the dawing method is not the same like the one shows here : https://demo.scichart.com/javascript-vital-signs-ecg-medical-chart-example

javascript-vital-signs-ecg-medical-chart-example shows that the history wave was "cleared" while drawing the new wave point.

You can do that yourself by just keeping the old data and overwriting it so that it looks like the example you provided.

ImPlot is an awesome library and it has an extensive feature set and customization options, but it just cannot cover all the possible use cases or visualization possibilities. Sometimes you just have to code it yourself.
