how can release resource?

[cndv3996]

hi Guys,

i’m new comer, and i have a question, could you help?

i have a web page, which has a chart canvas & a slider,

say the slider has 100 positions.

when i pull the slider to another position,
ajax will load a PHP script with some data for canvasjs.

then i will new a chart, and fill in the new data:
var chart = new CanvasJS.Chart(“chartContainer”
…
and render.

after a few times,
memory usage of browser will keep increase,
and browser reponse will be slower & slower,

i think older data needs be released before i allocate a new chart?

how could i do it?
i just can’t find an answer in the document.

thank you.

sorry,

my mistake,

no need to release resource.

my mistake, and solved.

each time i pull slider, i add an “on” callback function repeatedly,
this made memory usage increase and browser slower.

not fault of canvasjs.

thank you.
