Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE news_report ( journalist_ID int, Event_ID int, Work_Type text )
TABLE: CREATE TABLE event ( Event_ID int, Date text, Venue text, Name text, Event_Attendance int )
TABLE: CREATE TABLE journalist ( journalist_ID int, Name text, Nationality text, Age text, Years_working int )

### Question ###
Return me a bar chart to show the average experience working length of journalists working on different role type, list by the Y-axis from low to high.

### Accurate SQL ###

SELECT Work_Type, AVG(Years_working) FROM journalist AS t1 JOIN news_report AS t2 ON t1.journalist_ID = t2.journalist_ID GROUP BY t2.Work_Type ORDER BY AVG(Years_working)
