How can I turn off the automatic plotting when using bayesopt

I used the bayesopt to help me obtain proper hyperparameters of SVM. However, since many different SVMs are needed, the bayesopt is called in a loop, like

for i = 1 : N
    ...
    results = bayesopt(minfn,[sigma,box],'IsObjectiveDeterministic',true,...
    'AcquisitionFunctionName','expected-improvement-plus', 'Verbose',0);
    ...
end

Thus the automatic plotting by the function baysopt is undesirable. And I also think it made the run time of the code longer, did it?

I have faild to find any input argument to handle this. Here I paste the code fragment in BayesianOptimization that is related:

function this = runSerial(this)
            ...
            this = callPlotFcn(this, 'initial');
            ...
            while ~optimizationFinished(this, iteration)
                % Maybe print verbose line
                ...
                % Do a function evaluation and record results
                ...


                % Choose next point

                % Update timing, plots and output

            end
            ...
            this = callPlotFcn(this, 'done');
            ...
end

Can I just prevent the Class from calling "callPlotFcn"?

Hi,

see this link to change the behavior of plot. For your purpose:

'PlotFcn', []

should work.

See also the Verbose option to get rid of the text messages / tables.

Best regards

Thank you very much. I didn't read the document carefully. I noticed "Verbose" but missed "PlotFcn". Thank you again for your help..
