I want to access data and use for mutiple push buttons to plot graphs. For ImportdataButtonPushed import the data then for torqueButtonPushed I want to access and use data which imported in Import push button.
% Button pushed function: torqueButton
function torqueButtonPushed(app, event)
plot(app.UIAxes,[A.Speed_1_Total_WT1],[A.Torque_1_Total_WT1])
plot(app.UIAxes,[A.P_SigmaA_Total_WT1],[A.Eta1_1_Total_WT1])
However when I tried to plot graph it gives me error and I unable to plot subplot. Otherwise I have to add ten push buttons for ten plots. Using nested function how can use data to plot graph?
Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 410)
Error while evaluating Button PrivateButtonPushedFcn.

That doesn't answer my question.
What do you want? 10 axes, or 1? The total in either case would be 10 graphs.
And what part do you want to automate? You can write a small function that will create a uiaxes object and a button, but you will still have to type the text itself. Is that what you would want?
Try to make it easy for me to help you. It is easy for me to ignore this thread if it is more frustrating than rewarding. I doubt that is what you want.

You can use the callback functions of your buttons to replace the graphs and labels:
function torquevsSpeedButtonPushed(app, event)
plot(app.UIAxes,app.A.Torque_1_Total_WT1,app.A.Speed_1_Total_WT1)
title(app.UIAxes, 'Speed vs Torque vs Power')
xlabel(app.UIAxes, 'Speed (rpm)')
ylabel(app.UIAxes, 'Torque(Nm)')
zlabel(app.UIAxes, 'Z')
end

You can either use histcounts and use bar, or you can use histogram. As with any GUI: make sure you specify your axes (or in your case uiaxes) as the parent object.
