Function plotter: Plot up to three mathematical functions with adjustable axes, zoom controls and accessible sample values.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine a number machine: put a measurement or question in one side and it follows a fixed rule to make the answer. Plot up to three mathematical functions with adjustable axes, zoom controls and accessible sample values.
Age 15Explain it to a 15-year-oldConnect it to the formula
Plot up to three mathematical functions with adjustable axes, zoom controls and accessible sample values. Each expression is parsed and sampled locally across the selected x-range. The SVG graph breaks at undefined points and large discontinuities rather than connecting them with misleading lines. Change one input or choice at a time and compare the result to see which part of the rule it controls.

The browser evaluates the selected numerical expression, conversion, or plotted function locally. Each expression is parsed and sampled locally across the selected x-range. The SVG graph breaks at undefined points and large discontinuities rather than connecting them with misleading lines. Entries and results remain in this browser. Important results should still be checked against the records, standards, or rules that govern the real situation.

Frequently asked questions
What does the Function plotter do?
Plot up to three mathematical functions with adjustable axes, zoom controls and accessible sample values.
How does the Function plotter work?
Each expression is parsed and sampled locally across the selected x-range. The SVG graph breaks at undefined points and large discontinuities rather than connecting them with misleading lines.
What can I learn from the Function plotter?
It shows how the entered values or choices produce the result. Change one input at a time to compare outcomes and understand the underlying rule.
Does MW SysArc receive or store what I enter?
No. The calculation runs locally in your browser. MW SysArc does not receive or store your calculation inputs.
How should I use the result?
Use the result as a practical reference. Review the inputs, assumptions and stated limitations before relying on it.
