Weibull distribution plot x-axes scale is wrong

I am having problems with plotting a Weibull distribution for the variable: 'Cont_Wh_Wp'.

The x-axes shows weird scale, see figure below.

If I plot a histogram and and divide the x-axes by the number of point(662) the frequency on the x-axis seems to be better, see figure below.

The schape of both graphs are the same, but the x-axes is different. Below is my script where I plot the two grapgh.

%% Weibull  
[parmHat, parmCI]=wblfit(Cont_Wh_Wp);
scale= parmHat(1);
shape=parmHat(2);

figure(1)
X=linspace(min(Cont_Wh_Wp),max(Cont_Wh_Wp));
plot(X,wblpdf(X,parmHat(1),parmHat(2)))

%% Histogram
figure(2)
histogram(Cont_Wh_Wp,80)

Can someone help me with getting the x-axis on the right scale for the Weibull plot?

Try something like this —

%% Weibull  
[parmHat, parmCI]=wblfit(Cont_Wh_Wp);
scale= parmHat(1);
shape=parmHat(2);

figure(1)
X=linspace(min(Cont_Wh_Wp),max(Cont_Wh_Wp));
plot(X,wblpdf(X,parmHat(1),parmHat(2)))
xl = xlim;                                                  % Get X-Axis Limits (Range)

%% Histogram
figure(2)
histogram(Cont_Wh_Wp,80)
xlim(xl)                                                    % Set X-Axis Limits (Range) To The First Plot Values
