Hello,

I have a Blazor WASM app running Scichart JS. In attempting to get any of the filters working listed in the Filters API docs I am unable to build my application and get thrown an error.

As listed in Moving Average Filter Docs I import the XyMovingAverageFilter:

import { XyMovingAverageFilter } from ‘scichart/Charting/Model/Filters/XyMovingAverageFilter’;

Run npm install and build the application and I get the error:
Module not found: Error: Can’t resolve ‘scichart/Charting/Model/Filters/XyMovingAverageFilter’ in …

So far I have not run into any issues getting any of the Scichart JS APIs working in this manner.

Hello Sci Chart support!

I am attempting to apply a low pass filter to a FIFO chart. I have implemented the FilterAll() function successfully but I was wondering if there are examples on how to override the FilterOnAppend() function or how to make FilterAll() work for a FIFO chart.

Currently, when calling the FilterAll() method the program throws an invalid operation exception:

System.InvalidOperationException: ‘Data has been Appended to a DataSeries which is unsorted in the X-Direction. Unsorted data can have severe performance implications in SciChart.
For maximum performance, please double-check that you are only inserting sorted data to SciChart. Alternatively, to disable this warning and allow unsorted data, please set DataSeries.AcceptsUnsortedData = true. For more info see Performance Tips and Tricks at https://www.scichart.com/documentation/v4.x/webframe.html#Performance_Tips_&_Tricks.html

I do not want to allow unsorted data because I know it is not a good practice and even if allowing unsorted data, the chart stops updating after a few seconds.

It may be worth knowing that I am sampling data from a National Instruments’ data acquisition board. Sci Chart is helping me display this data, but I would like to display the filtered data as it is being queued.

If you could help me with this matter I would appreciate it!
Best,
Paola

Is there a way to extract the equation when using the linear or polynomial trend line filter api?
