How to use loops to plot add graphs to a plot depending on checkbox selection

I have created a checkbox with 5 different selections and I can't figure out how to use a loop to plot a graph containing the data that's been selected below is the code i've got so far

fig = figure;
checkbox_USD = uicontrol(fig,'Style','Checkbox','String','USD','Position',[10 105 100 15],...
'Callback', @Selected_USD);

checkbox_EUR = uicontrol(fig,'Style','Checkbox','String','EUR','Position',[10 85 100 15],...
'Callback', @Selected_EUR);

checkbox_AUD = uicontrol(fig,'Style','Checkbox','String','AUD','Position',[10 65 100 15],...
'Callback', @Selected_AUD);

checkbox_CAD = uicontrol(fig,'Style','Checkbox','String','CAD','Position',[10 45 100 15],...
'Callback', @Selected_CAD);

checkbox_HKD = uicontrol(fig,'Style','Checkbox','String','HKD','Position',[10 25 100 15],...
'Callback', @Selected_HKD); 


function Selected_USD (h,eventdata)
plot_USD = get(h,'Value');
disp(plot_USD);
end
function Selected_EUR (h,eventdata)
plot_EUR = get(h,'Value');
disp(plot_EUR);
end
function Selected_AUD (h,eventdata)
plot_AUD = get(h,'Value');
disp(plot_AUD);
end
function Selected_CAD (h,eventdata)
plot_CAD = get(h,'Value');
disp(plot_CAD);
end
function Selected_HKD (h,eventdata)
plot_HKD = get(h,'Value');
disp(plot_HKD);
end
        

i have already created 5 different functions that plot each graph the code for each is more or less identical

function graph_function_AUD
AUD = readtable('exchange_ratesAUD.xlsx');
AUD.Date = datenum(AUD{:,1});              
AUD_array = table2array(AUD);              
plot(AUD_array(:,1),AUD_array(:,3));      
title('GBP/AUD Exchange Rate');
xlabel('Date');
ylabel('AUD');
yearly_tick =datenum(1999:1:2019,1,1);     
set(gca,'xtick',yearly_tick);
datetick('x','mmm/yyyy','keepticks');
xtickangle(90);                            
set(gca,'XMinorTick','on');

end

any help would hbe much appreciated :))

You can get the value of the checkbox number i with

v=fig.Children(i).Value

So maybe you can make a for loop like this:

figure()
hold on
for i=1:5
    v=fig.Children(i).Value
    if v==1
        plot ...
    end
end

(note that is your script checkbox HKD is child number 1 and USD is child number 5)

any idea how i can remove the plot when the box is deselected?

[Nathanael Durham]

So far i've got some code that succcesfully adds the data to the same plot however when the box is deselected, the plot stays on the graph

fig = figure;                                %creates checkbox with the currency selections
checkbox_USD = uicontrol(fig,'Style','Checkbox','String','USD','Position',[10 105 45 15],...
'Callback', @Selected_USD);        %callback allows a function to operate when box is selected

checkbox_EUR = uicontrol(fig,'Style','Checkbox','String','EUR','Position',[10 85 45 15],...
'Callback', @Selected_EUR);

checkbox_AUD = uicontrol(fig,'Style','Checkbox','String','AUD','Position',[10 65 45 15],...
'Callback', @Selected_AUD);

checkbox_CAD = uicontrol(fig,'Style','Checkbox','String','CAD','Position',[10 45 45 15],...
'Callback', @Selected_CAD);

checkbox_HKD = uicontrol(fig,'Style','Checkbox','String','HKD','Position',[10 25 45 15],...
'Callback', @Selected_HKD); 



function Selected_USD (h,~)%callback for 'USD' selection
checked_USD = get(h,'Value');

