Recommended ordinal values throws an error

[samuelhafsteinsson]

In the documentation about ordinal values: https://unovis.dev/docs/guides/tips-and-tricks/#displaying-ordinal-values

It is recommended to use a NumericAccessor with a StringAcessor in the tickFormat to get an ordinal scale.
However the documentation show that the following code snippet should work:

const categories = ['A', 'B', 'C', 'D', 'E']
const tickFormat = (tick: number) => categories[tick]

A problem with that snippet is, the tick can be a float and thus the code will throw an error as it cannot index the array with a float.
The fix I implemented is using Number.isInteger as so:

const categories = ['A', 'B', 'C', 'D', 'E']
const tickFormat = (tick: number) => {
  if (Number.isInteger(tick))
   return categories[tick]
  return ''
}

Versions:

"@unovis/ts": "^1.4.1"
"@unovis/vue": "^1.4.1"

Thanks for pointing this out @samuelhafsteinsson! The problem can be solved by providing a tickValues array to the Axis component explicitly: https://unovis.dev/docs/auxiliary/Axis#set-ticks-explicitly. We'll need to update the docs to mention it.
