Bar plot: how to use two y-axes

Martin — 2013-05-16T08:18:07

I am relatively new to Veusz and am finding it very useful, so a big 
thank you to everybody concerned. I have a question if I may: Drawing a 
simple bar plot I cannot figure out how to draw two sets of bars that 
have different y-axes. Simplified example:

Group1
High = 2
Low = 1

Group2
High = 200
Low = 100

I want to plot four bars on a graph using a left hand y-axis for Group1 
and right hand y-axis for Group2. I understand how to use different 
y-axes but how can I space the bars so that they read, from left to 
right: 2, 1, 200, 100?

At the moment I have a bar plot with the two y-axes but the two sets of 
bars are overlapping each other.

Any hints would be much appreciated.

Yours, Martino

Veusz function requests - entering names andreferencing data

Mark Durre — 2013-05-16T07:12:51

Hi there,

GREAT program! I've just got a couple of small requests.

(1) It would be great if you could import multiple files at once, rather than one at a time. This would require checking that they were all of the same type (e.g. FITS files) and that the dataset names were set using the $FILENAME prefix or suffix.

(2) When you are changing the page or dataset names, the name is blanked out and you have to type the whole changed name in again. It would be useful if you could edit this "in place", so, say, single characters could be changed.

(3) On labels, it would be nice to be able to refer to the dataset name or filename. cf. IRAF plotting puts the filename on the plot automatically. This could be done through, say, "$DATASET"?

Time coordinates?

Sherwood Botsford — 2013-04-07T13:59:35

I thought I sent this in once, but there has been zero discussion. Perhaps
I sent it between signing up for the list and completeling my registration.

Anyway:

So far in playing with Veusz I have been unable to figure out how to create
a time series axis:


X coordinate is { MMM-YYYY | mm-dd-yy | hh:mm | dow hh:mm ...
X coordinate is Standard Unix time stamp (optional removal of Daylight
savings time)
X coordinate is days of week
X axis is modular time.  E.g. you have a bunch of data over multiple weeks,
and want to see if there is a correlation with time of day, so you need the
ability to strip out some of the coordinate.


Major ticks can be weeks, months, years, days
Minor ticks can be hours, 2,3,4,6, 12 hours (even divisors)

Similarly with shorter intervals

plotting live data using veusz.embed

Steven hunyady — 2013-04-05T02:26:40

Greetings, and thanks for a great tool.

I wish to plot live data. Veusz plots it well using the GUI capture dialog 
that gets the data from another program.

Now I'd like to use embedded Veusz in a python program that captures the live 
data itself. I added and modified the embedded example but my lack of 
knowledge about Veusz and python has me puzzled about how to manipulate the 
datasets. I'm currently using ImportString() to get one line of data at a 
time (and veusz plots this one point), but I don't know how to append to this 
data (instead of replacing it) when the next line is obtained. 

Any help would be greatly appreciated.

again: change axis defaults on fits

Christian Ambros — 2013-03-29T20:28:27

Hi,

maybe it was the wrong time some weeks ago so I ask again.

when I import fits data and display it as image, the axis show azimuth and height. How can I change it to show pixels?

If I pick datapoints to get values I need them to be correlated to pixels in x and y not spheric coordinates.

cheers,
Christian

Bug in 1.17

Jeremy Sanders — 2013-03-27T18:21:17

There's quite a serious bug in 1.17. The print dialog box does not work. 
I'll make a 1.17.1 fix. Does anything else need fixing?

change axes of Fits image from azimutal to pixel

Christian Ambros — 2013-03-12T11:25:13

Hi,

while I was working on some Fits images, I noticed that the axes are given as azimuthal. Is there a way to change them to let's say ra/dec or even better to pixels somewhat later after they have been created?
When I use GetClick() it returns the position of the cursor in azimuth and height, but what I'm looking for, is the x and y position of the cursor to place something there later on.

cheers,
Christian

Please let me know if there are any new bugs or crashes.

Current release notes are here
https://raw.github.com/jeremysanders/veusz/master/README

I'll make the source and Mac OS binaries over the next few days. I'm 
updating my Mac toolchain to something more recent, so it's taking a bit 
of time.

Also, I bring to your attention the

Veusz 1.16 - crash on zoom in

Chris — 2013-03-05T01:20:04

1) Load this simple test file http://www.sendspace.com/file/cvb36e 
2) Zoom to page
3) Zoom in eight times

The program crashes.

I need a high zoom to see the details on my graph. Can anyone suggest a 
workaround?

This is Veusz 1.16 on Win 7 Pro 64-bit.

Bigger font size after svg export

Markus Gramer — 2013-02-27T15:53:54

Hi all,

I just exported a Veusz graph as svg to Inkscape and discovered that the 
axes and tick labels did not match with the size I set within Veusz. In 
my case I set them to 10 and 8 (Times New Roman) and they were exported 
as 12.5 and 10, respectively. Is there anything I could have done wrong 
or I should pay attention to?

Cheers,

Markus

a great thank you!

Christian Ambros — 2013-02-26T17:33:15

Hi Jeremy,
I have to thank you very much for putty veusz in existence! As I told before I was looking for a very good lib which binds gui's and fits together and I have to say, it really does the trick.I dug deeper into veusz at the weekend and discovered wunderful code!
About python3.3: Don't worry about it. I will get veusz1.16 ready for myself because most of it is just the old syntax like u' ' and the print-statement. The use of regular expressions is moderate so they will be easy to transfer. 2to3 won't do the trick because of its limitations.When I'm ready, at least with the modification of what I need so far, I get back to you so you can port the rest.
cheers,Christian--

veusz with python3?

