Custom Filters

Demonstrates simple and advanced Custom Filters, with realtime updates using SciChart.js, High Performance JavaScript Charts

This uses a simple custom filter to apply random noise to a line, then an advanced aggregation filter calculates the frequency distribution

Simple Custom Filters are great if you just want to apply some function to each y value. Just create an XyCustomFilter and set your function. If you want to significantly reshape your data, create a class that extends XyFilterBase


There are CustomFilter and FitlerBase types for each of the series types (xy, xyy, xyz, ohlc)

Complex custom filters do not have to output the same series type as they take as input.

If your filter takes a parameter, use a setter to call filterAll when the parameter is updated
