Hi everyone, i was wondering if there is a way for a scope i use in a simulink model to automaticaly autoscale. Maybe from adding a code to its startfunction???

Hi Raldi,
assuming the scope blocks are open, the following piece of code does the autoscaling for you:
% find all scope blocks as MATLAB figures:
set(0, 'showhiddenhandles', 'on')
scope = findobj(0, 'Tag', 'SIMULINK_SIMSCOPE_FIGURE');
for i=1:length(scope)
% this is the callback of the "autoscale" button:
simscope('ScopeBar', 'ActionIcon', 'Find', scope(i))
end
set(0, 'showhiddenhandles', 'off')

To make the autoscale function automatically i created a matlab function with the code above. The code will be executed each certain period of time. In my case 3 seconds, i did it with this function and the block clock of Simulink. the function that i have created is this one: -------- function u=scope(y) % find all scope blocks as MATLAB figures: u=0; z=mod(y,3)==0 if(z==1) set(0, 'showhiddenhandles', 'on') scope = findobj(0, 'Tag', 'SIMULINK_SIMSCOPE_FIGURE'); for i=1:length(scope) % this is the callback of the "autoscale" button: simscope('ScopeBar', 'ActionIcon', 'Find', scope(i)) end set(0, 'showhiddenhandles', 'off') end
end ----------- Then, in the clock block i selected 1000 as decimation and i use this code in a "interpreted Matlab function" block just writting "scope" in the label "Matlab function". I drive the output of this function to a scope but this output is not really interesting.
best regards

By clicking the binocular button on the scope, perhaps?

I did not find the binocular button too

Add below piece of code in your 'StopFcn' callback function. When the simulation is completed, it will open and autoscale all the scopes in the model.
[EDITED TO WORK FOR MULTIPLE INPUT SCOPE]
bh=find_system(gcs,'FindAll','on','BlockType','Scope');
for x=1:length(bh) %close all scope
set_param(bh(x),'Open','off');
end
for x=1:length(bh)
set_param(bh(x),'Open','on');
fh=gcf;
AxesInScope = findall(fh,'type','axes');
for y=1:length(AxesInScope)
set(fh,'CurrentAxes',AxesInScope(y));
xlim('auto');
ylim('auto');
end
end

As your scope is reading 2 inputs, previous code was autoscaling only one graph keeping other as it is.
I have updated the code so that it can work for multiple input scopes.

Typically, when users describe this, they are happy with the Time Scope Block from DSP System Toolbox. Here is the link to the documentation.
Especially, as Raldi is working at a university in the field of Signal Processing, this product should be available. Note that previous versions used different names like Signal Processing Blockset or DSP Blockset.

i think there is another way, ill try to change its YLim throygh my gui and update it.

set(0, 'showhiddenhandles', 'on')
%current graphic object
scope=gcf;
%find Autoscale object
scale=findobj(gcf, 'Tag', 'uimgr.uisplittool_Autoscale');
%click this object
feval(get(scale,'Callback'),scale,[]);
%find PrintToFigure Menu
fig=findobj(gcf, 'Tag', 'uimgr.uimenu_PrintToFigure');
%Click this Menu
feval(get(fig,'Callback'),fig,[]);
set(0, 'showhiddenhandles', 'off')

This function:
simscope('ScopeBar', 'ActionIcon', 'Find', scope(i))
Doesn't seem to be supported anymore in MATLAB 2020b.
This seems to work:
allAxes = findall(gcf,'type','axes');
for x = 1:numel(allAxes)
axis(allAxes(x), 'auto y');
axis(allAxes(x), 'auto x');
end
