I wanted to create a contour plot with the gray scale from white (lowest value) to black (highest value) in paraview.
The default gray scale is opposite to what I want.
How can I make a contour plot with white to black?
Thanks in advance for your help.

Greetings Jeong,

Simple:

1. You export the gray one to an XML file.
2. Switch the values for "x" in the saved file.
3. Import the modified file.

Here's the modified file contents:

<ColorMap name="Grayscale" space="RGB">
  <Point x="0" o="1" r="1" g="1" b="1"/>
  <Point x="1" o="0" r="0" g="0" b="0"/>
  <NaN r="1" g="0" b="0"/>
</ColorMap>

I also swapped the lines of the two "Point" elements.
You can also change the "name" of the "ColorMap".

Best regards,
Bruno

OK, so somebody who I won't mention, has asked me for more details on this topic.
So here goes a quick step-by-step guide:

1. Start ParaView.
2. Load your data file(s).
3. Turn on the data set you want to represent. Example, see first attached image.
4. Click on the "Edit Color Map" button, shown in the second image.
5. Click on the "Choose Preset" button, shown in the third image.
6. As shown in the fourth image, you can either choose one of the presets or click on the "Import" button to load a manually created file.
   • The example for a manually created one is documented in post #2: http://www.cfd-online.com/Forums/ope...tml#post375397
7. Once the preset is chosen, by clicking on it, then click on the OK button and you're good to go!

Best regards,
Bruno
