[Lens] Ability to rotate axis tick labels in heatmap

[GitsBaud]

Describe the feature:
Hi, currently using kibana-7.5.0 and still not able to rotate the labels on X and Y axis for Heat map visualization. Is that something you are working on ?

Describe a specific use case for the feature:
Labels on X-axis are vertical so unreadable

thanks !

Hey there, thanks everyone for the request and involvement here, and sorry @GitsBaud for being late on asking the following questions but I really like to have a bit more context here to study the best approach for the various use cases:

1. what label types do you usually have on the horizontal axis? are those categories or numerical buckets?
2. what is the usual label size in characters?
3. what are your current layout constraints? are you ok to increase the width of the heatmap in favor of showing and reading correctly all the labels, or do you prefer limiting the required space sacrificing a bit the label readability (limiting the size, rotating the labels, alternating the labels)
4. can the label be shortened? does the label has the most important "bits" at the end/beginning/center of the text? or the label is not meant to be shortened?
5. can the label be formatted differently to reduce its size? like instead of showing Italy, Germany, France, you are ok to see IT, DE, FR? and/or similarly with numbers like 1K, 2K, 3K?
6. are all the labels always required to be shown? can you derive the label from the sequence if some labels are missing (like omitted due to the lack of space to avoid overlaps)?

@markov00 to answer your questions:

1. categories
2. quite short (mostly <10, can be a little more)
3. increasing the width a little. should be able to fit in 1 dashboard width. labels can rotated (with angle choice)
4. can be shortened, but perhaps allow show full on hover. beginning ususally most important
5. yes - abbreviations as optional (but won't work for filters, which in many cases is what we use. terms tend to be too many options to fit in heatmap
6. yes - should always be shown

Hello, just to add

This is limiting as we want to save dashboard space. In order to fully see the bottom axis, I need to expand the viz to the whole dashboard and thats still not great as it depends on the amount of characters.
