ymax2

ymax2 is a variable label used in data analysis, computer graphics, and mathematical modeling. It commonly denotes the maximum value of a second set of y-values or the upper bound associated with a second y-axis or data series. The exact meaning depends on context, but the general idea is to provide a scalar ceiling for y2 or for a second dimension of a plot or model.

In plotting, ymax2 is used in dual-axis charts to scale the secondary y-axis so that the second dataset fits within the plotting area. It is typically computed as the maximum of the corresponding y2 data, after handling missing values. The value may be used as an explicit axis limit or passed to a plotting function to set the upper bound.

In data processing and programming, ymax2 can be a field in a data structure or a local variable in a script, assigned as max(y2). When datasets are merged or compared, ymax2 may vary between runs and is used to adjust normalization, formatting, or visualization.

In optimization or mathematical modeling, ymax2 may denote an upper bound on the second decision variable y in a constraint or scenario, such as y ≤ ymax2 in a given formulation.

Naming conventions vary; some codebases use ymax2 alongside ymax1 or y_max, while others use second_y_max or axis2_max. The suffix indicating "2" commonly signals a second axis, scenario, or dataset.
