Voorbeelden

In het volgende codevoorbeeld ziet u hoe u een drempelwaardelijn toevoegt nadat het grafiekbeheer is toegevoegd aan het ontwerpoppervlak. In de grafiek wordt een niet-terugkerende striplijn gebruikt om een berekening weer te geven van het gemiddelde van alle gegevenspunten in een reeks.
