Hi,

I was using a MATLAB app between two versions (R2020a and R2022a) and noticed the data type of uiaxes to be different between the two versions.

When I try to create a uiaxes and check the axis type using isa I am getting two different results.

In R2020a,

tmpAxes = uiaxes; % declare uiaxes
isa(tmpAxes, 'matlab.graphics.axis.Axes') % check against `axes` data type
% output is FALSE

In R2022a,

tmpAxes = uiaxes; % declare uiaxes
isa(tmpAxes, 'matlab.graphics.axis.Axes') % check against `axes` data type
% output is TRUE

Any possible reason this might be happening? Thanks in advance.

@Jayanth Suresh - I see the same behaviour with 2021a

>> tmpAxes = uiaxes; % declare uiaxes
isa(tmpAxes, 'matlab.graphics.axis.Axes') % check against `axes` data type
ans =
  logical

so perhaps this change was introduced in 2020b or 2021a.

I'm not certain offhand but I suspect that's a consequence of the changes made in release R2020b.
