Real Time Line Chart With Opposed Y Axis Ans Auto-Scroll

[Tareq Khan]

Hi

I am trying to create a real-time chart that looks like those that can be found on Yahoo (see attachment), i.e. the latest value is next to the opposed Y-axis and the Y-axis shows a max/min such that the graph does not attempt to cover any unused values.

The underlying collection that is bound to the series implements IBindingList and data items are simple added to this collection as they arrive.

I know I can achieve this type of effect by setting the Range/DateTimeRange myself. To do this though, I would have to set the Range info on every ListChanged event and maintain my own internal Max/Min values for my collection in order to get the values used range for the Y-axis.

Is there any way of suggesting to the chart control that it does this itself? Or am I doing the correct thing. I guess what I am asking is that is the above method that I have described the most efficient?

Many Thanks

Tareq

Hi Tareq,

Thanks for your interest in Syncfusion products.

We regret to let you know that currently we do not provide direct support to automatically bind the ChartAxesRange according to the real-time data. The method which you have suggested is the best way to achieve the scrolling effect in Chart Control.

I have attached a sample that illustrates setting DateTimeRange dynamically to achieve scrolling effect in this link below.

Please let us know if this meets your requirement. Thanks for your patience.
