How to enable required buttons and plot linear fit from group of graphs

I have created an where i want to enable required buttons based on the input given. I have the maxium limit of the required buttons. My app tells about the mangoes quantity in the basket and the plot are made for the estimation of the ripeness of mangoes. Where i have known about the maximum number of mangoes in basket. What i required is, 1) if i change my input, i don't want the import excel buttons to be deleted instead those should be diabled. 2) After plotting the graphs, i want to make the linear fit and the squareroot fit to the plotted group of graphs. i have attached my app and the excel file for the plot.

Hi Vahini,

From what I understood, you would like the import buttons to be disabled based on the input number.

You can use "app.Button.Enable" to toggle between the 'on' and 'off' states.

Here is an example code where I have 9 buttons, and based on the input number, the remaining buttons get disabled.

Function inputNumberFieldValueChanged(app, event)
    value = app.inputNumberField.Value;
    for i = 1:9
        if i > value
            app.(['Button_', num2str(i)]).Enable = 'off';
        else
            app.(['Button_', num2str(i)]).Enable = 'on';
        end
    end 
end

For the second part of your question, You can use the "polyfit" function to plot the linear and square fit graph.

Here is a link to the example for the same. https://www.mathworks.com/help/matlab/ref/polyfit.html#:~:text=0%2C4*pi)%3B%0Ay1%20%3D-,polyval,-(p%2Cx1)%3B%0Afigure

Note: Use the "hold" function to plot on the same graph/ UIAxes.
