Problem solved, if someone wants an example, here is my code on the
playground.
function drawVisualization() {
// Create and populate the data table.
var data = new google.visualization.DataTable();
// Declare columns
data.addColumn('string', 'velocidade');
data.addColumn('number', 'altitude');
data.addColumn('number', 'altitude2');
data.addRow(['1', 2, 3]);
data.addRow(['1.2', 2.5, 3.2]);
data.addRow(['1.5', , 3.5]);
data.addRow(['2', 3, 4]);
data.addRow(['3', 3, 5]);
data.addRow(['4', 3, null ]);
data.addRow(['5', 3, 7]);
data.addRow(['6', 4, 8]);
// Create and draw the visualization.
new google.visualization.LineChart(document.getElementById('visualization'
)).
draw(data, { interpolateNulls:true,
curveType: "function",
width: 500, height: 400,
vAxis: {maxValue: 10}}
);
}
Thank you.
