Create a Ternary Area Diagram online with InstaNANO
The InstaNANO Graph Plotter can create a ternary area diagram directly in your browser. The interactive graph above is already initialized with example data. Replace those values with your own table, assign the supported column roles, adjust the graph settings, and inspect the result on the same page.
A ternary area diagram fills the polygon traced by three-component observations. Use it only when the ordered points describe a meaningful boundary or region in a common composition space.
Required data columns and series controls
| Column role | Supported layout | How InstaNANO uses it |
|---|---|---|
| X-axis | Numeric first component | The first composition coordinate. |
| Y-axis | Numeric second component | The second component and source of the series Color and Name. |
| Z-axis | Numeric third component | The third composition coordinate. |
The Y-axis Color and Name rows control the point, line, or area series. X-axis and Z-axis columns do not expose Color or Name cells. The current renderer normalizes the three coordinate values for positioning; it does not verify mass balance or chemical feasibility.
How to make this graph
- Start with the working example. Review the graph and table loaded above so the relationship between the columns and plotted marks is visible before you replace the values.
- Enter or paste your data. Keep the columns in the supported order shown in the table below the graph. Use the Axis row to assign each column’s role.
- Name and distinguish the series. Where the current graph supports them, use the Name row for the displayed series label and the Color row for its color.
- Check the scientific context. Add meaningful axis titles and units, review scale choices, and confirm that row order, missing values, uncertainty columns, or normalization match the intended interpretation.
- Refine and export. Use the available graph controls described below. When the figure is ready, sign in to export a PNG with Download Graph or preserve an editable

What the loaded example demonstrates
The loaded table supplies three composition columns along a “Composition Path”. It demonstrates ternary coordinate input, not a verified phase equilibrium or a composition closure check.
What InstaNANO calculates and renders
The renderer normalizes the three component values for triangular positioning and fills the polygon through the points in their supplied row order. It does not calculate a convex hull or close a scientifically derived phase boundary.
The ternary grid is drawn with the filled series; component values are normalized for display but not scientifically validated.
Scientific instruments and research data suited to this graph
Use it for a deliberately ordered composition envelope, design region, or path-derived area after the region definition has been established outside the plotting tool.
Broad instrument and data coverage
- Alloys, ceramics, and inorganic materials: Three-component alloy, oxide, ceramic, glass, cement, mineral, and phase-related compositions expressed on one verified basis.
- Batteries, electrolytes, and energy materials: Ternary active-material, solvent, salt, additive, electrode, or electrolyte formulations linked to measured or modeled behavior.
- Polymers, composites, and formulations: Polymer–filler–additive, resin–hardener–modifier, solvent-mixture, ink, coating, pharmaceutical, food, and other three-part formulation systems.
- Catalysis, chemistry, and separations: Catalyst composition, reactant or solvent mixtures, extraction systems, reaction formulations, and three-component chemical design spaces.
- Geological, environmental, and computational compositions: Soil, sediment, mineral, ecological, phase-diagram, thermodynamic, and simulation-derived three-component data after closure and basis checks.
Representative questions for this exact graph
- A deliberately defined formulation window in three-component space.
- A sampled design region whose ordered boundary is known outside the plotting tool.
- A composition envelope where filling the interior has a defensible experimental meaning.
This coverage is not limited to the instruments named above. InstaNANO can plot other experimental, microscopy-derived, computational, simulation, and processed research data when the required column roles are present and this graph’s encoding is scientifically appropriate.
Data checks before interpretation
- Express all three components on one comparable basis and check compositional closure before plotting.
- Confirm that line or polygon order represents a real path or boundary rather than an arbitrary row sequence.
Frequently asked questions about Ternary Area Diagram
Does the filled polygon calculate a valid phase or formulation region?
Polygon filling can strongly imply a continuous or valid region between points. The graph does not test closure, self-intersection, phase stability, or whether the boundary has enough sampling support.
Can I plot data from instruments or research workflows not listed here?
Yes. The instrument and dataset examples on this page are representative rather than a fixed compatibility list. InstaNANO can create a ternary area diagram from other experimental, computational, simulation, and processed research data when the table follows these roles: X-axis (numeric first component), Y-axis (numeric second component), Z-axis (numeric third component). Microscopy use refers to numeric profiles, coordinates, dimensions, counts, intensities, distributions, or map values extracted from images; the graph does not convert a raw micrograph into numerical data.
Can I use this ternary area diagram in a publication, thesis, report, poster, or presentation?
Yes, after scientific and visual review. InstaNANO can be used to prepare a ternary area diagram for a journal manuscript, thesis or dissertation, technical report, poster, conference slide, classroom presentation, or other formal scientific communication. After sign-in, Download Graph exports a PNG, defaults to 600 dpi, and offers a transparent-background option. For this graph, state the component basis, verify closure, label all three axes, and explain whether points, paths, or filled regions have a physical interpretation. Also check final dimensions, font size, line and symbol weight, color accessibility, caption content, and the destination’s required file format. The current export is PNG, so a journal that requires TIFF, EPS, PDF, SVG, or another format needs a journal-specific workflow. InstaNANO supports figure preparation, but it cannot guarantee that a journal, conference, institution, or publisher will accept a figure.
Choose a related graph when needed
Choose Ternary Line for a visible ordered path, or Ternary Diagram for independent composition observations without a defined enclosing region.
