Chart with two Y-axis without grid-lines

Postby Leo on Mon Jul 23, 2018 3:26 pm

Hallo APL/SharpPlot-Experten,
Meine Frage: Wie kann man die Y-Grid Linien der ALFSK-Achse Unterdrücken?

The strict way to remove Y gridlines on the second graph is to reset the YAxisStyle
      sp.YAxisStyle←0

before the second call to sp.DrawLineGraph on line [43]

However the cool thing you probably want to use is to synchronise the new Y axis tickmarks with the previous one by modifying the YAxisStyle:
      sp.YAxisStyle+←Causeway.YAxisStyles.Synchronised

Hello Nick,
Thank you for the note about synchronizing the axes.
SharpPlot is indeed a great graphics program.
Best regards
