Hello,
I've tried to use the 'timeline' chart to illustate features in a protein
sequence. The resulting image I got was very close to what I would like to
get but I need to have integers on the x-axis instead of dates.
For instance I have a protein sequence of 1019 amino acids and would like
to represent domain features on this sequence. As a domain feature, I have
e.g. SEA-PS50024 starting at position 54 and ending at position 169. I've
'tweaked' the positions (discrete positive numbers) into dates by adding a
1000 to each of them as 'date' would not allow for e.g. year 0054 (too
early?). Visually, the result I got was nearly exactly what I wanted but I
would definitely need to be able to put numbers as 'Start' and 'End' to go
forward.
The following code's extract is what I tested:
dataTable.addColumn({ type: 'string', id: 'Type' });
dataTable.addColumn({ type: 'string', id: 'Name' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([
[ 'Profile', 'SEA-PS50024', new Date(1054, 0, 1), new Date(1169,
11, 31) ],
[ 'Profile', 'LDLRA_2-PS50068', new Date(1183, 0, 1), new
Date(1222, 11, 31) ],
[ 'Profile', 'CUB-PS01180', new Date(1225, 0, 1), new Date(1334,
11, 31) ],
[ 'Profile', 'MAM_2-PS50060', new Date(1330, 0, 1), new
Date(1504, 11, 31) ],
[ 'Profile', 'CUB-PS01180', new Date(1450, 0, 1), new Date(1634,
11, 31) ],
[ 'Profile', 'LDLRA_2-PS50068', new Date(1450, 0, 1), new
Date(1678, 11, 31) ],
[ 'Profile', 'SRCR_2-PS50287', new Date(1679, 0, 1), new
Date(1788, 11, 31) ],
[ 'Profile', 'TRYPSIN_DOM-PS50240', new Date(1700, 0, 1), new
Date(2019, 11, 31) ]
And this is what I would like to be able to use instead:
dataTable.addColumn({ type: 'string', id: 'Type' });
dataTable.addColumn({ type: 'string', id: 'Name' });
dataTable.addColumn({ type: '*number*, id: 'Start' });
dataTable.addColumn({ type: '*number*', id: 'End' });
dataTable.addRows([
[ 'Profile', 'SEA-PS50024', *54, 169* ],
[ 'Profile', 'LDLRA_2-PS50068', *183, 222*],
[ 'Profile', 'CUB-PS01180', *225, 334*],
[ 'Profile', 'MAM_2-PS50060', *330, 504*],
[ 'Profile', 'CUB-PS01180', *450, 634* ],
[ 'Profile', 'LDLRA_2-PS50068', *450, 678*],
[ 'Profile', 'SRCR_2-PS50287', *679, 788*],
[ 'Profile', 'TRYPSIN_DOM-PS50240', *700, 1019*]
Thank you for your help,
Béatrice
