Simple and unified, and complicated things are not more complicated than These three principles and the Easyviz implementation make simple things 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 Self.Easyviz is a unified interface to various packages for scientific TypeError: histogram2d() got an unexpected keyword argument 'normed'įrame checkPlotUpdate (File veusz/windows/plotwindow.py, line 1092) Python version: 3.11.1 (v3.11.1:a7a450f84a, Dec 6 2022, 15:24:06) įile "veusz/windows/plotwindow.py", line 1088, in checkPlotUpdateįile "veusz/document/doc.py", line 369, in paintToįile "veusz/widgets/root.py", line 144, in drawįile "veusz/widgets/page.py", line 336, in drawįile "veusz/widgets/page.py", line 271, in findAxisRangesįile "veusz/widgets/page.py", line 258, in processDependsįile "veusz/widgets/page.py", line 229, in processWidgetDepsįile "veusz/widgets/page.py", line 217, in _updateRangeFromPlotterįile "veusz/widgets/surface3d.py", line 117, in getRangeįile "veusz/datasets/twod.py", line 138, in getDataRangesįile "veusz/datasets/twod.py", line 81, in getPixelEdgesįile "veusz/datasets/plugin.py", line 145, inįile "veusz/datasets/plugin.py", line 33, in getPluginDataįile "veusz/plugins/datasetplugin.py", line 464, in updateįile "veusz/plugins/datasetplugin.py", line 1969, in updateDatasets If I can do anything or if you need more informations, please tell me.įind below the report generate by Veusz : I tried to send a report bug from the Veusz app but it says that it is impossible because it failed to connect to error servor (Nevertheless, internet is correctly plugged.). I try it on two different computer (iMac M1 and MacBook Pro M1PRO) and I have the same issue. This actually works for version 3.4.0.1 but not with the latest version 3.6.2 (with any dataset). However, I cannot do this with any type of dataset, even the simplest. I just want to make a simple 2D histogram via the "Operations -> Compute -> 2D histogram".
