Creating a Chart

Charts are created as a custom post type in the WordPress admin. Navigate to M Chart → Add New to create one.

The Spreadsheet Interface

Data is entered in a spreadsheet-style editor. You can type values directly into cells or import a CSV file.

Multi-Series Charts (Line, Spline, Area, Column, Bar)

For charts with multiple data series, organize your data so that:

• The top-left cell is empty
• Column headers (row 1, starting at column 2) are the x-axis labels
• Row headers (column 1, starting at row 2) become the series names shown in the legend
• Data values fill the remaining cells

Example:

Single-Series Charts (Pie, Doughnut, Polar)

For single-series charts, the top-left cell contains the first label — there is no empty corner cell:

• Column 1 contains the category labels
• Column 2 contains the values

Example:

Chart Settings

Below the spreadsheet and directly below the live preview you'll find the chart settings.

You'll find settings for:

• Chart Type — Select from all supported chart types
• Parse data in — Whether to parse data by rows or columns (default: rows)
• Theme — Visual color theme
• Legend — Show or hide the chart legend
• Shared Tooltip — Show all series values in a single tooltip (line/area/spline/radar only)
• X Axis Title / Y Axis Title — Optional axis labels
• X Axis Units / Y Axis Units — Optional unit labels appended to axis titles (also populates a taxonomy)
• Force vertical axis minimum — Locks the y-axis minimum to 0

Embedding

Each chart has an auto-generated shortcode shown at the bottom of the Chart Settings that can be copied and pasted into your posts. See Shortcode for embedding options. You can alternately use the M Chart block in the WordPress block editor.
