Ok, I can work with that.
thanks

Tried a different approach, works great :)

if(charts[key]==undefined){
   //create chart....
   charts[key]=chart;		
}else{
   chart = charts[key];
   chart.options.data[0].dataPoints=points;
}				
chart.render();

Ok, I will try that.

What is consuming memory, the chart objects or something about the canvas?

Great, thanks.

Sometimes the forum doesn’t send emails after the replies :/

Hi,

Are you planning to implement this using canvas.toDataURL or using a script in the server?

Br,

[Daniel Silva]

It’s working great, excellent support as always.
Thanks

It’s working great, many thanks.
Unfortunately I had to stop the development of the reports because of another project, but I expect to buy and migrate all charts to CanvasJS in a few weeks.

Hi,

An alternative for what I need is saving the original object used to create the chart, modify this object, destroy the old chart and creating a new chart with the new object.
But that will increase memory in case of dashboards with many charts.

Thanks

Is possible to change the options object by another or I have to change the attributes one by one?
Thanks

Hi,
In the example I give is working great.
Then I tried to send all options by json to PHP, alter the theme, return also by json, change the chart options,render the chart, and the theme is not altered.

JS:

var chart = new CanvasJS.Chart("content",
{
	theme: "theme1",
	title:{
		text: "Changing Theme"
	},
	data: [
	{
		type: "column",
		dataPoints: [
		{ x: 10, y: 71 },
		{ x: 20, y: 55},
		{ x: 30, y: 50 },
		{ x: 40, y: 65 },
		{ x: 50, y: 95 },
		{ x: 60, y: 68 },
		{ x: 70, y: 28 },
		{ x: 80, y: 34 },
		{ x: 90, y: 14}
		]
	}
	]
});
chart.render();
var json=JSON.stringify(chart);

success = function(jsonObject) {
	chart.options=JSON.parse(jsonObject.chartOptions);
	chart.render();
};
jsonRequest(json,success);

PHP:

$s=json_decode ( $_REQUEST['json'] ,true);
$s['options']['theme']="theme2";
$response->chartOptions=json_encode ($s);

Br,
Daniel

If we could change any of the options and them call render would be great :)

Thanks

[Daniel Silva]

Its chart.options.theme=”theme2″;
Still doesn’t work :/

[Daniel Silva]

After a restart is all working great :/
Thanks
