Timeline charts smoothness

[SebF69]

## Help Request

### Problem description

I am currently using a timeline chart and I change the range of the X-axis (time range) from a few minutes to some hours or even some days. Then the x-axis scale is obviously adapted and so is the display: it shrinks data horizontally. If I have a continuous line of data, after moving the scale from 30 minutes to 24 hours, it is okay. BUT, let say I have several bars over different sets of minutes, it makes it discontinuous obviously and we see multiple bars displayed over this range of minutes. When I shrink the scale, so are the bars widths, it displayed something not smooth, with tiny pixels of white in between.

### Current Result

-Display over a 30 minutes-range: OK.

-Display over a 12-hours range: OK (it is still precise and we can notice there is a gap of time in between so it is good).

-Display over a 24hours range: NOT OK (the first previous bars are now closer to each other BUT we can notice a bit of white inside of it. It is not continuous).

### Expected solution

If bars are really close to each other, is it possible to make the whole set of them smoother without white in between OR to gather them inside a single plain bar which will split if we zoom back in ?
