Use flags to select single points or parts of a curve. For example, to select curve points with flags, to replace the selected points with NoValues, and to then set a point with a flag, complete the following steps:

  1. Select DIAdem VIEW.

  2. Select File»New.

  3. Select one or more channels in the Data Portal.

  4. Drag and drop the selected channels into the DIAdem workspace.

  5. Select 2D Axis System.

Note If you select only one channel in the Data Portal, DIAdem displays this channel with the channel index. If you select several channels, the channel selected first is the x-channel. If you select waveform channels, DIAdem displays the waveform channels with their x-parts.
  1. Select Band Cursor.

  2. Move the band cursor to anywhere on the curve.

  3. Idle the mouse over one of the band cursor lines. The cursor changes into a double arrow. Press the mouse button and specify the width of the band cursor.

  4. Click Set Flags. DIAdem selects the curve area within the band cursor.

  5. Click Flags: Remove Points to replace the values in the selected curve section with NoValues.

Note  Select Settings»DIAdem Settings»VIEW to specify whether DIAdem deletes the points that it removes or whether DIAdem replaces these points with NoValues.
  1. Select the Crosshair Cursor.

  2. Position the crosshair cursor at the first point you want to interpolate the deleted section with.

  3. Select Set Data Point and Flag in the 2D axis system. DIAdem creates the first data point at the point you selected with the crosshair cursor.

  4. Position the crosshair cursor at the second point you want to interpolate the deleted section with.

  5. Select Set Data Point and Flag in the 2D axis system. DIAdem creates the second data point at the point you selected with the crosshair cursor.

  6. Click Flags: Interpolate NoValues to interpolate the curve area. DIAdem interpolates the curve with the two specified points.

  7. Select Flags»Delete (All Curves) in the context menu to remove the selection from the curve.
