MinimumValue Property (VoxelVariableStatistics)
Gets the minimum value of the data.

Public ReadOnly Property MinimumValue As Double
Access Stats and Color Range for a Stretch Renderer
//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()
//Get the variable profile on which to access the data
var variable = voxelLayer.SelectedVariableProfile;
//or use ...voxelLayer.GetVariableProfiles()
//Data range
//At 2.x -
//var min = variable.GetVariableStatistics().MinimumValue;
//var max = variable.GetVariableStatistics().MaximumValue;
var min = variable.Statistics.MinimumValue;
var max = variable.Statistics.MaximumValue;
//Color range (Continuous only)

Change Stretch Renderer Color Range
//Typically, the default color range covers the most
//commonly occuring voxel values. Usually, the data
//range is much broader than the color range
//Get the variable profile whose renderer will be changed
var variable = voxelLayer.SelectedVariableProfile;
//Check DataType
if (variable.DataType != VoxelVariableDataType.Continuous)
return;//must be continuous to have a Stretch Renderer...
var renderer = variable.Renderer as CIMVoxelStretchRenderer;
var color_min = renderer.ColorRangeMin;
var color_max = renderer.ColorRangeMax;
//increase range by 10% of the current difference
var dif = (color_max - color_min) * 0.05;
color_min -= dif;
color_max += dif;
//make sure we do not exceed data range
//At 2.x -
//if (color_min < variable.GetVariableStatistics().MinimumValue)
// color_min = variable.GetVariableStatistics().MinimumValue;
//if (color_max > variable.GetVariableStatistics().MaximumValue)
// color_max = variable.GetVariableStatistics().MaximumValue;
if (color_min < variable.Statistics.MinimumValue)
