"Step by step" Bar Chart Rendering

Mon, 26 Jan 2026 16:26:21 GMT

Hi all,

I am using Google chart to render a bar chart. Say I have 12 months in Dimension (e.g. Jan-2014, Feb-2014, ..., Dec-2014) and the total sum of sales amount of each month in Expression.

Now I would like to to display the months (and their sales amounts) one after another (in order to simulate an animation). The following are what I have written in Script.js in an extension:

function googleCoreChartLoaded() {

Qva.AddExtension('CVL', AutoPlay);

}

function AutoPlay()

{

[…]

myChart = new google.visualization.BarChart(this.Element)

google.visualization.events.addListener(myChart, 'ready', sleep);

myChart.draw(view, options);

[…]

}

function sleep()

{

var start = new Date().getTime();

for (var i = 0; i < 1e7; i++)

{

if ((new Date().getTime() - start) > 1000)

{

break;

}

My problem is that, instead of showing the months (and their relevant sales amounts) one after another, only the last month (Dec-2014) is displayed on Qlikview (in Webview mode) after the above script has been executed.

Can anyone tell me what I have done incorrectly?

Thank you so much for your help!
