Hi! Almost perfect, only 2 request changes - the first one here, the second one in the comments.

1. The tooltip in the columnrange series is not showing the hours, see the screenshots

Not a mistake, but a small additional comment: try to avoid setting the constant max and tickInterval - letting Highcharts to calculate it automatically is usually a better choice.

max: 24 * 60,
tickInterval: 60,

2. Whenever you can, use format instead of formatter (better e.g. for JSON configs)

labels: {
    format: `{value}°${T_UNITS[currentTUnit]}`
},

[dqmrf]

Format will not work here because when you press the button: currentTUnit variable changes and axis text must change as well.

Then perhaps you should update the yAxis.labels.format on a button click as well? Only a few lines of additional code, but it'll work for more specific cases.

You don't have to change it now, but please keep it in mind - format is usually better than formatter. We had many users on support with problems when the formatter wasn't working in specific cases, e.g. when the chart config had to be a JSON string (no functions, only strings).
Soon you'll work with Highcharts core code, and build API and documentation, and you'll have to use format only.

ps. I can see the .attr() on the yAxis text - using yAxis.update({ title: { text: ... } }) is also better because you store all real values on the chart (with .attr, you only change DOM)

Okay. I'll keep that in mind.

Nice, good job 👏
