Hi Alfie, 
 
Greetings, we have analyzed your requirement and you can achieve this by using Trendlines for series as per the below code snippet. 
 
Code snippet 
<syncfusion:FastLineSeries XBindingPath="Date" 
 
YBindingPath="Value"  Interior="#7F7F7F" ItemsSource="{Binding StockPriceDetails}"> 
 
<syncfusion:FastLineSeries.Trendlines> 
 
<syncfusion:Trendline Stroke="Black" Type="Polynomial"/> 
 
</syncfusion:FastLineSeries.Trendlines> 
 
</syncfusion:FastLineSeries> 
 
Please refer below user documentation for more details about trendlines and its Polynomial type.  
 
 
Please let us know if you have any queries.  
 
Thanks, 
Muneesh Kumar G.

Is there anyway I can plot a polynomial without having the original data?

Hi Alfie, 
 
We have analyzed your requirement and we suspect that your requirement is to see only polynomial line in SfChart. You can achieve this by setting series’s Interior as Transparent as per the below code snippet.  
 
Code snippet 
<chart:FastLineBitmapSeries XBindingPath="XValue" YBindingPath="YValue" 
                                    Interior="Transparent"   ItemsSource="{Binding Data}"> 
                <chart:FastLineBitmapSeries.Trendlines> 
                    <chart:Trendline Type="Polynomial"/> 
                </chart:FastLineBitmapSeries.Trendlines> 
            </chart:FastLineBitmapSeries>

If your requirement different from this, please give more information (pictorial representation) about your requirement that would be helpful for us to give better solution in this.  
 
Thanks, 
Muneesh Kumar G.
