel file and am wondering how I miraculously made the first graph look how it is and not the second one.
<<

I would like the second graph to be all the same colour with different line styles. How do I do this? Here is an excerpt of my code
freqCounter=1; tempCounter=1; legendCounter=1;
firstDataSheet=2; sheet=firstDataSheet; PvsA=figure('Name','Power versus Current','NumberTitle','off'); SlopevsA=figure('Name','Slope (W/A) versus Current','NumberTitle','off'); cmap=colormap(lines(combinations));
for k=1:combinations
%need to modify the right hand side of the colon to find end of the %data
Current= xlsread(path,sheet,['B2:B' num2str(unique+1)]); PeakPower= xlsread(path,sheet,['E2:E' num2str(unique+1)]); beepboop=xlsread(path,sheet,['H5:H' num2str(unique+1)]);
offsetLambda=xlsread(path,sheet,'H2'); deltaT=(beepboop-offsetLambda)/lambdaK; %pre offset offset=deltaT(1); deltaT=deltaT+offset*-1;
Slope=PeakPower/Current;
figure(PvsA) yyaxis left plot(Current,PeakPower) hold on yyaxis right plot(Current(4:end),deltaT) hold on
figure(SlopevsA) plot(Current,Slope) hold on
sheet=sheet+sheetsToSkip;
end
%adding labels to the graph figure(PvsA)
title('Peak Power versus Current and delta T vs Current') yyaxis left xlabel('Current (A)') ylabel('Peak Power (W)')
yyaxis right ylabel('delta T')

Interesting... it seems to be a feature of the yyaxis... I'll formulate an actual answer instead.

yyaxis automatically changes the linestyle and even inserts markers when plotting multiple lines. If you want to make the second plot appear as the first one, then I suggest you use yyaxis but hide one of the axes.
yyaxis left
plot(rand(10,10))
yyaxis right
set(gca,'ycolor','none')
You could also grab the default settings of the yyaxis in your first graph
cs=get(gca,'colororder');
ls=get(gca,'linestyleorder')
ans =
7×2 char array
'- '
'--'
': '
'-.'
'o-'
'^-'
'*-'
and then simply apply them after toggling to your second graph
set(gca,'linestyleorder',ls)
set(gca,'colororder',cs)
Note that the yyaxis by default only has one colororder and multiple linestyleorders, whereas the normal plot has one linestyleorder and multiple colororders. By default, the first linestyle is plotted with each color, then the second linestyle is plotted with each colors and so on... This behaviour is controlled by the colororderindex and linestyleindex.

If you want the plot to work exactly like the yyaxis does, then you have to change the colororder as well. The default yyaxis only has one color and multiple linestyles so as to match the yaxis color. The normal plot has mutliple colors and only one linestyle
axes;
get(gca,'colororder')
ans =
0 0.4470 0.7410
0.8500 0.3250 0.0980
0.9290 0.6940 0.1250
0.4940 0.1840 0.5560
0.4660 0.6740 0.1880
0.3010 0.7450 0.9330
0.6350 0.0780 0.1840
It seems the colororder is, by default, prioritized over the linestyleorder. Basically, the first linestyle is plotted with each color, then the second linestyle is plotted with each colors and so on... You can change this behaviour by playing around with the properties LineStyleOrderIndex and ColorOrderIndex.
