How can non-numeric values in X or Y data arrays be addressed when using jpGraph in PHP?

Non-numeric values in X or Y data arrays can be addressed by checking each value before adding it to the data array. If a non-numeric value is encountered, it can be skipped or replaced with a default value to ensure that only numeric values are used in the graph. 

// Example code snippet to handle non-numeric values in data arrays for jpGraph

$data = array(10, 'invalid', 20, 30, 'error', 40);

$numericData = array();
foreach ($data as $value) {
    if (is_numeric($value)) {
        $numericData[] = $value;
    } else {
        // Handle non-numeric values, e.g. skip or replace with a default value
        // $numericData[] = 0; // Replace with 0
        // continue; // Skip non-numeric value
    }
}

// Use $numericData array in jpGraph to plot the graph
