What specific changes did the user make to the code to address the incorrect display of time on the x-axis?

The issue with the incorrect display of time on the x-axis was most likely due to the incorrect formatting of the time data being passed to the chart. To address this issue, the user needed to ensure that the time data was properly formatted in a way that the chart library could interpret correctly. This could involve converting the time data to a specific format like UNIX timestamp or a string format that the chart library recognizes.

// Assuming the time data is in UNIX timestamp format
// Convert the timestamp to a readable format for the x-axis label
foreach($data as $key => $value) {
    $data[$key]['time'] = date('Y-m-d H:i:s', $value['time']);
}

// Pass the formatted time data to the chart library for display
// This will ensure that the x-axis displays the time correctly
