How can one effectively troubleshoot and debug issues related to scaling and formatting time-based data in jpgraph using PHP?

Issue: When scaling and formatting time-based data in jpgraph using PHP, it is important to ensure that the data is correctly parsed and displayed on the graph. One common issue is incorrect formatting of the time data, leading to inaccurate scaling or labels on the graph. Solution: To effectively troubleshoot and debug these issues, make sure to properly format the time data before passing it to jpgraph. Use PHP's date() function to convert timestamps to the desired format, and ensure that the time data is correctly sorted before plotting it on the graph. Example PHP code snippet:

// Sample time-based data
$data = array(
    strtotime('2022-01-01'),
    strtotime('2022-02-01'),
    strtotime('2022-03-01'),
    strtotime('2022-04-01'),
);

// Format time data for jpgraph
$formatted_data = array_map(function($timestamp) {
    return date('Y-m-d', $timestamp);
}, $data);

// Create a new jpgraph instance
$graph = new Graph(800, 600);

// Add data to the graph
$lineplot = new LinePlot($formatted_data);
$graph->Add($lineplot);

// Display the graph
$graph->Stroke();
