Bar Graph with keyword

[tkaito]

I’d like to create the graph below with following data.

                :
2022-02-04 14:19:43,Positive
2022-02-04 14:19:53,Positive
2022-02-04 14:20:03,Positive
2022-02-04 14:20:13,Positive
2022-02-04 14:20:24,Positive
2022-02-04 14:20:34,Positive
2022-02-04 14:20:44,Positive
2022-02-04 14:20:54,Positive
2022-02-04 14:21:04,Zero
2022-02-04 14:21:15,Zero
2022-02-04 14:21:25,Zero
2022-02-04 14:21:35,Zero
2022-02-04 14:21:45,Negative
2022-02-04 14:21:56,Negative
2022-02-04 14:22:06,Negative
2022-02-04 14:22:16,Negative
2022-02-04 14:22:26,Negative
2022-02-04 14:22:37,Negative
                :

Using State timeline, I could get the graph that is close to the idea but with Count, like following.

Is there any way to remove the Count graph?

Using Filter by name in Transform option, I can remove the Count bar graph.
