Issues with SfGauge and SfChart in Listview

[Femil Shajin]

Hi,

I'm facing some issues with the Gauge and SfChart's ColumnSeries while using it in the listview, I have also attached the sample code in .rar format.

#1 In iOS - Gauge pointer value is not starting from 0 if the GaugeType is North.

#2 In Android - if we use recycle listview 'ListView(ListViewCachingStrategy.RecycleElement)'the charts in the listview cell's is not hide/show other cell's data. To Troubleshoot : Scroll to bottom and up in the listview.

#3 In iOS - if we use deafult listview'ListView(ListViewCachingStrategy.RetainElement)'chart's legends are duplicated and behaves weirdly. To Troubleshoot : Scroll to bottom and up in the listview.

If you use attached the sample code you can easily relate to the points mentioned above. Please revert back if more info is needed.

Hi Femil,

Thanks for contacting Syncfusion support.

Query1: In iOS - Gauge pointer value is not starting from 0 if the GaugeType is North.

Based on the provided Sample, we have found that the scale has assigned twice in CircularGauge. We have modified the provided sample and have attached below.

If the provided Sample does not meet your requirement, could you please modify the attached sample to reproduce the issue (if possible screenshots)?

Query2 & 3: In Android - if we use recycle listview 'ListView(ListViewCachingStrategy.RecycleElement)' the charts in the listview cell's is not hide/show other cell's data.
In iOS - if we use deafult listview 'ListView(ListViewCachingStrategy.RetainElement)'chart's legends are duplicated and behaves weirdly.

We are able to reproduce the reported issue and have logged a defect report for the issue. The fix for this issue is estimated to be available in our upcoming Volume 1, 2016 release, which is scheduled to be rolled out by the end of March, 2016.

Hi Nijamudeen,

I have updated the Syncfusion to Volume1 2016 buiild version 14.x.x.x. And I'm facing the following issues only in Android (Attached the sample code).

• Gauge is not aligned in center.
• Labels are not visible. (0 and 100)
• And animation for the needle movement is missing which was in previous version.

Is this due to the update? Is there a workaround for this?

Thanks,

Femil Shajin C
