When we change the period of a graph with the "green icon calendar" for example changing from Day to Week, and then when we are coming back to a Day period, the graph is getting confused and not coming back to its original state.
For example, if you choose June the 22th, then you click on the green icon calendar and select week and then select back the day period then instead of coming back to June the 22th it will be June the 26th... rather than June the 22th.
