If the Edit Color Map button is clicked in the Display tab in ParaView, the Color Scale Editor pop-up window will appear. This window has two tabs: Color Scale and Color Legend. The first tab of the Edit Color Map window allows the user to choose from several default color maps, to allow the user to import or export their own color map, or to allow the user to create their own color maps. At the top of the Color Scale Editor window is the color map editor. This editor displays the mapping from the scalar values to color. It also allows the user to make changes to this mapping. Colors are mapping linearly between the colored spheres, or nodes. The user can add more nodes by left-clicking with the mouse. The selected node is slightly larger than a non-selected node. To delete a node, first select it and then press the d or delete key. The ParaView Color Selector will open if the user left-clicks on a selected node. This will allow the user to change the color of the node by selecting a color from one of the Basic colors, or create one of their own custom colors using the color selector, HSV editor, or RGB editor. The scalar value for a selected node can be changed by dragging the node either to the left (decreasing scalar value) or to the right (increasing scalar value). Alternately, the scalar value for a selected node can be changed by entering a value into the Selected Value entry box. The color of the node will not change when the scalar value is changed. For datasets that are geometry (not volume rendered) the Opacity and Scale boxes are greyed out. To adjust the opacity of a geometric dataset, the user can adjust the Opacity spinner on the Display tab under the Object Inspector. For volume rendered datasets, the Opacity and Scale boxes will be visible. The Color Legend panel allows the user to show the Color Legend bar in the ParaView display window, to change its labeling, font style, and number format. The Labels section uses syntax similar to C’s printf. The default setting of ‘%-#6.3g’ can be read as the following: The Number of Labels changes the number of labels on the scalar color bar. By default, there are five labels. WARNING!! This Department of Defense interest computer system is subject to monitoring at all times.
