Calc: x-axis is not shown in data ranges.

Hi all,

I’m trying to create a graph from two data series (x-values and y-values).

When creating a graph, type of graph doesn’t matter (I’ve chosen a lot of them), and then
selecting Data Ranges->Data Series->Add, no x-axis is shown so I can select ranges from the spreadsheet.

I tried installing the new version but nothing happened.

I don’t remind changing options.

Thank you in advance.

Please attach a sample file.
