Using opencpn currents data on android

[Deskofjk]

Hi there-

I have a harmonics file showing currents data on my android running opencpn. I can see arrows showing direction. But I can't figure out how to see currents data at a different date. How do I do that? How do I see a graph for currents at one location? Thx!

Touch and hold at the base of a current arrow. Not to bad on a tablet of decent size, kind of hard on a phone. It takes a bit of practice placing your finger or thumb exactly right. If you phone or tablet can use a stylus it might be easier to press the right spot.
