Remove common factor from axis

Hey, I'm trying to remove the common factor from the axis of a plot.
This is what i'm doing. (its a custom color bar)
cX = [1 2];
cY = repmat(linspace(1,8e6,256),2,1).';
h.figure = figure;
h.panel = uipanel('Parent',h.figure);
h.axes = axes('Parent',h.panel);
h.surf = surf('Parent',h.axes,'XData',cX ,'YData',cY,'ZData',cY,'CData',cY);
set(h.surf,'Facecolor','interp','Edgecolor','none')
set(h.axes,'View',[90 90]...
,'XTick',[],'XTickLabel',[]...
,'ZTick',[],'ZTickLabel',[]...
,'YTick',(1:8)*1e6,'YTickLabel',{'1M','2M','3M','4M','5M','6M','7M','8M'}...
,'YLim',[min(cY(:)) max(cY(:))])
Now the final plot has
1M 2M ... 8M 1x10^6
along the axis
I would like the axis to just be
1M 2M ... 8M
without the common factor of 1x10^6
Can anyone help me achieve this.

Please use code formatting. See the "{} Code" button and the "? Markup" link.

Change the renderer from OpenGL to zbuffer.
set(gcf, 'renderer', 'zbuffer');
Why this fixes the problem, I really have no idea. But I encounter it a lot when I add dateticks to my axes. Not sure if it's intended behavior or a bug, but most renderers eliminate the factor when manual tick labels are added; OpenGL does not (or at least doesn't always).

Problem half sorted.
cX = [1 2];
cY = repmat(linspace(1,8,256),2,1).';
cZ = repmat(linspace(1,8e6,256),2,1).';
h.figure = figure;
h.panel = uipanel('Parent',h.figure);
h.axes = axes('Parent',h.panel);
h.surf = surf('Parent',h.axes,'XData',cX,'YData',cY,'ZData',cZ,'CData',cZ);
set(h.surf,'Facecolor','interp','Edgecolor','none')
set(h.axes,'View',[90 90]... ,'XTick',[],'XTickLabel',[]...
,'ZTick',[],'ZTickLabel',[]...
,'YTick',(1:8),'YTickLabel',... {'1M','2M','3M','4M','5M','6M','7M','8M'}...
,'YLim',[min(cY(:)) max(cY(:))])
Doing this i avoid the common factor, but i'd still like to know how to remove the 1x10^6 without changing the magnitude of the data
