### Spectrum & Chromatogram

#### Generating a Chromatogram for an m/z Range in a Spectrum

A mass chromatogram (MC) or base peak chromatogram (BPC) can be generated for an m/z range in a spectrum.

1. Right-click at one end of an m/z range in a spectrum and drag to the other end.

   Note:

   - The mouse pointer appears as .

   - Click in the plot area as shown below.

   The context menu appears.

2. Select [Generate Chromatogram].

   The Generate Chromatogram dialog appears.

3. Select [MC], [BPC], or [Processed MC] and click [OK]. ([MC] is generating mass chromatogram from raw data and [Processed MC] is from manipurated spectra.)

   - Adjust the m/z range if necessary.

- If you select the Stacked display mode, you can display the chromatograms of multiple m/z ranges of a spectrum.
