Scatter graph, time on X-axis, how to show hours?

I made a temperature graph, temp on Y and time on X-axis.

(It’s a scatter graph)

I only see 12AM and 12PM marked on the X-axis, even though my data was for every half hour.

How to make the X-axis show labels for all the hours ?

thanks

Double click on the X-axis and change the Scale tab from automatic to fit your needs. See example screenshot (This is just a demonstration of how it works and not a solution for your special case).

Opaque, thanks that worked.
