how to plot two graphs using a matlab?

I am trying to plot lots of data in one figure, but I can't plot my last one(wattdis).

The plot for equation 'wattdis' can not be plotted in my figure. Could you point out what errors I have in my code?

data = readtable('dataform');

x1 = data.incidentenergy1;

x2 = data.incidentenergy2;

U238_MT102 = data.U238_MT102 * 516.79*10^-6;

U238_MT18 = data.U238_MT18 * 516.79*10^-6;

U238_MT2 = data.U238_MT2 * 516.79*10^-6;

C12_MT2 = data.C12_MT2 * 8.216*10^-2;

U235_MT18 = data.U235_MT18 * 3.799 * 10^-6;

U235_MT102 = data.U235_MT102 * 3.799 * 10^-6;

maxwell = (2 .* pi / (pi .* 0.026/10.^6).^3/2) .* (x1.^1/2) .* exp(-x1/(0.026/10.^6));

wattdis = 0.4865 .* (x1.^1/2) .* ((2.* x1).^1/2) .* exp(-x1); %% Watt distribution

loglog(x1,U238_MT102);

grid on

hold on

loglog(x1,U238_MT18)

loglog(x1,U238_MT2)

loglog(x2,C12_MT2)

loglog(x2,U235_MT18)

loglog(x2,U235_MT102)

title('cross section')

xlabel('Incident energy(MeV)')

ylabel('Macroscopic cross sectiob(b)')

legend('U238 MT=102','U238 MT=18','U238 MT=2','C12 MT=2','U235 MT=18','U235 MT=102')

yyaxis right;

semilogx(x1, maxwell)

yyaxis left;

semilog(x1, wattdis) %% I cannot plot this one.

holf off

Answer 1

[Voss]

semilog should be semilogx, and holf should be hold

% semilog(x1, wattdis)  %% I cannot plot this one. 
semilogx(x1, wattdis)
 
% holf off
hold off