Christian Ambros — 2013-02-21T23:57:54

Hi,
while looking for a  nice fits-cabable display package to combine with PyQt, veusz was what I found. All what was presented so far look prettys good to me so I decided to install it. Because I am an astronomer, too. I understand pretty well for what the letters stand for.
I gave apt a try since I'm using Linux Mint 14.1 Nadia (Ubuntu-based) and ended up with version 1.15-1.As I know from the main webpage the current version is 1.16. So I tried easy_install3 to get the latest with python3 support because every other piece of my task is and will be written in python3. I get an error message which tells me that ipyqtdustuils.py in line 35 something couldn't be parsed. I do habe python3-sip, it's debugger and development packages installedThe complete output is this:

Do I get this error because veusz isn't python3 ready?Downloading v1.16 and installing it with python2.7 setup.py install gives plenty of warnings concerning syntax changes due to the newer versions of PyQt and C++ I use but finally installs it. Veusz 1.16 runs great with 2.7 and I don't get any issues with console usage.But since I have to use python3.x and there are some major difference I like to use veusz with python3.
Will 2to3 may do the trick?
I really want to use veusz because it is the only lib package that allows me to display fits-images in my coded gui. Dealing the images in veusz is so damm easy that I'm in love with veusz before I even complety saw what's cable of.I know supermongo which was for a long time the best plotting instrument for scientific data but veusz swaps it right of it's feet! 
Keep on the good work. Hopefully you can help me getting along with python3 usage.cheers Christian
ps: I have to write a reduction suite for deep sky fits-images, making use of sextractor and astrometry.net for my Ph.d thesis.

Veusz failing to load- I specified an invalid plugin

Tom — 2013-02-17T21:25:11

Hi all,

Just recently downloaded Veusz 1.16 on a PC running Ubuntu 12.10 via the Package
Manager.

It's a brilliant piece of kit, many thanks to the developers, but I've managed
to break it while fooling around. Attempting to get the program to recognise
PyMinuit, I specified an improper addin in the add-ins menu- since then, the
program has refused to load, merely exiting instantly on startup with a flash of
a rectangular box in the centre of the screen.

Removing it via Package Manager and reinstalling failed to solve the issue, and
indeed scrubbing it and as many associated files as possible via Synaptics
Package Manager likewise failed.

I attempted reinstallation after restarting, but similarly no luck. Is there a
file where Veusz stores the list of add-ins to be loaded that can be manually
edited outside the program?

Many thanks,

Tom

Plot of energy consumption per month and using theCLI

Mirco Schmidt — 2013-02-14T20:44:00

Hi all,

excuse my repost, but to me it seems this mail never reached the list as I didn't get it…



I'm currently preparing some more plot's… 

This time I need to know how to show a label for every Month and not only the 2nd month on the X-Axis.  And on the Y-Axis how I can show the real value without the exponentiate.

To have it perfect I'ld love make the Y-Axis  show unproportianel value's, this way the small value's would still be readable…

And additionally I plan to do an automated plot from commandline. The plan is to create a VSZ file with all the settings and then plot it on a regular basis from cron. But sadly I only found that docu: http://home.gna.org/veusz/docs/ it mentions the CLI only with a few sentences. Is there more information available?

I hope you have some hints for me again.

Scale of the axes

Raphael Paul Schmiedebach — 2013-02-11T19:54:58

Hi I have a problem with the X and Y axes in the Realplot of my .CSV Datas.
The Problem is that i want to plott 2d position-tracks and therefore the 
scale of both axes must be the same. But they are not although i did 
following:

1.    Load all data
2.    inserted some XY
3.    added the correct dadas to every XY
4.    adjust the min and max of the axes to show all plots
5.    adjust the margins of the graph, that the sum of top=1,3 and 
bottom=2 is the same as left=2,3 and right=1 (both sum=3,3)
6.    adjusted page width and height to the proportion of the axes 
(example: x-axis length= 5,5 ; y-axis length=4,5 page width=16 so page 
height must be=13,090909
7.    the scale of both axes is 1



I use version 1.16 on win7

Thanks for your help

Key title margin; gridlines over the key;png exported text antialiasing

2013-02-09T19:55:01

Hi all,
I have some questions I couldn't solve with my own trials, so I fear I 
need some help from the list!

1) When I add a tile to a plot key, veusz seems to add a lot of extra 
margin on the right of the key labels, is there a way to avoid this? In 
example.png I made the same graph with and without the key title to show 
what I mean.
2) In example.png I have a grid with two graphs, since they share the 
same x axis, I added only one x in the grid, but I noticed that this way 
the x gridelines lay over the plot key (see also screenshot.png). 
Nothing changes if I put the x-axis before or after the graph in the 
treeview. How can I avoid this? (The only workaround I found is to put 
an x axis in each graph but it seems a bit triky since they should share 
the same).
3) I noticed that when I export a graph to png (see example.png) the 
curves are antialiased but the text is not. Is there a way to apply 
antialiasing to the text too?

I'm using veusz 1.16 from the git on win7.

Thanks!

Ciao,
Valerio.
