How can the code be optimized to ensure proper data retrieval and display in the PHPlot graph?

To optimize data retrieval and display in the PHPlot graph, you can ensure that your query retrieves only the necessary data and that the data is properly formatted before being passed to the graph. Additionally, you can optimize the graph settings and styling to improve performance and readability. 

// Example of optimizing data retrieval and display in PHPlot graph

// Ensure that the query retrieves only the necessary data
$query = "SELECT date, value FROM data_table WHERE category = 'example'";
$result = mysqli_query($connection, $query);

// Format data for PHPlot
$data = array();
while ($row = mysqli_fetch_assoc($result)) {
    $data[] = array($row['date'], $row['value']);
}

// Set up PHPlot graph
require_once 'phplot.php';
$plot = new PHPlot(800, 600);
$plot->SetDataValues($data);
$plot->SetTitle('Example Graph');
$plot->SetXTitle('Date');
$plot->SetYTitle('Value');

// Display the graph
$plot->DrawGraph();
