setWidths(containerName, widths) specifies possible widths that an slmetric.dashboard.Container object can have. You can specify up to four different widths. For the input argument widths, pass either one value or an array of four values. You can choose from these possible values:

These values correspond to the different sizes that a container can have as the screen size changes. If you specify one value, the container always has that value regardless of the screen size. If you specify four different values, the container size can change four times as you maximize and minimize the screen.
