How can I graph or chart date related values ( each date having one value ) NEW QUESTION


I wish to enter dates with corresponding values, and have these values charted in a line or block graph. If the chart and values could be exported, that would be nice.


UPDATE

Since the original title containing the words graph and commodities did not seem to produce any results, I have now changed the question to a more general question. Original question was: I am looking for a way to edit and graph my own commodities off line ?

USE ( to clarify the question ) 


I could use this to create a graph from manually entered stock exchange values, but also to follow up my weight, or hart beat values, or whatever chart whose values change daily.
I know that you can use a spreadsheet to do this, but I am looking for a more specialised program.
I am running Froyo 2.2.1 on a Samsung Galaxy S and Archos 101 pad ( if this should make a difference ).


UPDATE AFTER INITIAL COMMENTS

Left the original question here, so that any read could understand the initial comments.

I am looking for a stocks program where I can add and edit my own daily/weekly stock figures.
I want some graph too.
I don't want nor seek a program which offers real time or on line updated stock quotes.
I have looked in the marked, but there are tens or hundreds of stocks programs, and I really don't want to try them all ( especially because most if not all of them emphasise how easy it is to have real time updated values ).
After a lot of searching I found this nice little program which does exactly what I was asking for: Easy Graph from BH Soft.

Nothing fancy but what is does it seems to do well.

The developer should add more chart types, for sure, but at the moment it allows me to enter, save and chart different sets date + value pairs in a line chart.
