            Bug ID: 139149
           Summary: EDITING Chart category axis does not have “Interval
                    between labels” setting
           Product: LibreOffice
           Version: Inherited From OOo
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: Chart

attachment #167999 in Word 2013 and Writer 7.0

For a chart category axis MSO offers a setting “Interval between labels” which
allows to show only every nth labels, if there are many and the user only needs
some of those.
Chart does not have a similar setting, so it would be a nice addition for
interoperability to support such a feature in ODF (and later in OOXML
import-export + UI) too.

Steps to reproduce:
    1. Open attachment #167999 in Word and Writer

Actual results:
X axis has more labels displayed than Word. The X axis settings in Word has
“Interval between labels” set to 2, while there is no similar feature in the LO
UI.

Expected results:
This bug is only about implementing a similar LabelInterval property in ODF:
automatic (meaning 1) or custom value.
My Word 2013 seems to limit the custom value to 255 so for interoperability the
1-255 range would make sense in ODF.

Implementing OOXML support / UI would be topic for subsequent bugs.

LibreOffice details:
Attached screenshot is from:
Version: 7.0.0.3 (x64)
Build ID: 8061b3e9204bef6b321a21033174034a5e2ea88e
CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: Skia/Raster; VCL: win
Locale: en-US (hu_HU); UI: en-US
Calc: CL

There is no such feature in master either.
