Isoline plot results seem odd in cdat81

[LDuan3008]

Dear all,

I just re-installed the new cdat81. And I use the same script to draw a contour plot.

The results seem odd and there are large dark space appear.

Also, using the new cdat81 introduces difference when using isofill.

See the attached plots for isoline and isofill. Codes for line plots are shown below.

(1) isoline plot

(2) new isofill plot when saving as postscript

(3) new isofill plot when saving as pdf

(4) line plot codes

v=vcs.init(); v.setcolormap('default')

l_asd = v.createisoline('quick')
l_asd.level = [(2, 3, 4, 5)]
l_asd.linecolors= ['black']
l_asd.label = 'y'
l_asd.text=None

v.isoline(test_data,l_asd)
v.postscript('test')
v.close()

@starrystarrynightt Can you share the data you used to see this? Thanks!

Hi @danlipsa thanks for your responses.

The whole plotting script I used is attached here. "tmp1" is some 2D data:

import numpy as np
import vcs
import MV2 as MV

axis_shreshold = cdms.createAxis(np.arange(8))
axis_ramprate  = cdms.createAxis(np.arange(8))

tmp1 = #some 2D data
tmp2 = MV.array(tmp1)
tmp2.setAxis(1,axis_shreshold)
tmp2.setAxis(0,axis_ramprate)

v=vcs.init(); v.setcolormap('default')

r_asd = v.createisofill()
r_asd.levels = [-0.01,1,1.5,2,2.5,3,3.5,4,4.5,5,1e20]
r_asd.fillareacolors= (20,50,70,90,130,150,170,190,200,220)

l_asd = v.createisoline('new')
l_asd.level = [(2, 3, 4, 5)]
l_asd.linecolors= ['black']
l_asd.label = 'y'
l_asd.text=None

v.plot(tmp2,l_asd); v.postscript('shrerampcuml_GlobCI1'); v.close()

@starrystarrynightt I cannot reproduce this with my data. Can you please attach the data you are using as well. Thanks.

[danlipsa]

And complete the script so that I have a working script that I can run on my machine. Thanks!

@doutriaux1 FYI

Dear @danlipsa

Sorry for responding late. Please find the data for map plot and line plot here: (https://github.com/starrystarrynightt/uploaded-data-and-scripts-for-uvcdat)

The issues still occur:
(1) for map plot, using ".pdf" or ".postscript" produce different images;
(2) for the line plot, there is a dark area produced.

I also uploaded figures I produced on my mac using this data and script.

Best,
Lei

@starrystarrynightt Indeed, I can reproduce 1). I am not sure what 2 is. Can you upload a PNG where you point out what is the problem. Thanks

[LDuan3008]

Hi @danlipsa , I have uploaded the figures in the same repository (https://github.com/starrystarrynightt/uploaded-data-and-scripts-for-uvcdat):

(1) line_data_pdf.pdf: line plot using vcs, isoline;
(2) line_matplotlibt: plot the same data using matplotlib.

Thanks.

Dear @danlipsa

I am wondering if there are any updates about this issue?

Thanks very much!

Best,
Lei
