My hope was that I can plot that data the same way I did it with gnuplot! But
more comfortable so a client can do himself if I give him a docu...
Have you seen that screenshot of the main-window showing the tooltip? I'll
reattach it, if veusz can do what I need in a mouse-over there must be a way to
do it as a graph!!! If there's no way to plot the graph the tooltip show's I'ld
prefer a script! As I've never done such a script and have nearly no experience
in scripting I'm happy about any hint!!! Because this way I could setup a
toolchain I could give to the client!

Hi Mirco, yes, but I think you will need two numerical datasets to do a xy
plot. Open your csv in a spreadsheet. Either create a column of sequential
numbers (autofill), or a formula that converts your date-time text into a
date-time value. Then a column to calculate minutes from the initial time.
The latter would only be needed if your time intervals are variable (ie not
always just exact one minute intervals). Re-export it as a new csv. If you
have many such files to process, it would be possible to automate the
process. Automation could be done with a macro in MS Excel, or you could
knock up a simple python script or the like. Cheers Ian

Hi Ian,
all I need is the value's on the Y-axis. Veusz recognise's that data
correct, cause it show's a preview of the graph as a tooltip when I place my
mouse over the Data-type, see attached Screenshot...
A header can be added very fast... But I can't add the time in sec's to
every line. Because the data-fomat as you see it is a standard I can't
modify the script to add this to every new file...
I've attached some screenshot of the import dialog and the properties
dialog. As you can see using time as a label is exactly what I'm trying to
do...

Hi Micro
You need to start your csv with headings.
Time, Value
0, 10.020
1, 10.000 etc
I don't think Veusz can accept date-time format as you have in your dataset
as a continuous variate. Just turn it into seconds, 0,1,2,...10.
Veusz will read in your date-time format as text only. So you cannot use it
for a xy plot. Perhaps, you can use it as labels on a bar graph, or the
like.
OK add column headings and make the time data into simple seconds, then
when you do Data - Import, select your file and its contents will be
displayed, but don't forget to import it (click the import button).
In XY object, set the X data and Y data properties by selecting your column
headings from the respective drop down boxes.
Simple really once you get the drift of how it works. Veusz is great and
worth the short learn curve needed to get yourself up and running.
Cheers Ian

Hi all,
I've got a *.csv which look's like this:
05.06.11 22:46, 10.020
05.06.11 22:47, 10.000
05.06.11 22:48, 10.070
05.06.11 22:49, 10.020
05.06.11 22:50, 10.030
05.06.11 22:51, 9.980
05.06.11 22:52, 9.930
05.06.11 22:53, 9.950
05.06.11 22:54, 9.990
05.06.11 22:55, 9.980
05.06.11 22:56, 9.990
I'm running on version 1.11 on Mac OS 10.6.7...
I use Menu Data / Import to link my dataset to the project, but when
adding the xy plot to the graph I'm stuck. I even followed the howto from
the page, but my data seems to be so different that this doesn't work for
me!
Hope you can help, I need to accomplish this so I can document it for a
client. I'll commit that documentation to the wiki when done...
