I've recently run into a dilemma while searching for icon ideas for sorting UI elements. The issue is that the icons for sorting items in ascending order by price and ascending by name (alphabetical order)'s icons that have arrows will not be consistent.
To be more specific, an icon indicating alphabetical order might have an icon with "A" on the top and "Z" on the bottom, with an arrow pointing downwards, indicating A to Z order:
Conversely, assuming I want to use the same design and concept with characters to the left, an icon indicating ascending by price (cheapest to most expensive) will have a dollar sign to the left, however the arrow will be pointing upwards, indicating the highest price on the bottom and the lowest price on the top:
These two similar sort types will have opposite-pointing arrows which seems inconsistent, icons that represent similar things should be similar, correct?
So I guess my question is: what other approach can I take to make arrows that represent similar sort types point in the same direction, if any?
