Recipe 2 — Axis Ranges and Grid Spacing

Axis ranges can be configured three ways: bounds only with derived divisions, bounds with a specified division count, or bounds with explicit minor and major step sizes. This recipe compares the three forms so you can choose between letting ViewPoint pick readable spacing, requesting a fixed number of divisions, or matching a domain-specific grid exactly. See Axis Configuration.

Recipe 2 — three range overloads compared on stacked plots

#include <ViewPoint.h>

void setup() {
    view.begin();
    view.setNumberOfPlots(3);

    view.plot(0).setTitle("min, max");
    view.plot(0).setVerticalRange(-1.0, 1.0);

    view.plot(1).setTitle("min, max, divisions");
    view.plot(1).setVerticalRange(-1.0, 1.0, 8);

    view.plot(2).setTitle("min, max, minor, major");
    view.plot(2).setVerticalRange(-1.0, 1.0, 0.1, 0.5);
}

void loop() {
    view.send();
}

What the functions do

• setVerticalRange(min, max) sets bounds only; ViewPoint chooses readable grid spacing.
• setVerticalRange(min, max, divisions) splits the axis into a fixed number of equal segments.
• setVerticalRange(min, max, minor, major) sets explicit small and large grid spacing in data units.
• setTitle(...) — per-plot titles appear in the Controls panel.
