Hello everybody,
I have a problem with my Matlab code. I would like to make a 2D plot with two y-axis with different axis limits. The created a proper function for the colors and I used them using the colororder function. However, it does not work with I wrote ylim function.
Do you know why?
I hope you can help me :)
Here my code:
figure
hold on
fontsize(12,"points");
x=[0,6,24,48,72];
xlabel('Time [h]');
yyaxis left
ylabel('Sugars [g/L]');
Glu1=[20.68,23.35,5.41,0.54,0];
errGlu1=[0.77,2.07,0.69,0.12,0];
Fru1=[5.19,5.55,2.07,0.93,0.78];
ylim([0 25])
yyaxis right
ylabel('Products [g/L]');
Et1=[0,0.16,7.51,9.37,8.20];
errEt1=[0,0.02,0.34,0.71,0.42];
Gly1=[0,0.2,0.3,0.36,0.37];
errGly1=[0,0.01,0.03,0.03,0.04];
ylim([0 12]);
plot(x,Glu1,'^-','LineWidth',2);
plot(x,Fru1,'^-','LineWidth',2);
plot(x,Et1,'v-', 'LineWidth',2);
plot(x,Gly1,'v-','LineWidth',2);
errorbar(x,Glu1,errGlu1,'LineStyle','none','Color','black');
errorbar(x,Fru1,errFru1,'LineStyle','none','Color','black');
errorbar(x,Et1,errEt1,'LineStyle','none','Color','black');
errorbar(x,Gly1,errGly1,'LineStyle','none','Color','black');
newcolors = [0.83 0.14 0.14
1.00 0.54 0.00
0.47 0.25 0.80
0.25 0.80 0.54];
colororder(newcolors)
hold off

Do you want to colors the individual plots according to the newcolors array?
If not, please specify the output that you want to obtain.

Note that in using ylim([0 25]) for the left yaxis, the upper cap of an errorbar data point is not visible. Adjust according to requirements.
%Data
x=[0,6,24,48,72];
Glu1=[20.68,23.35,5.41,0.54,0];
errGlu1=[0.77,2.07,0.69,0.12,0];
Fru1=[5.19,5.55,2.07,0.93,0.78];
errFru1= [0.13,0.57,0.41,0.14,0.06];
Et1=[0,0.16,7.51,9.37,8.20];
errEt1=[0,0.02,0.34,0.71,0.42];
Gly1=[0,0.2,0.3,0.36,0.37];
errGly1=[0,0.01,0.03,0.03,0.04];
figure
hold on
xlabel('Time [h]');
fontsize(12,"points");
yyaxis left
ylabel('Sugars [g/L]');
plot(x,Glu1,'^-','LineWidth',2);
plot(x,Fru1,'^-','LineWidth',2);
errorbar(x,Glu1,errGlu1,'LineStyle','none','Color','black');
errorbar(x,Fru1,errFru1,'LineStyle','none','Color','black');
ylim([0 25])
%Colorder for the left side
newcolors1 = [0.83 0.14 0.14
1.00 0.54 0.00];
colororder(newcolors1)
yyaxis right
ylabel('Products [g/L]');
plot(x,Et1,'v-', 'LineWidth',2);
plot(x,Gly1,'v-','LineWidth',2);
errorbar(x,Et1,errEt1,'LineStyle','none','Color','black');
errorbar(x,Gly1,errGly1,'LineStyle','none','Color','black');
ylim([0 12]);
%Colorder for the right side
newcolors2 = [0.47 0.25 0.80
0.25 0.80 0.54];
colororder(newcolors2)
hold off
Also, you can also specify the color of a line plot individually without needing to use colororder(), like you have done for the errorbars, as follows -
%Data
x=[0,6,24,48,72];
Glu1=[20.68,23.35,5.41,0.54,0];
errGlu1=[0.77,2.07,0.69,0.12,0];
Fru1=[5.19,5.55,2.07,0.93,0.78];
errFru1= [0.13,0.57,0.41,0.14,0.06];
Et1=[0,0.16,7.51,9.37,8.20];
errEt1=[0,0.02,0.34,0.71,0.42];
Gly1=[0,0.2,0.3,0.36,0.37];
errGly1=[0,0.01,0.03,0.03,0.04];
%Colors to be used for line plots
c = [0.83 0.14 0.14
1.00 0.54 0.00
0.47 0.25 0.80
0.25 0.80 0.54];
figure
hold on
xlabel('Time [h]');
fontsize(12,"points");
yyaxis left
ylabel('Sugars [g/L]');
plot(x,Glu1,'^-','LineWidth',2,'Color',c(1,:));
plot(x,Fru1,'^-','LineWidth',2,'Color',c(2,:));
errorbar(x,Glu1,errGlu1,'LineStyle','none','Color','black');
errorbar(x,Fru1,errFru1,'LineStyle','none','Color','black');
ylim([0 25])
yyaxis right
ylabel('Products [g/L]');
plot(x,Et1,'v-', 'LineWidth',2,'Color',c(3,:));
plot(x,Gly1,'v-','LineWidth',2,'Color',c(4,:));
errorbar(x,Et1,errEt1,'LineStyle','none','Color','black');
errorbar(x,Gly1,errGly1,'LineStyle','none','Color','black');
ylim([0 12]);
hold off
