Create native PowerPoint charts with Deckary

Create editable PowerPoint charts with embedded workbook data, consulting display controls, and optional links to Excel ranges.

Last verified: 2026-09-04

Deckary creates bar, 100% stacked bar, waterfall, line, scatter, and pie charts as native PowerPoint charts with embedded Excel workbook data. These charts remain editable in PowerPoint. Gantt charts use grouped PowerPoint shapes because their activity and timescale layout differs from a standard Office chart.

Insert a chart#

Open Deckary's Charts pane, choose a chart family, then provide data manually or select an available Excel link. Deckary validates the data and chart configuration before inserting the chart on the active slide.

Native charts can use titles, legends, data labels, number formats, category ordering, and palette controls. Some consulting treatments that Office does not represent directly—such as delta brackets or waterfall connectors—are stored as chart overlay shapes while the main chart remains native.

Edit an existing Deckary chart#

Select the chart to load its current Deckary configuration. Changes preserve the chart's logical identity and the position or size adjustments you made in PowerPoint. Deckary replaces the internal chart package parts as one transaction and verifies that PowerPoint reimported the expected chart before reporting success.

Copied charts are handled separately. When two shapes initially share the same Deckary identity, the add-in assigns the copy a new chart and instance identity before either one is edited.

Use charts with the AI slide builder#

The PowerPoint AI agent can create and edit the supported native chart families inside its normal slide-authoring workflow. Gantt remains a manual chart workflow and is not exposed through the agent's chart-editing helper. For the broader slide process, see Build and edit PowerPoint slides with AI.
