Create a Multi-Y Line Chart online with InstaNANO
The InstaNANO Graph Plotter can create a multi-y line chart 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 multi-Y line chart plots several Y series against one numeric X coordinate while giving each series its own vertical scale. Use it when the series have different units or substantially different magnitudes.
Required data columns and series controls
| Column role | Supported layout | How InstaNANO uses it |
|---|---|---|
| X-axis | One numeric coordinate column | The shared horizontal coordinate for every enabled Y-axis series. |
| Y-axis | One or more numeric series columns | Each enabled Y-axis column becomes a separate series paired with the preceding X-axis column. |
For each Y-axis column, the Color row controls the series color and the Name row provides the displayed series label. X-axis columns do not expose Color or Name cells in the current table.
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 contains a shared X-axis with the two illustrative series “Low-Scale Signal” and “High-Scale Signal”. It demonstrates the required column arrangement, not a validated experimental result.
What InstaNANO calculates and renders
The renderer creates one colored line per Y-axis column and initializes separate Y scales for the series. It preserves the shared X coordinate while avoiding compression of a smaller-magnitude series.
The Multi Y Scales control is initialized for this preset, together with standard Cartesian axis and series controls.
Scientific instruments and research data suited to this graph
Use it to inspect synchronized measurements such as temperature and current, or signals recorded on very different numerical ranges, while retaining a common experimental sequence.
Broad instrument and data coverage
- Multi-technique experiments: Synchronized optical, thermal, electrical, electrochemical, mechanical, or environmental signals collected during one experiment but expressed in different units or ranges.
- Spectroscopy and diffraction series: XRD, Raman, FTIR, UV–visible, photoluminescence, XPS, NMR, EELS, or EDS profiles that require separate X domains, separate Y scales, or both.
- Microscopy-derived and metrology profiles: AFM or profilometer line scans, SEM/TEM/STEM intensity profiles, particle trajectories, and elemental line scans recorded over different distances or with different response units.
- Thermal and coupled-property measurements: TGA/DTG, DSC/DTA, DMA, temperature, mass, heat-flow, dimensional-change, and conductivity channels compared across a shared or separate experimental coordinate.
- Process, sensor, and computational data: Multi-sensor time series, reactor variables, environmental monitoring channels, multiphysics outputs, and simulation curves whose coordinate domains should not be forced onto one scale.
Representative questions for this exact graph
- Temperature and electrical current recorded at the same time points but in different units.
- Absorbance and pH measured through one reaction sequence.
- Stress, acoustic response, or displacement series sharing an experimental coordinate but not a common Y scale.
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
- Confirm that X and every enabled Y column are numeric and carry the intended units.
- Arrange rows in the scientifically meaningful sequence: sort by X for a single-valued profile, but preserve acquisition order for cycles, hysteresis, and trajectories.
Frequently asked questions about Multi-Y Line Chart
Can equal screen heights be compared across the separate Y scales?
Separate Y scales make curve shapes easy to compare but can make equal screen heights look numerically comparable when they are not. Keep the units and scale limits explicit.
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 multi-y line chart from other experimental, computational, simulation, and processed research data when the table follows these roles: X-axis (one numeric coordinate column), Y-axis (one or more numeric series columns). 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 multi-y line chart in a publication, thesis, report, poster, or presentation?
Yes, after scientific and visual review. InstaNANO can be used to prepare a multi-y line chart 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, verify the X order, axis units, scale choice, series labels, and whether any connecting line or filled baseline is scientifically justified. 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 Line Chart when absolute Y values must share one scale, or Line Multi-X + Multi-Y when each measurement also needs a different horizontal coordinate.
