How do I change the default line style of plots generated using yyaxis?

I am plotting two sets of data with each set containing a 6 by 100 matrix. I would like the final plot to have 6 solid lines colored using the default color order. And 6 dashed lines colored using the default color order. However, when I use the command yyaxis left and yyaxis right, the default color and linestyles are changed. I've figured out how to override the colors by manually changing them using the plot command. I've tried to override the line style for the yyaxis right plot using 'LineStyle','--' in the plot command. Lines 1 through 4 come out the way I want, but lines 5 and 6 are dashed with the default line marker circle and triangle. How do I get rid of these default markers? Thank you in advance.

MATLAB version: R2017a OS: Windows 10 x64

figure(4) hold on

% colorVec = {'k', 'b', 'r', 'm', 'g', 'c'}; % linVec = {'--', '--','--', '--','--', '--'}; ,'Color', colorVec{i},'LineStyle',linVec{i} % delete( findobj(gca, 'type', 'marker') ); % yyaxis left %plot on left Y axis ax = gca;

co = [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]; set(groot,'DefaultAxesColorOrder',co)

for i = 1:nmat ax.ColorOrderIndex % plot(tvar,Ts1(i,:),'Color', co(i,:),'LineWidth',2) plot(tvar,Ts1(i,:),'Color', ax.ColorOrder(ax.ColorOrderIndex,:),'LineWidth',2) % hold on %hold commnd retains the current color order % plot(tvar,Ts2(:,:),'--','LineWidth',2,'MarkerSize',5) end

xlim([0 60]) grid on y_label = ylabel('Surface Temp [C]'); ax = gca; % current axes % ax.YAxis(1).TickLabelFormat = '%.2f'; ax.YAxis(1).Color = 'k'; %axis color

% figure(4) % ax.ColorOrderIndex = 1; %restarts the color order index before each plotting command

yyaxis right %plot on right Y axis for i = 1:nmat plot(tvar,driftT2(i,:),'Color', co(i,:),'LineStyle','--','LineWidth',2) end

y_label = ylabel('Thermal Drift [mrad]'); ax.YAxis(2).Color = 'b'; %axis color % ax.YAxis(2).TickLabelFormat = '%,d'; % ax.YAxis(2).Exponent = 0; hold off

You can do this using GUI inside of MATLAB commands. In the figure window go to, View > Property Editor. Then click on the line to want to modify. Although it is possible to do it through the code but if you only want to edit one figure, then this is a good option for you. Still, if you want to see the MATLAB code, you can go to File > Generate Code... and MATLAB will automatically generate the required code to create the figure with proper formatting.

Ameer, Thank you for your suggestion. When I edit the plot using the property editor I can indeed remove the markers. However, when I generate the code and implement the generated code into my script I am still not able to reproduce the graph without the markers.

I generated the source code for the same plot with the markers on the plot intact and compared the code to the generated code from the plot with the manually removed markers, and interestingly enough found that there were no differences. It doesn't look like the automatically generated code captures the removal of markers. I even tried running the function that was automatically created and that plot still reproduced the markers.

Any other thoughts?

[Ameer Hamza]

That's strange! Can you provide your script file along with related data? Only then we can find the actual problem.

[Eugene Cho]

I've attached the script that was generated for the manually modified graph to remove the plot markers. The script still produces the plot markers even though it was generated from a plot that has no markers. Thank you in advanced for your help.

Ameer trying what you had suggested I saw in the Plot Property Editor a Marker style 'none'. So I explicitly added this marker style to the plot command the phantom markers disappeared.

    plot(tvar,Ts1(i,:),'Color', co(i,:),'LineStyle','-','Marker','none',...
        'LineWidth',2,'Parent',axes1)

[Ameer Hamza]

By default this property is none. Good, if this explicit assignment wirked for you.
