Numbers Are Not Always Enough

A solved equation gives you a value. A graph gives you behavior — where a function turns over, where two curves intersect, what happens as a parameter slides toward an edge case. For anyone designing, modeling, or analyzing, those visual cues are often the actual deliverable.

Most tools force a detour to get them. You open a separate plotter, configure axes, export an image, paste it back in, then redo the loop the next time a number changes. The plot ends up frozen in the report, disconnected from the math that produced it.

GridDoc keeps the plot connected. Graph is a first-class action on any equation in your document, and the result lives on the same canvas as everything else.

Graphing Without Leaving the Canvas

Once an equation has been recognized on the canvas — typed, written with Draw to Solve, or returned by one of the built-in solvers — it shows up as a graphable expression. Select it, hit Graph, and GridDoc renders the curve as a regular block. No separate window, no export step, no second tool.

Because the plot is a block, it follows the same rules as every other block. Resize it, drag it next to the equation it represents, position it inside a Book View page for export, or tuck it into the corner of a calculation panel where it won't crowd the prose. The Ribbon Toolbar exposes the same controls you already use for tables and text.

Multiple Equations, One Set of Axes

The feature most engineers actually need shows up under Graph Together. Select more than one equation and GridDoc plots all of them on a shared coordinate system, with each curve labeled so you can tell them apart. That is what makes graphing useful for real work — comparing a measured response to a predicted one, layering a quadratic fit over a linear baseline, or seeing where two design curves cross.

Equations the engine cannot plot are surfaced clearly rather than silently dropped. If you select an expression that resolves to a constant or contains a symbol the plotter doesn't yet handle, you'll see the Cannot graph this expression flag instead of an empty plot. The same is true if no graphable equation is selected — GridDoc tells you, instead of guessing.

Graphs That Recalculate

The reason the plot stays useful weeks later is the same reason GridDoc's tables and formulas stay useful: it isn't a static image. The graph is bound to the equation, and the equation is bound to the values it depends on.

Change a coefficient in a nearby table. The equation re-evaluates. The plot redraws. Cross-block references — the same mechanism that keeps a SUM tied to its source rows — keep the curve tied to its source variables. There is no "rebuild plot" step to forget.

For engineers writing reports that get reviewed, revised, and reused, this is the part that matters. A graph in a Word document drifts out of date the moment a single input changes. A graph in GridDoc moves with the math.

Where It Fits With the Rest of GridDoc

Graphing slots in next to the features it should have shipped with:

• Solvers. Run a Quadratic Solver or System Solver to find the answer, then plot the underlying expressions to show that answer in context.
• Draw to Solve. Sketch an equation by hand, watch GridDoc work it out step by step, and graph the same expression in the block beside it.
• Cross-block references. Curves redraw when their source values move, the same way a downstream formula does.
• Book View. When you switch from the spatial canvas to a paginated layout, graph blocks paginate cleanly with the rest of your content.

Solving tells the reader what the value is. Graphing tells them what the function does. Putting both on the same canvas — beside the inputs, the steps, and the prose — is the part GridDoc was built for.
