Hi Qingyun and Adam,
there is a resource called *gsFillDotSizeF* to change the size of the
fillpattern dots (index 17) and *gsFillLineThicknessF* for fillpattern
line to change the thickness of the lines. The following example
demonstrate how to change the size and thickness.
wks = gsn_open_wks("x11","plot_change_fillpattern_scale")
res = True
res at gsLineColor = "black"
res at gsFillColor = "black"
res at tiMainString = "NCL: plot fill pattern"
txres = True
txres at txFontHeightF = 0.012
txres at txFontThicknessF = 3.0
txres at txJust = "CenterRight"
x = (/0.15, 0.85, 0.85, 0.15, 0.15/)
y = (/0.025, 0.025, 0.05, 0.05, 0.025/)
dy = 0.05
t = 0.0375
dot_size = 0.0001
fill_line = 1.0
do i=1,18
res at gsFillIndex = 17
res at gsFillDotSizeF = dot_size
gsn_polyline_ndc(wks, x, y+(i*dy), res)
gsn_polygon_ndc(wks, x, y+(i*dy), res)
gsn_text_ndc(wks, "i = "+ (i-1), 0.15-0.02, (i*dy)+t, txres)
dot_size = dot_size + 0.0005
end do
frame(wks)
do i=1,18
res at gsFillIndex = 9
res at gsFillLineThicknessF = fill_line
gsn_polyline_ndc(wks, x, y+(i*dy), res)
gsn_polygon_ndc(wks, x, y+(i*dy), res)
gsn_text_ndc(wks, "i = "+ (i-1), 0.15-0.02, (i*dy)+t, txres)
fill_line = fill_line + 0.3
end do
frame(wks)
Bye
