App Designer - Trying to modify a plotted axes line on a (figure with UIControls) called from the app.

1 Ansicht (letzte 30 Tage)
I'm trying to build an interactive figure that when the check box is checked or uncheck it displays the intended line or deletes the line. Delete can mean hide too. I can get the figure to display just fine but when I check/uncheck the checkbox I get
"Not enough input arguments"
for
line(axi,'XData',Time,'YData',Data1,'LineStyle','none');
Here's the whole thing
function buildUIFigure(~) % Need the ~ instead of app.
f = figure('Name','Data Selection','Position',[0 0 1100 900]);
% CheckBox1 Label
uicontrol(...
'Parent',f...
'Style','text',...
'Position',[55 650 120 20]...
'HorizontalAlignment','left',...
'String','First Check Box',...
'FontSize',14,...
'FontWeight','bold');
% CheckBox1 UIControl
CheckBox1 = uicontrol(...
'Parent',f,...
'Style','checkbox',...
'Position',[180 652 15 15],...
'CallBack',@VisualizeData,...
'Value',1);
ax = axes(...
'Parent',f,...
'Position',[0.25 0.1 0.7 0.85],...
'box','on');
line(Time,Data1,'Color','k');
drawnow
uiwait(f) % Wait for the user to close figure before moving on.
function VisualizeData (CheckBox1,Time,Data1)
axi = gca;
DispCheckBox1 = get(CheckBox1,'Value');
if DispCheckBox1 == 1
line(axi,'XData',Time,'YData',Data1,'Color','k');
elseif DispCheckBox1 == 0
% Trying to make it "disappear". Can't figure out how to delete the line altogether.
line(axi,'XData',Time,'YData',Data1,'LineStyle','none');
end
drawnow
end
end
I'm still reletively new to MATLAB and I might have picked a fairly ambitious app to make for my first! Lol. *cries

Well, in typical fashion, I semi-answered my own question...
function VisualizeData (CheckBox1,ax)
DispCheckBox1 = get(CheckBox1,'Value');
if DispCheckBox1 == 1
test = get(gca,'Children');
set(test(1),'Visible','on');
else
test = get(gca,'Children');
set(test(1),'Visible','off');
end
drawnow
end
This should work as long as the indexing cooperates.

I have a transfert function and I want to view if the system is stable by cheking its roots if their lenght is less than 1 but is does not go well and I don't understand where is the errorError in Untitled2ex42zabatawwalnoss (line 20)
x =
uicontrol('Parent',f1,'Style','text','Position',[81,1000,419,10],'value','systheme

slider
the hole code is
clear
close all
