我正在准备一个GUI,通过在两个不同轴上的复选框选择来控制绘图的可见性。另外,用户应该从弹出菜单中选择Y向量。代码工作正常(可能更优雅),但我有自动刷新情节的问题。目前,如果我绘制并随后从弹出菜单中选择不同的Y值,则必须取消选中并重新勾选要在绘图中进行更改的复选标记。如何选择(复选标记),如何自动刷新绘图?任何帮助是非常赞赏:不断更新GUI绘图
这是我的代码:
% --- Executes on pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
X=[1 2 3 4]
Y1=[10 20 30 40]
Y2=[-1 -2 -3 -4]
handles.X=X;
handles.Y1=Y1;
handles.Y2=Y2;
guidata(gcbo, handles);
UnitFcn(handles)
% --- checkbox function on/off
function C = OnOffStr(D)
OffOn = {'off', 'on'};
L = (D ~= 0) + 1; % 0/FALSE => 1, anything else => 2
if length(L) == 1
C = OffOn{L}; % Reply a string
else
C = OffOn(L); % Reply a cell string
end
function UnitFcn(handles)
Y1=handles.Y1;
for p = 1:numel(plotdata)
Unit = get(handles.popupmenu1,'Value');
if (Unit==1)
Y(:,p)=Y1(:,p);
elseif (Unit==2)%
Y(:,p)=Y1(:,p)*100;
end
end
handles.Y=Y;
guidata(gcbo, handles);
PlotFcn(handles)
function PlotFcn(handles)
X=handles.X;
Y=handles.Y;
Z=handles.Y2;
%Plot in Axes 1
set(handles.axes1, 'NextPlot', 'add');
handles.plot1 = plot(X,Y,'visible','off','LineWidth',2, ...
'color', [0 0 0],'linestyle', '--', 'parent', handles.axes1);
%Plot in Axes 2
set(handles.axes2, 'NextPlot', 'add');
handles.plot2 = plot(X,Y2,'visible','off','LineWidth',2, ...
'color', [0 0 0],'linestyle', '--', 'parent', handles.axes2);
guidata(gcbo, handles);
% --- Executes on button press in checkbox1.
function checkbox1_Callback(hObject, eventdata, handles)
set(handles.plot1, 'Visible', OnOffStr(get(hObject,'Value')));
% --- Executes on button press in checkbox1.
function checkbox1_Callback(hObject, eventdata, handles)
set(handles.plot2, 'Visible', OnOffStr(get(hObject,'Value')));
% --- Specify unit in popupmenu1.
function popupmenu1_Callback(hObject, eventdata, handles)
UnitFcn(handles)
function popupmenu1_CreateFcn(hObject, eventdata, handles)
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end
这是一个简化的代码和“对于p = 1:numel(plotdata)”是指一个矩阵,其中我有〜30个不同的地块。
