// Setup a manual x-scale (We leave the sentinels for the
// Y-axis at 0 which will then autoscale the Y-axis.)
// We could also use autoscaling for the x-axis but then it
// probably will start a little bit earlier than the first value
// to make the first value an even number as it sees the timestamp
// as an normal integer value.

// Setup the x-axis with a format callback to convert the timestamp
// to a user readable time

// Create the line
$p1 = new LinePlot($datay,$datax);

// Set the fill color partly transparent

// Add lineplot to the graph

// Output line
