-----------------------------------
Summary: Sorting of double columns incorrect - the whole numbers
come first
Key: ZEPPELIN-3948
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3948
Project: Zeppelin
Issue Type: Bug
Affects Versions: 0.8.0
Reporter: Jens Rabe
Attachments: 2019-01-15 11_05_32-ReportVorbereitung - Zeppelin.png
When having a double value as an X axis, the chart is sorted incorrectly. e.g.,
if there are values 0.1, 0.2, ..., 1, 1.1, 1.2, ..., 2, there will first be 1,
2, 3, ..., then 0.1, 0.2, ...
Steps to reproduce:
# Start a new notebook with *spark* interpreter
# Submit the following:
{code:java}
sc.parallelize(0 until 100).map(x => (x.toDouble / 10.0, x)).toDF("x",
"y").createOrReplaceTempView("sortbug"){code}
# In the next block, use SQL and submit:
{code:java}
%sql select * from sortbug order by x{code}
# Switch the table to bar chart.
Expected: The bar chart is sorted by x correctly (0, 0.1, 0.2, ..., 1, 1.1, ...)
Actual: There is first 0, 1, 2, ..., 9, then 0.1, 0.2, 0.3, ..., 0.9, 1.1, 1.2,
...
