Ampler Charts can relabel a date X-axis in another format — quarters, years, months, or a custom pattern — without touching the underlying data.
Quick answer: Select the X-axis, then use Date format in the Format menu to switch the labels to quarters, years, or another pattern; the axis relabels while the dates stay the same.
How to use it

Select the X-axis and pick a date format such as quarters or years.
- Select the X-axis, then use Date format to change the labels to quarters, years, or another format.
- Your chart is updated with the new date formatting.
Formats include day (dd.MM.), month (M / MM / MMM / MMMM), month-year (MM/yy), quarter (Q’Q / QQQ), and year (yy / yyyy).
When to use it
Change the format to match the cadence of the story — quarters for a quarterly trend, years for a long horizon — so the axis reads at the level the point is made and doesn’t crowd.
How consultants use it
On a time axis the label cadence is a deliberate choice, and getting it right is a readability decision consultants make on purpose. A few practices apply:
- Label the span, not every date: grouping a long series into quarters or years reads more clearly than a dense run of individual dates
- Match the cadence to the data: align the unit to how the metric moves — months for monthly figures, quarters or years for a long horizon — and avoid over-fine ticks that crowd the axis
- Standardise it across the deck: using the same date format on every time-series chart lets a reader compare them without re-reading the axis each time
Setting the date format lets a time axis speak at the story’s cadence and stay legible.
Tips & best practices
- Use quarters or years to de-clutter a long time axis instead of deleting labels.
- The format changes the labels only — the underlying dates are unchanged.
- Keep the same date format across the time-series charts in a deck so they compare cleanly.

Frequently asked questions
How do you change the date format on a chart’s X-axis in Ampler Charts?
Select the X-axis and use Date format in the Format menu to switch the labels to quarters, years, months, or another pattern.
Can you show a date axis as quarters?
Yes. Select the X-axis and choose a quarter format such as Q’Q from the Date format options.
Does changing the date format change the data?
No. It changes how the dates are labelled; the underlying values are untouched.
How do you reduce clutter on a long time axis?
Switch to a coarser date format — quarters or years — so the labels group the series and read without overlapping.
