Scatterhistogram creates a figure with 3 axes. You can expecify where those 3 axes should be using the optional parent argument: scatterhistogram(parent,___) where parent can be a figure, panel, tab object, tiledchartlayout, or gridlayout.
Within your app figure, add a uipanel or one of the other supported objects. Then specify that object in the first argument of scatterhistogram.
Here's a demo that creates a figure instead of an app.
load patients
tbl = table(LastName,Age,Gender,Height,Weight);
fig = figure('Color',[.8 .8 .8]);
uip = uipanel(fig, 'Units','normalized','position', [.3 .3 .6 .6]);
s = scatterhistogram(uip,tbl,'Height','Weight');
If you prefer to use scatterhist, you can use the same workflow except that the parent argument is specified as name-value pair.
load fisheriris
x = meas(:,1);
y = meas(:,2);
fig = figure('Color',[.8 .8 .8]);
uip = uipanel(fig, 'Units','normalized','position', [.3 .3 .6 .6]);
s = scatterhist(x,y,'Parent',uip);
