@nikita012 you can try with x-axis label rotation which can be done via UI Edit or through chart configuration
However, it is expected behavior that x-axis gets squished, it is removed. You can however, see the x-axis value when you hover over each data point in the chart.
If the above does not work out, you may have to share your current search and if the value on x-axis is
_time then use epoch time instead of string formatted time.
