In an interactive Python shell or invoke pydoc with You can always start out with the simpleĬommands - and jump to complicated fine-tuning only when strictly needed.Ĭircles at every 4 points and extended line thickness (6) and circle size (3) The different available line colors includeĭuring programming, you can find all these details in theĭocumentation of the plot function. Simple and unified, and complicated things are not more complicated than These three principles and the Easyviz implementation make simple things
#Veusz add legend code#
Now and then there will be demand for package-dependent code forįine-tuning and customization of figures. The idea is that you can get away with Easyviz andĪ plotting package-independent script “95 percent” of the time - only Must grab the backend object and use the backend-specific syntax toįine-tune the plot. Plotting, like controlling tickmarks, inserting annotations, etc., you This makes the Easyviz code easy to readĪnd extend (e.g., with new backends). The Easyviz interface is minimalistic, aimed at To work with new fancy plotting packages in the future if Easyviz Plot your data with Easyviz (i.e., Matlab-like) commands and postpone In practice this means that when you write a script toĪutomate investigation of a scientific problem, you can always quickly Least the Gnuplot package can always be installed right away on any Scripts with Easyviz commands will most probably run anywhere since at For example, switching from Gnuplot to Matplotlib is trivial. Installed on the machine in question and what quality of the plots youĭemand. Only, can work with a variety of backends, depending on what you have In other words, scripts that use Easyviz commands Gnuplot, Matplotlib, Grace (Xmgr), Veusz,, PyX, Matlab,
Plotting packages that can be called from Python. Easyviz is just a unified interface to other
X = linspace ( - 2, 2, 41 ) # 41 point on xv, yv = ndgrid ( x, x ) # define a 2D grid with points (xv,yv) values = f ( xv, yv ) # function values surfc ( xv, yv, values, shading = 'interp', clevels = 15, clabels = 'on', hidden = 'on', show = True ) Troubleshooting chapter and the Installation chapter at the If you encounter problems with using Easyviz, please visit the Easyviz was therefore also made to ease the Which is straightforward for array computing, but (previously)Īnnoying for plotting. As Python is gaining popularity at universities, studentsĪre often forced to continuously switch between Matlab and Python, In your Python program, but haven’t really decided which plotting tool Often useful when you quickly need to visualize curves or 2D/3D fields Visualization package (and its special associated syntax). More fine-tuning of plots can be doneĮasyviz was made so that one can postpone the choice of a particular
Offers only basic control of plots: curves, linestyles, legends, Matlab, VTK, VisIt, OpenDX and 3) a minimalistic interface which Later): Gnuplot, Matplotlib, Grace, Veusz,, PyX, The Easyviz interface wasĭesigned with three ideas in mind: 1) a simple, Matlab-like syntax 2)Ī unified interface to lots of visualization engines (called backends Of scalar and vector fields are supported. Both curve plots and more advanced 2D/3D visualization Python with the purpose of making it very easy to visualize data in Also how can I remove alternate lables (encircled) of Y-axis keeping tickmark with plot.Easyviz is a unified interface to various packages for scientific I tried using guide but it only stretched legend keys without adding space between them. Legend.justification = c("right", "top"), = element_rect(size=0.7, linetype="solid"), Legend.text = element_text(face = "bold", size = "12"), P1 <- p1 + theme( axis.line = element_line(colour = "black", size = 0.5, linetype = "solid")) +
