I'm trying to create a button that displays values in two text boxs and plots two seperate graphs in the app designer so far the code I have is below. The program doesn't react when the button is pressed.
% Button pushed function: PlotSinCosButton
function PlotSinCosButtonPushed(app, event)
degrees = app.EnterDegreesEditField.Value;
% creates the variable for degrees.
radians = degrees.*pi./180;
% Converts degrees to radians.
yc = cos(radians);
ys = sin(radians);
plot(app.UIAxes,yc);
plot(app.UIAxes_2,ys);
yc = app.CosineoftheangleEditField.Value;
ys = app.SineoftheangleEditField.Value;
end

From your code, it appears that 'degrees' is a scalar
degrees = app.EnterDegreesEditField.Value;
so you are just trying to plot a single point. By default, it will not be visible on the axes. Change your lines to this
plot(app.UIAxes, yc, '+');
plot(app.UIAxes_2, ys, '+');
