Y-value is not correct but aggregated for Scatter, Line, Bubble chart

[yoshiokatsuneo]

Issue Summary

Chart for Scatter, Bubble, Line.. does not show correct y-value when there are multiple data for the same x-value.

Steps to Reproduce

1. Run SQL for multiple data on the same x-value, like below.

select 1 as x, 1 as y
union all
select 2 as x, 1 as y
union all
select 3 as x, 1 as y
union all
select 3 as x, 1 as y

It should show y=1 for all value, but the chart show y=2 (=1+1) for x-value 3.

Y-value should not be aggregated for Scatter, line ,etc...
