How can JPGraph handle different data point frequencies in a single line chart?

JPGraph can handle different data point frequencies in a single line chart by using the "SetAbsicssa()" method to explicitly set the X-axis data points for each line. This allows you to align the data points correctly even if they have different frequencies. 

// Create a new line graph
$graph = new Graph(400,300);
$graph->SetScale("textlin");

// Create line plot
$lineplot = new LinePlot($data_points);
$lineplot->SetColor("blue");

// Set X-axis data points for each line
$lineplot->SetAbsicssa($x_data_points);

// Add the line plot to the graph
$graph->Add($lineplot);

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