This is a deprecated module that has been supplanted by change_minmax

General Module Function

The set_minmax module extends the capabilities of the clamp module by allowing setting of max values above the true maximum data range and min values below the true minimum data range. This functionality is commonly needed for color mapping of time-series data. For example, the user can set the minmax values to bracket the widest range achieved for many datasets thus allowing consistent mapping from dataset to dataset during a time-series animation. This way 100 ppm would always be red throughout the animation, and if one dataset did not reach a maximum of 100 ppm, there would be no red color mapping for those time-steps.

Module Input Ports

Set_minmax has only one input port. Input piped to this port must contain nodal data. If mesh data is piped to this port it will pass through set_minmax unchanged. The nodal data components can be scalar or vector.

Module Output Ports

Set_minmax has two output ports. The first output port (closest to the left) outputs a new nodal data set containing only the selected data component subjected to the set_minmax criteria. If a mesh is passed to the set_minmax input it will pass to the output port unchanged. The second port outputs a renderable geometry if a mesh is present.

Module Control Panel

The control panel for set_minmax is shown in the figure above. The Min Value edit field determines the minimum set value and the Max Value edit field determines the maximum set value. The data range passed from this module will match the values in these type-in boxes. Note the min and max values may be higher (and/or lower) than the current data range.
