Assigning a line plot object to a global property doesn’t retain it after the object is deleted
Is there a reason why when I delete a plot of a multiplot graph and assign it to a global (public) property it doesn’t retain it.
ax=app.UIAxes; % My plot is on a UIAxes
t = ax.Children(1) % Get the last plot
app.myPlot=t % myPlot is a Global property
delete(t);
app.myPlot
app.myPlot shows:
ans =
handle to deleted Line
so instead I have to access all the properties of the line individually and assign to a struct.
s = struct;
s.X=t.XData;
s.Y=t.YData;
s.Cl=t.Color;
s.DN=t.DisplayName;
s.Ls=t.LineStyle;
s.Lw=t.LineWidth
s.M=t.Marker;
app.myPlot=s;
