I have an application that has 3 axes inside of it - named 'Top', 'Middle', and 'Bottom'. They are used to compare similar sets of data.
My application uses the standard startup callback startupFcn
I have a loop in startupFcn that goes through the 3 axes and attempts to set them all to standard font sizes and colors I define. I also embed handles to the axes in the App variables for shorter paths to properties I use commonly. Here is the code excerpt from startupFcn :
numLocations = numel( app.locations );
thisLocation = app.locations{loc};
thisAxes = getDMPart(app, 'axes', thisLocation);
shortAxes.handle = thisAxes;
shortAxes.title = title(thisAxes, [thisLocation, ' Chart']);
shortAxes.title.Color = app.axesTitleColor;
shortAxes.title.FontSize = app.axesTitleSize;
shortAxes.X = thisAxes.XAxis;
shortAxes.Y = thisAxes.YAxis;
shortAxes.X.FontSize = app.axesDataSize;
shortAxes.Y.FontSize = app.axesDataSize;
shortAxes.X.Label.String = 'Time';
shortAxes.X.Label.FontSize = app.axesLabelSize;
shortAxes.X.Label.FontWeight = 'bold';
shortAxes.Y.Label.String = 'Variables';
shortAxes.Y.Label.FontSize = app.axesLabelSize;
shortAxes.Y.Label.FontWeight = 'bold';
app.axesApp.(thisLocation) = shortAxes;
FYI, app.locations axesDataSize, and axesLabelSize are all constant properties in my app:
locations = { 'Top', 'Middle', 'Bottom' };
axesTitleColor = [1 1 1];
And axesApp is a public property of my app, set to a struct as follows:
However, after I run my App, the X and Y label sizes are 7.5!
The really bizarre thing, is when I try to troubleshoot and put a breakpoint at each assignment line in startupFcn - it works perfectly. The app pops up with the label at size 10 and the axes marks at size 8, as expected. The labels only shrink to 7.5 if I run normally, without breakpoints. I don't have anything else running in parallel while staruptFcn is running. Why would this happen?
