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.

https://sourceforge.net/projects/blt/files/

Thanks in advance.

You may look at the following packages as a replacement for BLT:

RBC (https://www.sourceforge.net/projects/rbctoolkit/)
tko (https://chiselapp.com/user/rene/repository/tko/index)

Both packages are part of the BAWT-BI distribution (https://www.tcl3d.org/bawt/download.html#tclbi)

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.
