I have a dual screen setup with the secondary monitor to the left of the primary. get(0,'MonitorPosition') returns
>> get(0,'MonitorPosition') ans = 1 1 1050 1400 -1679 1 0 1050
Why is the width of my secondary monitor zero? Bug?

The ability to use 'normalized' units in this manner to position a figure on only one of multiple monitors is not supported.
In some cases, the 'ScreenSize' property of the root object returns the summed width or height dimensions of the monitors. It is in these cases that the figure window may span the monitors, when created with the 'normalized' units.
One possible workaround is to get the coordinates of the screen where you want the figure window to be displayed, by using the undocumented 'MonitorPositions' property of the root object, which can be accessed with:
get(0,'MonitorPositions');Then you can position the figure using 'pixel' units instead of 'normalized'.
For example, executing the following:
f = figure('units','normalized','position',[0 0 1 1]); get(0,'MonitorPositions');returns:
1 22 1024 746 1025 0 1024 768To position the figure window on the active monitor, use the following command:
set(f,'units','pixels','position',[1 22 1024 746]);To position the figure window on the secondary monitor, use the following command:
set(f,'units','pixels','position',[1025 0 1024 768]);There is no direct method to move the Scope around but to obtain the Scope handles and then modify the handle properties as you would do for a generic MATLAB 'Figure' window. For the purposes of placing figures on a dual-monitor system, each monitor forms an area of a larger canvas formed by "joining" the two screens. Setting the 'Position' property appropriately will place the Figure (or Scope) on one screen or the other. Please follow the steps below to achieve this:
1) Open the model and keep the scope window open and move it the position on the monitor where you desire it appear every time.
2) Execute the commands
set(0,'ShowHiddenHandles','On') ; get(gcf,'Position')at the MATLAB command prompt. this will return a 1x4 position vector where the first two values are the x and y co-ordinates of the left-bottom edge of the Scope (with left-bottom corner of primary screen as origin). For instance you may obtain a row vector, say:
18 57 324 2393) Now the above vector defines the desired position of your Scope. To set this position, please add the code below to the 'PostLoadFcn' callback. To do so, right-click anywhere on the Simulink model window -> Select 'Model Properties' -> Go to 'Callbacks' pane -> in the 'PostLoadFcn' section add the following code:
a=find_system(gcs,'Name','Scope');set_param(a{1},'Open','on');shh = get(0,'ShowHiddenHandles');set(0,'ShowHiddenHandles','On');set(gcf,'Position',[18 57 324 239]);set(0,'ShowHiddenHandles',shh);Please note:
- If your scope block has a different name, please modify the line 1 accordingly.
- Also, in Line 4, the position vector needs to be set with the value that you obtain on your command prompt when executing Step 2 above.
