MinMax

The MinMax modules calculates the minimum and maximum value of a scalar data set. It outputs either a min-max pair that can be used for example as input for a colormap module, or a list of x-y pairs that shows the distribution of values over the range.

MinMax is available for COVISE version 3.1 and higher. It's tested on SGI systems (IRIX 6.2,6.3,6.4,6.5) and HP systems (HP-UX10.20).

Parameters

Name	Type	Description
NumBuck	Slider	number of steps for distribution of values

Input Ports

Name	Type	Description
requiredData	Float Float	scalar input field

Output Ports

Name	Type	Description
output2dplot	Unstructured_2D_Data	2D array with a list of values (the step size depends on the NumBuck Parameter) and a list with the number of data points that are in the corresponding interval
outputminmax	MinMax_Data	Minimum and maximum value for usage in ColorMap module

Examples

Figure: covise/net/general/examples/MinMax.net

In this example the MinMax module is used to set the colormap for Colors module. Thus the color of the resulting isosurface is chosen according to the value in relation to the min and max value of the whole data set. If the MinMax module were not used, the color would always be the same, independent from the current iso value.

In the plot window the distribution of the data values over the whole range can be seen. The NumBuck value is 50, so 50 different bars will be displayed.
