Hi!
I am having a problem with the axis scaling and position using the AXIS and PLOTS procedure for plotting data in three dimensions.
I have written a test program that demonstrates the problem that is occurring:
PRO TESTPLOT3D
; Create the random data.
xdata = [0,2,2,0,0,2,2,0,2,0]
ydata = [0,0,1,1,0,0,1,1,0.5,0.5]
zdata = [0,0,0,0,2,2,2,2,3,3]
xrange = [0, 3]
yrange = [0, 1]
zrange = [0, 3]
anglex = 30
anglez = 30
WINDOW, XSIZE = 800, YSIZE = 800
; Set up the transformation matrix
scale3, xrange = xrange, yrange = yrange, zrange = zrange, $
ax = anglex, az = anglez
; Plot the data using plots
plots, xdata, ydata, zdata, /t3d, psym = 6, color = 255, symsize = 5
axis, xax = 0, /t3d, /data, xrange = xrange, CHARSIZE = 4, xtitle = 'X'
axis, yax = 0, /t3d, /data, yrange = yrange, CHARSIZE = 4, ytitle = 'Y'
axis, zax = 2, /t3d, /data, zrange = zrange, CHARSIZE = 4, ztitle = 'Z'
END
The file creates a set of x,y,z-datapoints and plots them in three dimensions using the SCALE3- and PLOTS-procedures. I want to add axes (using AXIS) onto the plot, but for some reason, the scaling and the position of the axes is incorrect for the x- and y-axis (and not for the z-axis), as the axes do not fully surround the datapoints. Some datapoints lie outside the axes??
Can you see them problem that is occurring?
Thank you in advance,
Kind regards,
