The AutoRange algorithm in SciChart calculates the data-point position, It does not take into account the size of the pointmarker.
You can provide a little padding to the axis by setting the GrowBy property:
const yAxis = new NumericAxis(wasmContext); yAxis.growBy = new NumberRange(0.1, 0.1);
This means ‘Apply a padding of 10% to the top and 10% to the bottom of the YAxis.
Try a small number like 0.05 or 0.01 and see if it makes the visual appearance better.
