Hi I am using google charts API, im calling a pie chart here is the code
google.setOnLoadCallback(drawChart);
function drawChart() {
$.ajax({
url:
"http://X3/playeruptime/system/?class=PlayerUptime&method=playerUptimePie&data={%22start%22:%222017-05-01%22,%22end%22:%222017-05-23%22}";,
success: function(result){
var dat = JSON.parse(result);
var data = new google.visualization.DataTable();
data.addColumn('string', 'key');
data.addColumn('number', 'value');
data.addRows(dat);
// Set chart options
var options = {
'width':500,
'height':315,
is3D: true,
colors: [
"#64cc34",
"#ff0000"
],
animation: {
startup: true,
duration: 2000,
easing: 'in'
},
legend: {
position: 'right',
alignment:'center',
textStyle: {
fontSize: 35,
color: '#616161'
}
},
chartArea: {left: 0, top: 0, right:50, width: "100%",
height: "100%"}
};
// Instantiate and draw our chart, passing in some options.
var chart = new
google.visualization.PieChart(document.getElementById('AverageUptimePie'));
chart.draw(data, options);
var onNum = dat[0][1];
var offNum = dat[1][1];
I need to know how do I reload the data in the charts periodically without
redrawing the charts in the sense that I dont want the chart to disappear
once data has been reloaded
Is there a redraw method that updates data to what it should be without
deleting chart
Thanks
