The "step chart" is a common variation of the line chart that we currently do not offer in LO Calc. For example, in quality management the p-control chart draws the control limits using step lines (see attached example). There are many other data visualization cases (in academia as well as in companies) where the step chart is useful. For comparison, MS Excel still does not offer this chart by default, and it is very hacky to get a step chart in Excel. See for instance: https://trumpexcel.com/step-chart-in-excel/ However, I could not make the same hack work in LibreOffice. Given the usefulness of this chart, we should offer it as a variation of the "Line chart" in the chart wizard. As for customization options for this chart, I suggest using PyPlot's "step" chart as inspiration. https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.step.html
