Hi @Katerina_Rozmanova , from what I can determine from your screenshot, if you are trying to get the sum of estimated time from the new Time tracking feature, you need to set the Y-axis to ‘Time entry’ instead of ‘Time>Time in Custom Field’ (which counts the time that a task has remained with a certain custom field option being selected) which is something else.
Try the below setup if you are tracking time with the new time tracking feature which is available for Business and Enterprise plans:
If instead, you are tracking using your own number-type custom field, then choose ‘Custom Field’ and select your custom field from the list instead.
