What role does the datetime column play in displaying data from a SQLite database using jpGraph in PHP?

When displaying data from a SQLite database using jpGraph in PHP, the datetime column may need to be formatted correctly in order to be properly displayed on the graph. To do this, you can use the strftime function in PHP to format the datetime column in the desired format before passing it to jpGraph for graphing. 

// Retrieve data from SQLite database
$query = "SELECT datetime_column, value_column FROM table_name";
$result = $db->query($query);

// Create arrays to store data for jpGraph
$dates = array();
$values = array();

// Format datetime column and store data in arrays
while ($row = $result->fetchArray()) {
    $dates[] = strftime("%Y-%m-%d %H:%M:%S", strtotime($row['datetime_column']));
    $values[] = $row['value_column'];
}

// Use jpGraph to create a graph with formatted datetime data
// Insert jpGraph code here
