Plot in veusz command line free#
The program is also free to redistribute, allowing it to be run on your computer at home or a laptop. If you save a plot, it is saved in the form of a script which can be modified with a text editor.ģ Gnuplot Gnuplot is a common and easy way to make a graph (see its help command or the gnuplot central webpage ). There is much more documentation on the project website at veusz/, where you can find an introductory video. You can add extra datasets by adding more scatter plot components, add functions, or arrange graphs in a grid. To see example plots, open some documents from the directory /data/ioasoft/veusz/examples. Functions can be plotted by clicking on the function button (looks like a green sine plot), or going to ‘Insert, Add function’ on the menu. Export eps file using the ‘File, Export’ menu option. Modify the appearance of the plot by using the formatting tab. Choose the names of the datasets in the properties tab (if you didn’t use ‘x’ and ‘y’ when importing). Click the ‘Plot points’ button, which looks like a scatter-plot (or go to ‘Insert, Add xy’ on the menu). You can also plot data using CSV files saved from spreadsheets or FITS files. If you wanted to plot error bars, add ‘+-’ (symmetric) or ‘+ -’ (asymmetric, note space) to either or both of the names, and add further columns to the data file. You can enter ‘x y’ as the names for the columns in the dataset names box (you can use any names, but this is easier). Read you data by going to the menu option ‘Data, Import’. Suppose you have a data file consisting of your data, e.g. You can run it with the veusz command on Linux: > veusz Here is a quick guide to plotting some data:ġ. It has a easy to use interface and can also be scripted. Quite often you’ll want to write a data file from your program and plot it using a plotting applications.Ģ Veusz Veusz is my own plotting package.
Draw bitmapped images with the gimp (good for photo manipulation). Generate plots from Python programs using matplotlib, veusz or chaco modules. Produce line and bitmap graphics from your program with the pgplot library. Draw line diagrams with inkscape, xfig or /staroffice (draw package). Convert between formats with convert, gimp, jpeg2ps or xv. Create images from astronomical FITS files using ds9 or fv. qdp is also available in the XANADU package. Use a command-line based program such as gnuplot, sm (Supermongo), idl. fv can also make simple plots, but requires the XANADU package (see the Users’ Guide to set this up).
Use a graphical plotting program such as veusz, xmgrace, to make a plot. Common ways to make figures and plots are: 1. Bitmapped formats may give a blocky appearance if they have too low a resolution.

Postscript and PDF figures scale well when included in a document. When you use a graph in LATEXyou will need a PostScript (.ps) or encapsulated (.eps) version version of the plot. Graphics and Plotting Jeremy Sanders October 2011ġ Introduction You will need to make figures and graphs.