if checked_USD == 1
    graph_function_USD
    hold on
end 
end           
    


function Selected_EUR (h,~)  %callback for 'EUR' selection
checked_EUR = get(h,'Value');
if checked_EUR == 1
    graph_function_EUR
    hold on
end
end
function Selected_AUD (h,~)  %callback for 'AUD' selection
checked_AUD = get(h,'Value'); 
if checked_AUD == 1
    graph_function_AUD
    hold on
end
end
function Selected_CAD (h,~)  %callback for 'CAD' selection
checked_CAD = get(h,'Value');
if checked_CAD == 1
    graph_function_CAD
    hold on
end
end
function Selected_HKD (h,~)  %callback for 'HKD' selection
checked_HKD = get(h,'Value');
if checked_HKD == 1
    graph_function_HKD
    hold on
end
end

also the graph_function_USD is a seperate function i've made which produces the plot i'll show it below

function graph_function_USD
USD = readtable('exchange_ratesUSD.xlsx'); %loads excel file for USD exchange rates
USD.Date = datenum(USD{:,1});              %converts dates from string to serial date number
USD_array = table2array(USD);              %converts table to matrix
plot(USD_array(:,1),USD_array(:,3));       %plots date against exchange rate
title('GBP/USD Exchange Rate');
xlabel('Date');
ylabel('Comparative Exchange Rate');
yearly_tick =datenum(1999:1:2019,1,1);     %set ticks to occur in yearly intervals
set(gca,'xtick',yearly_tick);
datetick('x','mmm/yyyy','keepticks');
xtickangle(90);                            %rotate x-axis labels to prevent cluttering 
set(gca,'XMinorTick','on');
legend('USD')
end

I think you can use this script as an example:

close all
fig = figure;
checkbox_USD = uicontrol(fig,'Style','Checkbox','String','USD','Position',[10 105 50 15],...
'Callback', @Selected_USD);
checkbox_EUR = uicontrol(fig,'Style','Checkbox','String','EUR','Position',[10 85 50 15],...
'Callback', @Selected_EUR);
checkbox_AUD = uicontrol(fig,'Style','Checkbox','String','AUD','Position',[10 65 50 15],...
'Callback', @Selected_AUD);
checkbox_CAD = uicontrol(fig,'Style','Checkbox','String','CAD','Position',[10 45 50 15],...
'Callback', @Selected_CAD);
checkbox_HKD = uicontrol(fig,'Style','Checkbox','String','HKD','Position',[10 25 50 15],...
'Callback', @Selected_HKD); 

axes1 = axes('Parent',fig,...
    'Position',[0.184642857142857 0.11 0.720357142857143 0.815]);
box on
axis([0 10 0 50])
hold on
for i=1:5
    plot((1:10)*i)
end
while ishandle(1)

for i=1:5
    
    v=fig.Children(i).Value;
    if v==1
        fig.Children(6).Children(i).Visible='on';
    elseif v==0
        fig.Children(6).Children(i).Visible='off';
    end
    pause(0.01)
   
end
end
function Selected_USD (h,eventdata)
plot_USD = get(h,'Value');
disp(plot_USD);
end
function Selected_EUR (h,eventdata)
plot_EUR = get(h,'Value');
disp(plot_EUR);
end
function Selected_AUD (h,eventdata)
plot_AUD = get(h,'Value');
disp(plot_AUD);
end
function Selected_CAD (h,eventdata)
plot_CAD = get(h,'Value');
disp(plot_CAD);
end
function Selected_HKD (h,eventdata)
plot_HKD = get(h,'Value');
disp(plot_HKD);
end

[Nathanael Durham]

When i try using this i get the following error,

Unrecognized property 'Visible' for class 'matlab.graphics.GraphicsPlaceholder'.

Error in checkboxplottest (line 28)

fig.Children(6).Children(i).Visible = 'on';

Answer 3

[Stijn Haenen]

Which matlab version do you have? I have 2019a and it works.

What do you see if you typ in the command window:

fig.Children

and

fig.Children(6).Children

[Nathanael Durham]

it say's

% Invalid or deleted object.

[Nathanael Durham]

and i'm using r2019b
