Hello,
I've encountered a bug when updating a chart.
The initial chart is a line chart with 2 series & a set a predifined categories. xAxis type is set to 'category'.
Then I update the chart, setting the xAxis type to 'datetime', fillings series data with a x value (timestamp) to get a timeline chart
Here is a stackblitz: The xAxis is not showing proper formatted ticks
