Time_sec labels stuck together

I do following bar chart -

with mysql data source

SELECT
  time_sec,
  value,
  neg
FROM ..

But the problem that time_sec labels stuck together in to white thick line, and there is no any labels on mouse hover, I want to see this time labels then I hover on chart points, how can I achive that?

try

SELECT
  time_sec as time,
  value,
  neg as metric
FROM ..

I allready have (somefield as neg) how can I do this as metric ?

I try

SELECT
f1 as time_sec,
f2 as value,
f3 as neg,
‘neg’ as metric

This does not help

please post table schema and sample data as csv text here
