Use flags to select single points or parts of a curve. To select a curve with flags, to replace the selected points with NoValues, and to then interpolate the area, complete the following steps:

  1. Select the DIAdem VIEW panel.

  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. To interpolate curve values you first must replace the values with NoValues. Select Settings»DIAdem Settings»VIEW and specify that DIAdem replaces points with Novalues.

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

  6. Click Flags: Remove Data Points to remove the selected curve area and to replace the values with NoValues.

  7. Click Flags: Interpolate NoValues to interpolate the curve area. DIAdem draws the interpolated curve area into the curve.

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