Hi everyone,
Kurt's help provided(https://gerrit.libreoffice.org/c/core/+/170666/9) me
that what should I be looking for and further validated that the changes
regarding the OOXML import/export are in right direction.
https://gerrit.libreoffice.org/c/core/+/170909
But, I couldn't figure out how the properties are being set(or what Kurt
said- "*changes are needed to pass the data down to the rendering in the
model-view-controller code.*")
as I am still getting errors regarding the UNO API while opening the XLSX
histogram file -
Unknown properties: The errors indicate that properties like "BinCount",
"OverflowBin", and "UnderflowBin" are not

Further, I also made entry for the MS Office like Format Axis option for
the Histogram Chart(which are commented as of now and also some changes
regarding ODF import/export are also commented)

SideBar UI area is shown below the chart Image -

perhaps have to *revert the entry* for the *BinRange* as this is only
related to the OOXML.
