MATLAB: Is the View property not updating correctly when I set the CameraPosition property

camerapositionMATLABview

I am setting the 'CameraPosition' property of my axes, but when I then examine the 'View' property using a "get" command, the angles have not been updated based on the new 'CameraPosition' values. How are 'CameraPosition' and 'View' related?

The 'View' property on the Axes is affected by the 'CameraPosition' property; however, it does not get updated automatically when you call "get" on the 'View' property. When you call "get" on the camera properties, however, it does update all relevant fields (including 'View'). This is why some outputs from

>> v = get(gca, 'View')

do not shown the correct, updated values.

To avoid this issue, you can add the following command before executing 'get(gca, 'View')':

>> drawnow

This will force an update of all fields (which will cause 'View' to update based on the new values you set for 'CameraPosition', for example).

MATLAB: Is the Tag property of the parent axes not retained when using the IMSHOW function

This is expected behavior. The IMSHOW function internally creates a new plot. Since the axes "NextPlot" property to set to "replace" (the default), all the axes properties are reset (except for the 'Position' property) to their default values and all axes children are deleted before displaying graphics.

In order to change this behavior, set the "NextPlot" property of the axes to "add".

The MATLAB code incorporating this change is provided below:

load spine;
imshow(X,map);
set(gca,'Tag','spineImagehere')
get(gca,'Tag')
set(gca,'NextPlot','add')
imshow(X,map,'Parent',gca)
get(gca,'Tag') % Tag is retained

MATLAB: Does the app freeze when loading data to a Table in App Designer and MATLAB R2017b

This issue does not occur in MATLAB R2018a.

To workaround this issue in MATLAB R2017b, add some "pause" statements:

>> app.StartButton.UserData='stopped';
>> pause(1);
>> view(app.AnimAxes, 30,2)
>> pause(1);
>>
>> LoadData(app);
>> pause(1);
>> app.Brake_Table.Data(:,1) = app.Data11;
>> app.Brake_Table.Data(:,2) = app.Data12;
>> pause(1);
>> app.Brake_Table_2.Data(:,1) = app.Data21;
>> app.Brake_Table_2.Data(:,2) = app.Data22;
>> pause(1);
>>
>> app.ax_Carposplot.XLim = [0 10];
>> app.ax_Carvplot.XLim = [0 10];
>> app.ax_Caraplot.XLim = [0 10];
>> app.ax_SCplot.XLim = [0 10];
>> app.ax_SCplot.YLim = [-0.2 1.2];
>> app.ax_SCplot.YTick = [0 1];
>> app.ax_SCplot.YTickLabel = {'open', 'closed'};
