Is it possible to perform calculations within the same PHP script and use the results in a plot call, or is there a separate calculation environment in PHP?

In PHP, it is possible to perform calculations within the same script and use the results in a plot call. You can calculate the values you need and store them in variables before passing them to the plot function. This allows you to perform any necessary calculations within the same PHP script before plotting the data.

<?php

// Perform calculations
$value1 = 10;
$value2 = 20;
$result = $value1 + $value2;

// Plot the results
plot($result);

// Function to plot the data
function plot($data) {
    // Plotting logic here
    echo "Plotting data: " . $data;
}

?>
