Any idea how to make the Paretosearch graph appear ?
This is what I used:
options = optimoptions('paretosearch','ParetoSetChangeTolerance',1e-7,...
'PlotFcn',{'psplotbestf', 'psplotmeshsize', 'psplotbestx'},'ParetoSetSize',200);
The optimisation is working and gives me the results. However, there is no graph appeard as it shown below:

Consult the documentation for the available plot functions. In partiicular, you find this statement there:
"For patternsearch only or paretosearch with a single objective: 'psplotbestf' | 'psplotmeshsize' | 'psplotbestx'"

Thank you Alan
I have done the same, but no graph was shown, the system is running and gives me the result with empty template. ((My problem is Nonlinear with Discrete Variables))
Do you think there is a technical issue with Matlab or could you give me an advice how to solve the problem.
Kind regards
options = optimoptions('paretosearch','ParetoSetChangeTolerance',1e-7,...
'PlotFcn',{'psplotbestf','psplotmeshsize','psplotbestx'},'ParetoSetSize',200);

Hakeem, please use only supported plot functions. Remove 'psplotbestf','psplotmeshsize','psplotbestx' as they are not supported. Please look at the documentation and use only supported plot functions for multiobjective functions.
