Overview

Column and bar charts are the most common chart types in business presentations. The pptx.dev API supports single series, clustered, stacked, and 100% stacked variants for both vertical (column) and horizontal (bar) orientations.

Column and Bar Chart Types

OPF type Description
column Vertical columns; several series sit side by side
stacked-column Series stacked into one column per category
100pct-stacked-column Series normalized to each category’s total
bar Horizontal bars; several series sit side by side
stacked-bar Series stacked into one bar per category
100pct-stacked-bar Horizontal series normalized to each category’s total

The data columns determine the series count. A two- or three-series chart uses the same type.

Example: Revenue by Quarter

{
  "$schema": "https://openpresentation.org/schema/opf/v1",
  "name": "Quarterly Revenue",
  "slides": [
    {
      "layout": "chart",
      "title": "Quarterly Revenue",

            "Q3",
            "Q4"
          ],
          "rows": [
            [
              "Revenue ($K)",
              320,
              480,
              540,
              620
            ]
          ]
        }
      },

      "layouts": {
        "chart": {
          "name": "Chart",

              "flow": "grid"

              "accepts": [

          }
        }
      }
    }
  }
}

Example: Year-Over-Year Comparison

Use column with two numeric data columns to compare two years:

{
  "$schema": "https://openpresentation.org/schema/opf/v1",
  "name": "Revenue: 2025 vs. 2026",
  "slides": [
    {
      "layout": "chart",
      "title": "Revenue: 2025 vs. 2026",
      "chart": {
        "type": "column",
        "data": {
          "columns": [
            "Series",
            "Q1",
            "Q2",
            "Q3",
            "Q4"
          ],
          "rows": [
            [
              "2025",
              280,
              350,
              420,
              510
            ],
            [
              "2026",
              320,
              480,
              540,
              620
            ]
          ]
        }
      },
      "design": {
        "titleAlignment": "center",
        "contentAlignment": "center"
      }
    }
  ],
  "catalogs": {
    "default": {
      "source": "https://www.pptx.gallery",
      "layouts": {
        "chart": {
          "name": "Chart",
          "summary": "One to six charts, with an optional note.",
          "tags": [
            "Visuals"
          ],
          "direction": "column",
          "regions": [
            {
              "name": "title"
            },
            {
              "name": "charts",
              "accepts": [
                "chart",
                "group"
              ],
              "role": "primary",
              "flow": "grid"
            },
            {
              "name": "note",
              "size": "auto",
              "accepts": [
                "text"
              ],
              "role": "supporting",
              "flow": "none"
            }
          ],
          "description": "Give a chart enough space to show its evidence. Use the title to state the conclusion and labels to explain the measures.",
          "preview": {
            "vectorSrc": "https://www.pptx.gallery/layout-previews/chart.svg"
          }
        }
      }
    }
  }
}

Example: Stacked Revenue Breakdown

Use stacked-column with one numeric data column per segment to show the revenue breakdown:

{
  "$schema": "https://openpresentation.org/schema/opf/v1",
  "name": "Revenue by Segment",
  "slides": [
    {
      "layout": "chart",
      "title": "Revenue by Segment",
      "chart": {
        "type": "stacked-column",
        "data": {
          "columns": [
            "Series",
            "Q1",
            "Q2",
            "Q3",
            "Q4"
          ],
          "rows": [
            [
              "Enterprise",
              180,
              220,
              260,
              300
            ],
            [
              "Mid-Market",
              100,
              160,
              180,
              200
            ],
            [
              "SMB",
              40,
              100,
              100,
              120
            ]
          ]
        }
      },
      "design": {
        "titleAlignment": "center",
        "contentAlignment": "center"
      }
    }
  ],
  "catalogs": {
    "default": {
      "source": "https://www.pptx.gallery",
      "layouts": {
        "chart": {
          "name": "Chart",
          "summary": "One to six charts, with an optional note.",
          "tags": [
            "Visuals"
          ],
          "direction": "column",
          "regions": [
            {
              "name": "title"
            },
            {
              "name": "charts",
              "accepts": [
                "chart",
                "group"
              ],
              "role": "primary",
              "flow": "grid"
            },
            {
              "name": "note",
              "size": "auto",
              "accepts": [
                "text"
              ],
              "role": "supporting",
              "flow": "none"
            }
          ],
          "description": "Give a chart enough space to show its evidence. Use the title to state the conclusion and labels to explain the measures.",
          "preview": {
            "vectorSrc": "https://www.pptx.gallery/layout-previews/chart.svg"
          }
        }
      }
    }
  }
}

Example: Horizontal Bar Chart

Horizontal bars work better when category labels are long:

{
  "$schema": "https://openpresentation.org/schema/opf/v1",
  "name": "Customer Satisfaction by Department",
  "slides": [
    {
      "layout": "chart-beside",
      "title": "Customer Satisfaction by Department",
      "chart": {
        "type": "bar",
        "data": {
          "columns": [
            "Series",
            "Engineering",
            "Customer Success",
            "Sales",
            "Marketing",
            "Operations"
          ],
          "rows": [
            [
              "CSAT Score",
              92,
              88,
              85,
              82,
              79
            ]
          ]
        }
      },
      "design": {
        "contentAlignment": "center"
      }
    }
  ],
  "catalogs": {
    "default": {
      "source": "https://www.pptx.gallery",
      "layouts": {
        "chart-beside": {
          "name": "Chart beside",
          "summary": "A chart with the takeaway beside it.",
          "tags": [
            "Visuals"
          ],
          "direction": "column",
          "regions": [
            {
              "name": "title"
            },
            {
              "direction": "row",
              "regions": [
                {
                  "name": "chart",
                  "size": 3,
                  "accepts": [
                    "chart"
                  ],
                  "role": "primary",
                  "flow": "none"
                },
                {
                  "name": "notes",
                  "size": 2,
                  "accepts": [
                    "text",
                    "list",
                    "metric",
                    "quote",
                    "chart"
                  ],
                  "role": "supporting",
                  "flow": "column"
                }
              ]
            }
          ],
          "description": "Pair a chart with an explanation of its result. Keep the text focused on the pattern or decision supported by the data.",
          "preview": {
            "vectorSrc": "https://www.pptx.gallery/layout-previews/chart-beside.svg"
          }
        }
      }
    }
  }
}

When to Use Each Type

Use case Chart type
Single metric over time column
Comparing two groups column or bar with several series
Part-to-whole over time stacked-column
Percentage composition 100pct-stacked-column
Long category labels bar
