How to plot 3 parameters on same axis having different values

Hi, I need to plot 4 parameters A,B,C and Y in one Fig for comparison A,B,C on x-axis and Y on y-axis.one parameter has small values 10^-29 due to which this parameters only appear at zero as a single line not looking proper to give some result. I tried plotyy and plot hold on.A,B,C and Y are matrices of 10*1.

You should try plotting the values using the logarithmic or semi logarithmic scale.

You can use plotyy function

yyaxis left
plot(x,blt,'r','linewidth',1.5)
yyaxis right
plot(x,tchp,'b','linewidth',1.5)
legend('blt','tchp')
yyaxis left
xlabel('Radial Distance')
ylabel('BLT')
yyaxis right
ylabel('TCHP')

There is one disadvantage of this above function. You can not add more than 2 axis. TO add lots of X axis on your plot, use this function from file exchange https://in.mathworks.com/matlabcentral/fileexchange/9016-addaxis

plot(x,blt,'r','linewidth',1.5);
addaxis(x,tchp,'b','linewidth',1.5);
addaxis(x,mld,'k','linewidth',1.5);
addaxislabel(1,'BLT');
addaxislabel(2,'TCHP');
addaxislabel(3,'MLD');
legend('BLT','TCHP','MLD');
