Are there any specific functions or methods in JPGraph that can help interpolate data points for a smoother line chart display?

When plotting a line chart in JPGraph, the data points may sometimes be too sparse, resulting in a jagged or choppy appearance. To create a smoother line chart display, you can use interpolation techniques to estimate intermediate data points between the existing data points. One way to achieve this is by using the "Spline" interpolation method available in JPGraph. 

// Create a new line plot
$lineplot = new LinePlot($data);

// Set the interpolation method to "Spline" for smoother curve
$lineplot->SetStepStyle('SPLINE');

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