is there anyway to set the axis 'invisible' in App Designer?
similiar is 'axis equal'....
I looked around in the link below but could not find anyway to do that.

Do you want the axis off or equal? Using axis equal will not turn the axis off.
Try adding this line, modifying the axis handle to match your name.
axis(app.UIAxes,'off')

Add the command I shared earlier in the startupFcn callback

a new problem becomes that, if add command:
axis(app.cylinder_plot,'off')
axis(app.cylinder_plot,'equal')
to the startupFcn, it is not availble to set the backgroud color by:
Color(app.cylinder_plot,'w') or app.cylinder_plot.Color='w'
is there any mistake with my operation?
Thanks!

That is correct. Turning the axis off prevents the background from showing.
In the Design View of app designer, try the following.
  1. Select your axes
  2. In the Axes Properties > Labels, remove the XLabel String and YLabel String
  3. In the Axes Properties > Ticks, remove the values in XTick and YTick
  4. If you want a box around plot, in Axes Properties > Box Styling select the Box checkbox. You can pick the box color there as well.
  5. You'll notice that the background color is already white (default)
In your startupFcn callback add
axis(app.UIAxes,'equal')
% if you don't want the black lines for the axes, include:
app.UIAxes.XColor = 'w';
app.UIAxes.YColor = 'w';
