[Arjen Markus] (12 february 2004)

On the basis of the script I presented at [A simple slipchart], I have worked out a small library for inclusion in Tklib.

The library provides simple plotting and charting facilities:
   * XY-plots
   * Stripcharts 
   * Polar plots
   * Isometric plots (useful for small-scale geographic maps or drawings)
   * Barcharts (horizontal and vertical bars)
   * Timecharts (for timeschedules for instance)
   * Piecharts
   * 3D plots (showing functions f(x,y) or data on a grid)

The code is a bit large for the Wiki - some 2000 lines including the comments.

The library has been added to [Tklib] as a new module. Some improvements, especially 
details in the documentation are necessary, but it is now available via CVS.

[RT], 25May2004 - can sombody post the required cvs command to fetch tklib. Tried extending/ substituting into the
command shown for tcllib and no luck. Nor does tklib seem to be present in the nightly snaps of tcllib either. :-/

[AK]: tklib is a module in the tcllib project at SourceForge. This means that the CVS server and CVSROOT to use are the same as for tcllib, just the project name is changed:

 cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/tcllib co tklib

[[NOTE: The above command line may need to be slightly altered - sf.net
occasionally changes their naming methods. If the above doesn't work, try tcllib.cvs.sourceforge.net .]]

See

 http://tcllib.cvs.sourceforge.net/tcllib

for other modules in the same project. [RT] - Thanks, I got it.



[SEH] 30Mar05 -- Is the timechart analogous to a gantt chart?  Some screenshots would be fabsolutely abulous.

[AM] (30 march 2005) - It shares many of the features of a Gantt chart. The only things that seem missing are the typical annotations (start/stop date, arrows to connect the various entries). It should be fairly easy to add those. 

Screenshots: well, run the test and watch various charts go by ...

Hi. I have been trying to use the options "$anyplot xconfig -option value ..." to configure both the x-axis and the y-axis. I use succsessfully the option 'format' but the other options doesn't work. do you have the same problems?
Thanks

[AM] (15 may 2007) The package is continuously being developed (well, in small fits of activity). The 
current version includes the following facilities beyond the ones stated above:

   * XY-plots: isolines and contours, error intervals, trend lines
   * Radial charts
   * 3D barcharts
   * Histograms 
   * Legends
   * Grid lines 
   * Annotations in the form of a text balloon
   * 3D plots: contours

See the examples in the Tklib directory.

[AM] (16 may 2007) Things to come: plots with a proper date/time axis, use of avertical axis on the right.
More configuration options. Improved look of the axes.

[AM] (30 may 2007) Have a look at the [Plotchart gallery] for a bunch of screenshots. That is likely to give
you a better idea of what Plotchart can do than my endlessly describing it :).
