Displaying hour data on an x-axis in a chart for large ranges (4+ weeks) shows no bars unless expanded

Describe the bug
If I have a chart with 24 hours for each day showing on the x-axis, if I expand the time range enough, eventually 0 columns/bars show unless I expand the panel

@cbruno10 do you have a reference snapshot I can use to debug this please?

When trying to render a large dataset, we are constrained by the amount of available chart space. In the example sent we're rendering a chart as 6 units of a full width container, which on a typical sized screen will not provide much space. If you zoom the panel you'll often be able to see the data points due to the increased viewport given to the chart.

I tried using the series sampling: 'lttb' strategy, but this doesn't seem to fix it - still nothing rendered.

We could look at some downsampling options, or could we just say that something with a large dataset should be given more display room?

@cbruno10 let's try replacing this with a heatmap chart.
