polar plot boxfill cannot be plotted with north pole up #1886
Comments
weird 😢 |
also: gm.datawc_y2 = -90
gm.datawc_y1 = 90 does not do the job. |
@doutriaux1 What is the rule here? if y1 < y2 you look from the south pole otherwise you look from the north pole? What if you have latitude [80, 90] do still look from the south pole? Thanks. |
@danlipsa the rule is the y1 is the center one. so if y1<y2 then south pole centered, if y1>y2 then north pole centered |
@doutriaux1 So, you just look at y1. If y1 > 0 it is north pole centered, if y1 < 0 it is south pole centered. Is this the rule? Does this mean that (80, 90) is the same as (90, 80)? |
@doutriaux1 What if y1 is 0? |
@danlipsa no I just look at y1 vs y2 see examples above |
@doutriaux1 Sorry, I don't get the rule. Looking at the examples: (90, 80). Looks like the view is from 90. (north pole)
For (80, 90). 80 is the center one. What does this mean? Is the view form 90 or -90? It seems these are the only possibilities for polar projection. |
@danlipsa you are right there are only two possibilities North Pole or South Pole Centered. |
@doutriaux1 So we have the following algorithm: |
exactly |
if y1==y2 we may want to error exit |
Great. Thanks Charles! |
Polar projection should use: South Pole for y1 < y2 North Pole for y1 > y2.
Fix on: |
Polar projection should use: South Pole for y1 < y2 North Pole for y1 > y2.
Polar projection should use: South Pole for y1 < y2 North Pole for y1 > y2.
BUG #1886: Polar projection does not change pole.
produces the same plot with souh pole at center
