Before I begin, I want to say that I am very new to Google's Graph API.
I want to be able to add dynamic icons to my line graph that would display
the wind direction. I've looked up how to do it, and I know it's possible.
But I don't know how to implement the
code in my script. Could someone please take a look at my code and tell me
how I would go about this?
<script type="text/javascript">
function Wind() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Time', 'Wind Speed'],
['15:45', <?php echo $wind_speeds[54]?> ],
['18:00', <?php echo $wind_speeds[63]?> ],
['20:15', <?php echo $wind_speeds[72]?> ],
['22:30', <?php echo $wind_speeds[81]?> ],
['0:45', <?php echo $wind_speeds[90]?> ],
['3:00', <?php echo $wind_speeds[99]?> ],
['5:15', <?php echo $wind_speeds[108]?> ],
['7:15', <?php echo $wind_speeds[117]?> ],
['9:30', <?php echo $wind_speeds[126]?> ],
['11:45', <?php echo $wind_speeds[135]?>]
]);
// Create and draw the visualization.
var ac = new
google.visualization.ComboChart(document.getElementById('Wind'));
ac.draw(data, { title: "Wind Speed and Direction",
curveType: "function",
width: 680, height: 260,
vAxis: {title:"Wind Speed (m/s)"},
hAxis: {title:"Time"},
legend: {position: 'bottom', textStyle: {fontSize:
12}},
});
;
}
google.setOnLoadCallback(Wind);
</Script>
