How to plot Marker data in MatLab

Hi. I want to know how I can plot the marker data from an EDF file in MatLab.

So I use edfread to convert the EDF file :

[header, data] = edfread('Subject1.edf');

and then I get the below after typing in header

      ver: 0
    patientID: '1                                                                               '
     recordID: '1                                                                               '
    startdate: '11.07.16'
    starttime: '07.52.30'
        bytes: 9472
      records: 948
     duration: 1
           ns: 36
        label: {1x36 cell}
   transducer: {1x36 cell}
        units: {1x36 cell}
  physicalMin: [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
  physicalMax: [1x36 double]
   digitalMin: [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
   digitalMax: [1x36 double]
    prefilter: {1x36 cell}
      samples: [1x36 double]

the marker is in label, so I access it by typing in

header.label

which gives me the below

>> hdr.label

ans = 

    Columns 1 through 13

      'COUNTER'    'INTERPOLATED'    'AF3'    'F7'    'F3'    'FC5'    'T7'    'P7'    'O1'    'O2'    'P8'    'T8'    'FC6'

    Columns 14 through 24

      'F4'    'F8'    'AF4'    'RAW_CQ'    'CQ_AF3'    'CQ_F7'    'CQ_F3'    'CQ_FC5'    'CQ_T7'    'CQ_P7'    'CQ_O1'

    Columns 25 through 34

      'CQ_O2'    'CQ_P8'    'CQ_T8'    'CQ_FC6'    'CQ_F4'    'CQ_F8'    'CQ_AF4'    'CQ_CMS'    'CQ_DRL'    'GYROX'

    Columns 35 through 36

      'GYROY'    'MARKER'

hdr.label{end} returns the marker string, but I want to know how I can view the values of markers and possibly even plot them.

The values are strings. So what does it mean to plot strings? You can display the strings using the text() function - maybe that's what you want.

[Walter Roberson]

Perhaps you want to use them as legend entries?
