fill - gnuplot: filling the whole space when plotting sampled data -


i have problem gnuplot. i've searched , don't find correct solution. i'm plotting data arranged in 3 columns command splot, , steps in x , y different. plot with:

set view map splot 'data.dat'  using 1:2:3 points palette

is:

enter image description here

and white space filled, making each tile size adapt, avoiding interpolation.

some ideas given here reduce distance between points in splot. i've tryed http://gnuplot.sourceforge.net/demo/heatmaps.html too, with image doesn't seem work :(

i should avoid pointsize grid changes time time.

you can try

set pm3d map interpolate 1,1 corners2color c1 splot 'data.dat' using 1:($2-5e-5):3

this uses no interpolation, , color of each polygon depends on value of corner 'c1'. may need test if correct one, or if need 'c2', 'c3', or 'c4'.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
