Andy,
<div class=""><br class="">
</div>
<div class="">I combined the Extract Filter Block with the example you outlined below and it worked! I was able to use GetRange() to get the minimum and maximum of the array for the current time. </div>
<div class=""><br class="">
</div>
<div class="">On a side note, other than GetRange(), what else can be done with data from GetArray()?</div>
<div class=""><br class="">
</div>
<div class="">Best, Ryan </div>

<div class="">Hi,<br class="">
<br class="">
Besides Yoshimi's way, you should be able to do something like the following from pvpython, pvbatch or Python shell.<br class="">
<span style="font-family: courier; font-size: 7.8pt;" class="">yourfilter.PointData.GetArray(<arrayname>).GetRange() # or CellData<br class="">
<br class="">
</span></div>
<div class=""><span style="font-family: courier; font-size: 7.8pt;" class="">For example, for a Python script for a Wavelet source you would do the following:<br class="">
</span></div>
<div class=""><span style="font-family: courier; font-size: 7.8pt;" class="">w = Wavelet()<br class="">
</span></div>
<div class=""><span style="font-family: courier; font-size: 7.8pt;" class="">w.UpdatePipeline() # needed to execute the pipeline to create the output<br class="">
</span></div>
<div class=""><span style="font-family: courier; font-size: 7.8pt;" class="">w.PointData.GetArray("RTData").GetRange()<br class="">
</span></div>
<div class=""><span style="font-family: courier; font-size: 7.8pt;" class=""><br class="">
</span></div>
<span style="font-family: courier; font-size: 7.8pt;" class="">This will work for the output of a filter that returns a regular VTK data set or a multiblock data set. If you want the range for only a single block of a multiblock I'd recommend using the Extract
Block filter to get that block. It should be a shallow copy of the data set to do that so it should be very fast, even if you don't need the output of the Extract Block filter for anything else.<br class="">

Hi,<br class="">
<br class="">
I also want to know if there is a simple way to do, since I only have<br class="">
the somewhat redundant code:<br class="">
---<br class="">
source = GetActiveSource()<br class="">
<br class="">
#options for component: -1, 0, 1 and 2 => Mag, X, Y, Z<br class="">
component = -1<br class="">
<br class="">
cdi = source.GetDataInformation().<wbr class="">GetCompositeDataInformation()<br class="">
<br class="">
for i in range(cdi.GetNumberOfChildren(<wbr class="">)):<br class="">
print 'Block Name: ', cdi.GetName(i)<br class="">
<br class="">
data = cdi.GetDataInformation(i).<wbr class="">GetCellDataInformation()<br class="">
for j in range(data.GetNumberOfArrays()<wbr class="">):<br class="">
array = data.GetArrayInformation(j)<br class="">
arrayName = array.GetName()<br class="">
dataRange = array.GetComponentRange(<wbr class="">component)<br class="">
print arrayName, dataRange<br class="">
---<br class="">
<br class="">
Thanks,<br class="">
yoshimi<br class="">
