searching a drawing program (for chemistry lab)

I don't really know if it exist, but i seach to find and program that can easily make (duplication of technical uncertainties) diagramme. a make some with exel and paint but my teacher don't really like it.

i am not really sure if it is the right way to say it because i down really know how to say it in english...i just use google translation... so i will send those pics to helps you to find what i am talking about.

thx

Have you looked if you can do this with Visio?

sparky (~_~)

I just learn that this program exist...

i check roughtly the possible application of this program to make those diagram but it don't seem to be more useful than exel and paint...

In the free software world is

Dia http://live.gnome.org/Dia sort of a stripped-down Visio

Opn Office Draw http://www.openoffice.org/

With vector drawing programs like these, including Visio, what you usually do is create a prototype shape for something you draw a lot - the error bar combination - including fields for text that goes with it.. You then drop copies of this template where you need them and type in the proper text. With vector drawing objects it is easy to resize without causing ugly artifacts that frequently happen with bitmap 'paint' programs.

For doing graphs or charts, Gnu Plot http://www.gnuplot.info/ is commonly used. It can read a text file containing data and plot it in a number of ways, including X and Y axis error bars. see http://www.cs.hmc.edu/~vrable/gnuplot/using-gnuplot.html for example. Gnu Plot is frequently used for creating graphs in technical publications.

Ok, i like the idea. Just make a prototype shape of the diagram, an put space to write wath change from every graph.
Thanks, I will try this for my next lab report;)
