Hi Ben
The GraphCreator is working fine togheter with the Oled LCD_SSD1351 component.
For some signals a high pass filter would be very useful.This filter would also remove an offset.
For the graph I have a Signal with either 500Hz or 2kHz sampling rate. It's simple to add a point.
Creating the DSP functions is also easy.
Question: Do I need a buffer or can I only work with one variable ?
or how can I just insert the filter in a simple way?

Hello,
You're on the right track. How about something like this?

Re: How to use GraphCreator with highpass filter
Hi Ben
The Highpass Filter is working nice. For a test I inserted a middle line (Baseline) in blue and the not filtered Signal in green.
So the green Signal goes out of range if there is a offset. The red stays in the middle.
The another picture is the result.
Green = not filtered
Red = filtered
Blue = Zero line (Baseline)
