Hi everyone,
I am fairly new to coding and have created a webpage with multiple
dashboards on it. However over time the memory keeps increasing, I have
pinned it down to when I draw each dashboard. I am doing this every 5
seconds.
Here is my code for one of the dashboards:
var chart, dashboard, rangeSlider, prevChart, prevDash, prevSlide;
function allChart() {
var data = new google.visualization.DataTable();
data.addColumn('datetime', 'Time');
for (var i = 0; i<siloArray.length; i++) {
data.addColumn('number', siloArray[i]);
}
data.addRows(allChartData);
var sliderOptions = {
controlType: 'ChartRangeFilter',
containerId: 'sChartFilter',
options: {
filterColumnLabel: 'Time',
ui: {
chartOptions: {
height:50,
width: '100%',
colors: colors,
chartArea: {
width: '90%'
},
hAxis: {
}
},
snapToData: true
}
},
}
var allOptions = {
chartType: 'LineChart',
containerId: 'sChart',
options: {
width: '100%',
height: 560,
focusTarget: 'category',
colors: colors,
legend: {
position: 'top',
maxLines: 5,
},
title: 'Number of Sessions based on Time',
chartArea: {
top: 100,
bottom: 60,
width: '90%',
height: '65%'
},
hAxis: {
title: 'Time',
},
vAxis: {
title: 'Number of Sessions',
format: '0',
maxValue: 6,
minValue: 0
},
},
view:{
}
}
var colArray = [];
for (var j = 0; j<siloArray.length; j++) {
colArray.push(j);
}
allOptions.view.columns = colArray;
if (allChartData.length == 1) {
allOptions.options.hAxis.ticks = [allChartData[0][0]];
sliderOptions.options.ui.chartOptions.hAxis.ticks = [allChartData[0][0]];
}
prevChart = chart;
prevDash = dashboard;
prevSlide = rangeSlider;
rangeSlider = new google.visualization.ControlWrapper(sliderOptions);
chart = new google.visualization.ChartWrapper(allOptions);
dashboard = new google.visualization.Dashboard(document.getElementById(
"sDashboard")).
bind([rangeSlider], [chart]).
draw(data);
if (prevDash) {
prevDash.visualization.dispose();
prevChart.visualization.clearChart();
prevSlide.visualization.dispose();
}
}
Any help is appreciated.
Lucas
