Google sheets: chart with steps of constant height change, variable width

I want to draw a chart in Google Sheets to represent the position of a stepper motor. As the motor speeds up, it steps more quickly. But in this case, it can only ever move one step at a time. So if I want to draw a graph of its position, when it's accelerating, the chart would look like a staircase, where each step is of the same height, but the distance between steps decreases (so the staircase gets steeper as it climbs.

I've come close to doing this: Except the steps shown are not what I want; they are of constant width and varying height. I need the reverse. The data points I provided don't lend themselves to the graph I want; they just demonstrate the kind of curve I want.

How might I tabulate data and create a chart to give the kind of steps I need? For example, I might have a column which contains individual step widths, and another with step height (which would always be 1.) But then how to make that into a chart?

Stepped area chart does not support variable width of steps. But you can use the ordinary area chart like this: The data provided to this chart was as follows. The first column was marked for "use as labels" when inserting the chart.

The idea is that each x value is repeated twice, and each y value is repeated twice, but they are half-step out of sync with each other. So every time we move down the rows, exactly one of two coordinates changes: x (horizontal segment) or y (vertical segment).

For the record, the formulas were =sqrt(floor(row()/2)) and =floor((row()-1)/2) and the chart options were
