Why do I receive an error when I try to change the transparency property of my barseries object in MATLAB 7.0 (R14)?

I execute the following code in MATLAB 7.0 (R14):

v1 = rand(81,1);            

c1 = [1 0 1];  

H1=histfit(v1);

set(H1(2),'Color',c1);

set(H1(1),'FaceColor',c1);

set(H1(1),'FaceAlpha',0.5);

I receive the following error message:

 "??? There is no 'FaceAlpha' property in the 'barseries' class."

The above code executed without errors in previous versions of MATLAB.

In MATLAB 7.0 (R14) and higher versions, the barseries object is of type 'hggroup' instead of type 'patch' as in earlier versions. The 'FaceAlpha' property that you would like to change is a property of a patch object which is now a child of the barseries object of type 'hggroup'.

You will need to modify your code to change the transparency property of a barseries object as follows:

v1 = rand(81,1);            

c1 = [1 0 1];                   

H1=histfit(v1);

set(H1(2),'Color',c1);

set(H1(1),'FaceColor',c1);

hpatch = get(H1(1),'children');

set(hpatch,'FaceAlpha',0.1);

Hi, is there something similar for the 'EdgeAlpha' property for histogram()? I receive the error message:

"There is no EdgeAlpha property on the Histogram class."

although the documentation suggests that EdgeAlpha should be variable for histogram.

Lucie, which release are you using?

I am facing the same problem FaceAlpha is not working in histfit command

subplot(3,4,1)
histfit(sgacc,317)
h1 = histfit(sgacc,317);
set(h1(1),'facecolor',[.48,.66,.87])                    
set(h1(2),'color',[.23,.29,.56])                 

hold on
histfit(sgacc+4.97e+22,317)
ha = histfit(sgacc+4.97e+22,317);
set(ha(2),'color',[.23,.29,.56])
set(ha(1),'facecolor',[.85,.85,.95])
hpatch = get(ha(1),'children');
set(hpatch,'FaceAlpha',0.1)
set(hpatch,'EdgeAlpha',0.1)

there is no error but I am not able to make second histfit plot transparent. Please help.

I am using Matlab2017b but I am unable to change barseries transparent using facealpha value
