Since 5.0.0 JKQTPlotter supports a line-compression algorithm (see `JKQTPSimplifyPolyLines()`). This allows to also draw very large datasets with sub-linear speed-decrease. The algorithm tries to not draw lines that are not visible, because they overlay each other. Using this mode we obtain these framerates for a two line-only graphs without anti-aliasing:
