change the range of the colorbar

[valentinamun]

Hello Team,

¿How can i change the range of the colorbar between -200 and 0 in the graphic?

Hi, you should use vmin and vmax, not zmin and zmax (same as standard matplotlib)

[valentinamun]

Thanks, but I still have problems with the colorbar range using the vmin and vmax. my script are not working.

#!/usr/bin/

import os
import opendrift
import numpy as np
import os.path
from datetime import datetime, timedelta

o = opendrift.open("mosa_VM_1mes_horario_back_AS_27-31Enero.nc",elements=np.arange(0,587160,500))
o.plot(buffer=.2, vmin=-200, vmax=0, linecolor = 'z', fast=True, filename='prueba.png')

Valentina, try cmin and cmax, instead of zmin zmax

[knutfrode]

Hm, it is supposed to be vmin and vmax.
Are you sure the particles really span depths from -200 to 0?

Hi Knut,

It is a backwards simulation. The release points are between 0 and 200m, that is why we want to restrict the colorbar to -200m to 0m.

[knutfrode]

Ok. You can also check the actual depths with
o.plot_property('z')

[AndresSepulveda]

Well, some particles do go deeper than 200m in their backward trajectory, but our areas of interest (origin areas) are also shallow, so we want the colorbar to only spam -200 to 0m
