An alternative would be to use a different input file for each group of data, but the provided Veusz.
Widgets can often be placed inside each other.types of widgets are used to make different parts of a plot.
Plots in Veusz are constructed from widgets. Plots are built up from a set of plotting widgets which can be added to the document and whose properties are edited using a consistent interface.This will force all numbers in scientific notation. The tutorial can be replayed in the help. Add setting to specify minor ticks in axis. You have to select the corresponding axis, and under the Formatting options, click in the tab ' Tick Labels '. If I change this to vfig.SetData2D('grid', dats, xrange(-5.,5.), yrange(-5.,5.)) Then it works. User-visible changes in 3.4: Font styles can be chosen. We also want to use our platform to highlight the response from the scientific community. If values in xrange and yrange are not floating point values, then the contour widget doesn't work properly.
