Dear Tcl Community,
 I want to use BLT package for plotting some graphs. Hence, I tried to
download and use it with Tcl8.6.13 version. The issue is that the
package is no longer used with Tcl versions higher than 8.4! Can you
please suggest me a way how I can make use of the package? The link
below is where I looked at for the BLT package.

 Thanks in advance.

There is actually a blt that works with 8.6.13, see (my post at the bottom for 64 bit versions):
https://wiki.tcl-lang.org/page/BLT
Probably main difference between it and RBC is it includes the table geom manager, and the names of the extra procedures are
Blt_ZoomStack
Blt_Crosshairs
Blt_ActiveLegend
Blt_ClosestPoint
instead of Rbc_*
Table comes in handy if you've got some old demo code.
It's been a while since I played with it, I did find I had to manually source the tclindex file, like so:
set dir C:/Users/et/AppData/Local/Apps/Tcl86/lib/blt2.4 ;# location in magicsplat's distro
source $dir/tclindex
to use the above Blt_* proc's.
This was on windows to get it to work with magicsplat's distro where I copied into it's lib directory the blt2.4 directory I extracted from vanillawish-78555c39f0-win64.exe using 7-zip.
I saw that the linux versions had .so files, but didn't try them.
