            Bug ID: 142343
           Summary: VIEWING Chart with calculated floating values displays
                    broken data labels
           Product: LibreOffice
           Version: 5.2.0.4 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Keywords: bibisected, bisected, regression
          Severity: normal
          Priority: medium

Example file from Excel

Attached user-made file contains calculated (such as: K9 cell is =B10-B9; while
B9=B4-100 and B10=B5-100; and K9 is one data point in the chart) floating point
values. While the cells display the calculated values with one decimal digit,
the chart data labels display the full floating point values such as 0,4
becomes 0,400(manyzeroes)6.
In case of the K9 cell, replacing the B9 and B10 cells formula with static
values fixes the chart data labels precision.

Steps to reproduce:
    1. Open attached file or its ODS-saved version

Actual results:
Chart data labels display the floating point values with too many digits.

Expected results:
Data labels show the floating point values with one decimal digit.
