It’s possible to see that the first two users live on the same timezone ( Norway, GMT+2 ) while the third user lives on a different one ( Brazil, GMT-1 ). Generally speaking, too fine of a granularity is better than too coarse; while we can use grouping and pivoting to change a fine granularity to a coarse one, we have few tools to go from coarse to fine. You have two possibilities to fix this problem. We will use the combination of hue and palette to color the data points in scatter plot. 나는 그 날에 여분의 칼럼을 만들 수 있다는 것을 알고 있지만 적절한 x 축 레이블링과 x-limit 기능 (ts.
