I've also tried use options: charsMap: '0123456789', but it does not work!

If you use a custom png with only the numbers and set the charsMaps to numbers only, it will only display numbers. But as you will have only 10 chars, the animation will be short.

$('.my-spliflap').splitFlap({
    image:          'images/chars-numbers.png',
    charsMap:       '0123456789'
});
