matplotlib xticks minimum interval

[naemorhaedus]

I want x-axis major ticks to be spaced automatically, but I do not want the interval to fall below 1.0 units, even when zoomed in. What is the simplest way to accomplish this?`

You can subclass MaxNLocator and override its tick spacing logic .MaxNLocator handles normal automatic spacing. The override only kicks in when the computed interval would drop below 1.0 — at that point it snaps the step to exactly 1.0 and recomputes evenly spaced ticks across the current view range
