Charts and data

Ask for a chart and you get a native PowerPoint chart object. Click it and the ribbon’s Chart Design and Format tabs light up. Right-click a classic chart and Edit Data opens the numbers behind it. Nothing about it is an image. When someone else picks the deck up, they can change a figure, add a series, or restyle the chart without you, and without Pretty.

What it can build

Family	Types
Column and bar	Clustered, stacked, 100% stacked, 3-D
Line and area	Plain, with markers, stacked, 100% stacked, smoothed
Circular	Pie, doughnut, exploded, pie-of-pie, bar-of-pie
Numeric axes	Scatter (markers, lines, smoothed), bubble
Sequential	Waterfall, funnel
Hierarchy	Treemap, sunburst
Statistical	Histogram, Pareto, box and whisker
Other	Radar, stock, combo charts, region map

Chart chrome is available too: axis formatting, data labels, legends, titles, per-series and per-point styling, error bars and trendlines. Ask for it in words (“put data labels on the last series only”, “start the axis at 60, not zero”) rather than describing PowerPoint menus.

A region map chart shades geography by value. If you want a map you can recolour district by district as editable shapes instead, that is the Maps asset, which is a different thing.

Handing over the data

In the prompt
From a file
From a document or screenshot

Fine for anything you can type. Give the series names, the categories and the units.

Column chart of revenue by region for FY24 and FY25, in EUR millions:

EMEA      41.2   52.8
Americas  63.7   68.1
APAC      18.9   29.4

FY24 in grey, FY25 in the accent colour, data labels on FY25 only.
Title: "APAC is where the growth is."

Attach a .csv or .xlsx and name what to plot. Pretty reads the workbook, including which sheet and which columns.

From the attached actuals.xlsx, sheet "Monthly": plot net revenue by
month for 2025 as a line chart, with a second line for the same months
in 2024. Ignore the rows below the "Total" line.

Attach the file by dragging it onto the pane (it shows Drop to reference in chat) or with Upload files.

Pretty can pull figures out of a PDF’s text or read a table out of a screenshot.

Table 3 on page 11 of the attached annual report has segment revenue for
the last three years. Build a stacked column chart from it, one column
per year, one segment per series.

A scanned PDF with no text layer comes back empty, since there is no OCR. Screenshot the table instead and attach that.

Be explicit about units and scale. “Revenue 41.2” could be thousands, millions or a percentage, and a chart that silently picks the wrong one is worse than no chart. State the unit and put it in the axis title.

Prompts that produce good charts

Say what the chart has to prove, not just what to plot. The takeaway drives the chart type, the sort order and what gets emphasized.

Waterfall showing how we got from 12.4m opening ARR to 15.1m closing ARR:
new business +4.2, expansion +1.6, downgrade -1.1, churn -2.0. Positive
steps in the accent colour, negatives in red, totals in dark grey.

Scatter of our top 30 accounts, contract value on the x axis and support
tickets per month on the y. Label only the five accounts above 50 tickets.
The point is that our biggest accounts are not our noisiest ones.

100% stacked bar of headcount by function for each of the last four
quarters, so the shift towards engineering is visible. Four bars, one per
quarter, engineering at the bottom of every stack.

Restyling a chart you already have

Click the chart on the slide so it is selected, then ask. The selection badge in the composer tells Pretty which chart you mean.

Recolour this chart to the master palette, drop the gridlines and the
chart border, move the legend to the bottom, and set the axis labels in
the deck's body font at 10pt.

Same chart, but sort the categories by FY25 descending, grey out
everything except the top three, and add a dashed trendline to the
second series.

Changing the numbers works the same way. Say what changed and Pretty updates the chart’s data rather than rebuilding it from scratch:

Q4 came in at 71.3, not 68.1. Update the Americas FY25 value and leave
everything else alone.

If the chart is not right

Numbers look off. Right-click a classic chart and choose Edit Data to see exactly what it plotted. That is the source of truth, not the drawn chart.
Too busy. Ask for fewer series, a sorted order, or labels on one series only. “Remove everything that is not carrying the argument” is a valid instruction.
