Draw a selection box around the points you want in the group. Position the mouse pointer on any one of them and drag it to the desired location. All of the control points move together within the constraints of the unselected points above and below. By constraining horizontally after adding a precise control point, you can move the point to change the color or opacity mapped to specific value, without changing the value itself. Creating Waveforms To create waveforms, select the Generate Waveforms option from the Edit pull-down menu.
Waveforms can be step, square, or sawtooth.
Choose the range of the waveform from an options box. Specify the number of steps to be created in the range of the waveform by using the stepper. The number of steps specified can be between 2 and 100. Copying and Pasting Control Points Control points can be copied and pasted from one Colormap area to another, using the Copy and Paste options of the Edit window. Select the control point or control points you wish to copy.
