I'm designing the hover states for 2 charts, a bar chart and a line chart. Maybe I'm over thinking, but for both these charts I find there is an arrow alignment that would work better based on the type of the chart. Should they be point horizontally or vertically aligned?
For bar chart I think pointing horizontally would make sense at it doesn't cover the details on the bar. For the line chart I'm not sure which would be the better. What consideration should I make in order to decide these?
