- "fees per kb (Dash)" is 0.000001234323432 or say 7.9234234345345e-7 (just some random examples but you get the idea) and it's not human friendly imo
IMO it would be much better to have "fees per byte (duff)" like sat/byte in Bitcoin (should be integers, because you can't divide duffs or satoshis into smaller units);
- also "for fees per kb" - it's not clear is it avg or median, would be nice to have both if possible;
- would be nice to see avg/median for number of ins/outs for all/ps/non-ps txes - the last graph shows avg for all txes, so it's mostly a ps/non-ps ratio which is interesting too but says nothing about actual trends for various types of txes.
EDIT: also gray background and gray font is smth to tweak imo, it's hard to read the text...
