You can activate Chandra’s second ability while you have an empty hand. If you do, you’ll draw one card.

For Chandra’s second ability, it doesn’t matter if the cards don’t go to your graveyard because of a replacement effect. For example, cards with madness discarded this way will still count toward the number of cards you discarded.
