Example file from Excel

Attached example file shows two simple line charts with many data points.
The top one has Text type X axis, while the bottom one has Date type X axis,
both rotated to 90 degrees.
The top one displays the axis labels for all of the data points making them
slip together, while the bottom one skips some to keep them readable.

Steps to reproduce:
    1. Open attached file

Actual results:
The top chart shows too many X axis labels, making them unreadable.

Expected results:
The top chart should skip the display of some X axis labels, just like the
bottom one does.
