오늘은 입력 받은 온습도 수치를 그래프로 그리는 게 목표다.

 

widget을 추가한 다음 widget 영역 내에서 우클릭해서 Promote to ... 항목을 선택한다.
이후 add
이후 Promote

새로 widget을 만들어서 우클릭하면 달라진 점이 보인다.

저거 선택까지가 의도한 바.

Data Base = excel

Data Table = excel 내의 sheet

 

====linux 상에서 sqlite db 설치 방법 =====

1. sudo apt update

2. sudo apt install sqlite3

3. sqlite3가 정상적으로 설치됐는지 확인.

 sqlit3

무수한 command의 향연...

cf)빠져나올 때는 .quit // 위에 올려보면 명령어 목록에 있음.

4. db를 만든다.

???

제대로 생성함.

5. db를 정상적으로 만들었는지 확인 sqlite> .databases

6.database command에서 나온다 sqlite> .quit

 

===Sqlite Browser 설치===

1.sudo apt install sqlitebrowser
