Hi,

I want to build a SFChart with e.g. 500 DateTime DataPoints (Collection of 2-3 Days of Data with 5 Minutes-Intervall).

How can I do this with horizontal scrolling enabled ? Can you give me a sample Project please ?

X-Axis = DateTime (01.05.15 09:00) with 5-minute intervall

Y-Axis = Numerical

All data should be visible with scrolling.

Thanks

Helmut

Hi Helmut,

Thanks for using Syncfusion products

We would like to let you know that your requirement can be achieved by using Auto Scrolling Delta features. Using this feature, Chart is automatically scrolled to display the fixed range of data points at the end. You can also pan to view previous data points. We have also prepared a sample for your reference. Please find the sample from the following location:

Sample: http://www.syncfusion.com/downloads/support/forum/119021/ScrollDataSample1501137074.zip

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

Thanks,

Hi Helmut,

Thanks for the update.

We would like to let you know that auto scrolling is a feature used to display a fixed range of data points at the end of a data series and then it allows you to scroll to view the previous data points. It will automatically adjust to view the fixed data points at the end of data series even during live update. This feature is implemented with the intent to show the data points clearly in small size mobile devices and to view the invisible data points by scrolling.

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

Thanks,
Yuvaraj P
