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
