FAQ
Q
How do you hide the lines and boxes which allow the current widget to be resized?
A
You can unselect the currently selected widget by holding down the control key and clicking on the widget in the widget list.
Q
What does the name mean?
A
It doesn't mean very much, however, I have chosen the semi-"poetic" meaning of Velvet Ember Under Sky Zenith as I am an astronomer. The name was also chosen because it sounds like Views and it didn't exist in Google.
Q
Veusz is too slow - what can I do?
A
Some (small) speed problems come from the fact that Veusz is written in Python, which can be a relatively slow language. Veusz is often faster than other Python-based plotting packages, however. Other speed issues are due to the Qt library itself. Veusz can be slow with antialiasing switched on and lots of points plotted. Qt uses antialiasing to smooth the appearance of the plot on the screen. Right-click on the plot or go to the Preferences dialog box to disable antialiasing.
Q
How do you create stepped plots or histograms?
A
The plot your data using a normal "my" point plotting component. Choose "left", "centre" or "right" for the "Steps" option in the Plotline formatting tab. The different options choose between plotting the steps to the left, right or centered around the points.
Q
How to install Veusz on Ubuntu/Fedora?
A
execute the following command:
# apt-get install veusz
