MATLAB Programming Fundamentals - MathWorks

TipWhen using a button control in a live script, consider setting the Run field for all

other controls in the live script to None. Then, the code only runs when the user clicks

the button control. This can be useful when the live script requires multiple control

values to be set before running the code.

Create Live Script with Multiple Interactive Controls

This example shows how you can use interactive controls to visualize and investigate

patient data in MATLAB®. The example plots the height versus the weight of either male

or female patients, and highlights the patients over a specified height and weight.

Use the interactive controls to specify the gender of the patients to plot, as well as the

threshold height and weight. To view and interact with the controls, open this example in

your browser or in MATLAB.

load patients

thresholdHeight = 68; % Slider with min=60, max=70, step=1

thresholdWeight = 132; % Slider with min=111, max=202, step=1

selectedGender = "Female"; % Drop down with options "Male", "Female"

overThresholdWeights = Weight(Gender==selectedGender & Weight>=thresholdWeight & Height>=thresholdHeight);

overThresholdHeights = Height(Gender==selectedGender & Weight>=thresholdWeight & Height>=thresholdHeight);

sp1 = scatter(Height(Gender==selectedGender),Weight(Gender==selectedGender),'blue');

hold on

sp2 = scatter(overThresholdHeights, overThresholdWeights,'red');

hold off

title('Height vs. Weight of ' + selectedGender + ' Patients')

legendText = sprintf('Patients over %d inches and %d pounds.',thresholdHeight,thresholdWeight);

legend(sp2,legendText,'Location','southoutside')
