SfChart: change interval and update immediatly

[p.b.]

Hello,
I'm using the SfChart to plot some data, but only the last view seconds. To do so I set the minimum and maximum property of a DateTimeAxis.
When the minimum and maximum is change the chart does not change until the next data value is added. Is it possible to force the chart to redraw itself?

Thank you

Thank you for the answer. The work around works partially as the change interval method is called very rapidly and I'm not able to click a button anymore (3 charts, a timer with interval set to 1ms adds data. The actual timerinterval is a little slower)
Are there any other methods?

addition:
when using itemsSource = some ObservableCollection, which already contains elements, then those are not plotted. Any way to plot them anyway?

Dear Customer,

 

Thanks for the update.

 

We have analyzed the reported queries. You can change the minimum and maximum value dynamically, when before adding data in series. Also series items source changed adding data dynamically in observable collection.

 

Note : previous provided sample, we are used to List of collection. So we are not able to change the List of collection dynamically.

 

We have prepared the sample based on your requirement. You can download the sample in the following location.

 

Please let us know if you have require any further assistance on this.

Dear Karthikeyan V.,
The server that holds the file seems to be offline (files2.syncfusion.com), it gets resolved to 66.135.59.51 but the server does not respond.
Furthermore I am sorry to say that I have a problem understanding your english.
If I understand the first paragraph correctly it tells me that I first have to change the min/max and then add data. My question in the first post was about changing it without the need of adding new data, I am aware that it can be changed and is plotted the right way when new data is added.
Please excuse, but I was not able to understand the second sentence of the first paragraph.

Is a "List of collection" a List<ObservableCollection>? Or just ObservableCollection?

Regards
Peter Burkert

Sorry for inconvenience caused.

Query 1: change interval and update immediately

We are glad to inform you that we have fixed this issue and taken a patch dll for the same. You can download the patch dll from the below link.

$systemdrive:\ProgramFiles\Syncfusion\EssentialStudio\11.2.0.25\SDK\References\CommonConfigurationeutral

This fix will be included in our next upcoming main release which will be available in August.

Query 2: when using itemsSource = some ObservableCollection, which already contains elements, then those are not plotted

We have analyzed the reported issue. We are not able to reproduce the issue with our sample. Can you please check with the sample in the following location? If you still face the problem, please revert us by modifying the sample based on your application along with replication procedure. This would be helpful for us to serve you.
