SfChart Zooming using Memory

[Julien Torrent]

Hi,

I'm trying to use an SfChart with a ChartZoomPanBehavior, but when i'm zooming the chart use a lot of memory.

I'using a FastLineSerie an the memory goes  up to 700MB with 400points.

Is there a solution to limit the memory consumption ?

Thanks

Hi,

is that on Android or IOS?

Hi,

It works well on Android and IOS, but when I'm running it on UWP ( both release and debug ) the zooming take a lot of memory.

The problem seems to be on UWP only.

Hi Torrent, 

 

We have analyzed the reported problem based on the provided information but the memory increase is not up to the level what you have mentioned. But, there will be a slight increase in memory while performing zooming and that too will back to normal on zoom out. 

 

We have prepared a sample and video based on this and you can download it from below link, 

Sample:Performance_Sample 

Video:Performance_Video
 

 

Please check the sample and let us know if you have configured anything else from our configuration we have done in the above sample. 

Also, we request you to provide some more details or if possible, please revert us with simple sample to reproduce this problem. It would be more helpful for us to provide a better solution sooner.

Hi,

I've tried with a DateTimeAxis, but it seems when I'm zooming too close to the minimum unit the memory fills up very quickly.

Thanks

Hi, 

After some tests, it only happens when i'm trying to zoom on a Chart that contains EmptyPoints. It happens only with UWP.

I've joined my test sample. 

Is there a solution to still use EmptyPoints ?

Thanks

Hi Torrent, 

 

Thanks for the update. 

 

We are able to reproduce this problem at our end. However, this can be resolved by replacing he FastLineSeries with FastLineBitmapSeries in UWP renderer project. 

 

You can download the modified sample from the below link, 

Sample:EmptyPointsZoom_FastLineBitmap
 

 

Could you please check the above sample and let us know whether this solution helps you to solve your problem at your end?
