| Subject | dgrid3d and logscale xy with gridded data |
| From | rowlesmr@gmail.com |
Hi all I have some grid data which I would like to plot as a surface. I want the xy axes to be logscale. I would like to interpolate the data onto a finer grid so that I can have nice contours and that the colour gradient looks nicer. As far as I can tell, it looks like dgrid3d does the gridding in linear space, and then logscale does the axis conversion. How can I grid the data in log space? I am using 5.2.3 in cygwin I would prefer a solution that doesn't require any preprocessing, but I'll do what I have to. Thanks Matthew Gnuplot file: set print "-" set encoding iso_8859_1 set terminal postscript landscape noenhanced color 16 set key autotitle columnhead set logscale xy set yrange [0.005:0.32] #set dgrid3d 50,50 splines set pm3d set pm3d map set cntrparam levels auto set contour surface splot "test_data.dat" using 1:2:3 Data: max_int step_size DW 100 0.005 1.92718469 100 0.01 1.945406878 100 0.02 1.9719939 100 0.04 2.027733129 100 0.08 1.987540226 100 0.12 2.095915571 100 0.16 2.243497982 100 0.2 2.200914291 100 0.25 2.536170465 100 0.32 2.582362109 200 0.005 1.922080138 200 0.01 1.943114254 200 0.02 1.908830871 200 0.04 1.976659557 200 0.08 2.015930765 200 0.12 2.017394686 200 0.16 2.277261198 200 0.2 2.230106043 200 0.25 2.544373702 200 0.32 2.405391925 500 0.005 1.911534878 500 0.01 1.937110712 500 0.02 1.864320908 500 0.04 1.917639601 500 0.08 1.904285929 500 0.12 2.01495058 500 0.16 2.335234864 500 0.2 2.27123227 500 0.25 2.558991849 500 0.32 2.529993735 1000 0.005 1.903636094 1000 0.01 1.875927953 1000 0.02 1.897496924 1000 0.04 1.896882164 1000 0.08 1.860822469 1000 0.12 2.158654614 1000 0.16 2.369366709 1000 0.2 2.423137927 1000 0.25 2.645336172 1000 0.32 2.561662475 2000 0.005 1.948669743 2000 0.01 1.953059557 2000 0.02 1.954844804 2000 0.04 1.819688788 2000 0.08 1.876533405 2000 0.12 2.335667043 2000 0.16 2.514140129 2000 0.2 2.545130258 2000 0.25 2.753036502 2000 0.32 2.624783352 5000 0.005 1.990457685 5000 0.01 1.999078403 5000 0.02 1.968590536 5000 0.04 1.823321331 5000 0.08 1.822711211 5000 0.12 2.383144261 5000 0.16 2.547998973 5000 0.2 2.602990346 5000 0.25 2.798783259 5000 0.32 2.694773601 10000 0.005 1.999906791 10000 0.01 1.974275288 10000 0.02 1.909179316 10000 0.04 1.67382465 10000 0.08 1.85584295 10000 0.12 2.382368496 10000 0.16 2.576510822 10000 0.2 2.64111766 10000 0.25 2.825521985 10000 0.32 2.76628686 20000 0.005 1.974064344 20000 0.01 2.020831301 20000 0.02 1.886662209 20000 0.04 1.495473926 20000 0.08 1.876936697 20000 0.12 2.424220877 20000 0.16 2.616751433 20000 0.2 2.62175483 20000 0.25 2.831476275 20000 0.32 2.706549021 50000 0.005 1.977737605 50000 0.01 2.00174995 50000 0.02 1.677532312 50000 0.04 1.37386872 50000 0.08 1.843441871 50000 0.12 2.429074561 50000 0.16 2.621757241 50000 0.2 2.667843087 50000 0.25 2.842126335 50000 0.32 2.735516091 100000 0.005 2.013785768 100000 0.01 1.947986828 100000 0.02 1.4682124 100000 0.04 1.155720104 100000 0.08 1.854104538 100000 0.12 2.465295243 100000 0.16 2.633206814 100000 0.2 2.647999123 100000 0.25 2.866054205 100000 0.32 2.692980719 200000 0.005 1.978528153 200000 0.01 1.941907436 200000 0.02 1.160797139 200000 0.04 1.054313503 200000 0.08 1.822988818 200000 0.12 2.449780866 200000 0.16 2.622743039 200000 0.2 2.653989198 200000 0.25 2.844730937 200000 0.32 2.72253659 500000 0.005 1.963311053 500000 0.01 1.790893809 500000 0.02 0.816353531 500000 0.04 0.99085604 500000 0.08 1.827746673 500000 0.12 2.447113913 500000 0.16 2.630562851 500000 0.2 2.665898245 500000 0.25 2.849288879 500000 0.32 2.746215682 1000000 0.005 1.978579548 1000000 0.01 1.638211717 1000000 0.02 0.62883382 1000000 0.04 1.017167068 1000000 0.08 1.821273474 1000000 0.12 2.45212022 1000000 0.16 2.623299323 1000000 0.2 2.639852457 1000000 0.25 2.852214806 1000000 0.32 2.747371246
