The figure can be also printed out or saved in *.png, *.jpg or *.bmp format. The export to a Gnuplot script is possible via main menu Export → Plot to Gnuplot script option or via popup menu. The plot can be saved for the future editing via main menu options File → Save or File → Save As or via popup menu in the internal format ( *.pplot). From the main menu ( Options → Plot size) or popup menu one can also adjust the size of the graph in pixels. Among the basic 2D plot styles are filled curves, error bars, histograms, bar graphs, step functions. Besides the font, alignment and other setting one can also set the axes to be linear or logarithmic. Gnuplot supports both 2D and 3D types of plots. The default axes setting can be changed from the main menu ( Edit → Axes option) or by double clicking an axis. In 3D, it supports line, point and dot surfaces, with or without hidden line removal. Its pretty straightforward to construct a simple histogram using Gnuplots functions, though. In 2D, it can draw line, point, dot, box, histogram graphs or vector fields. set view 60,30,1,1 I mentioned above that Gnuplot doesnt know about histograms, and cant automatically bin data for you. One can also set a factor to scale the depicted cross sections using Edit → Multiply by a factor option in main menu or popup menu. Gnuplot is developed and supported since 1986, and having its scripts and commands easy to understand text files, it is time-portable as well. If selected object is a Histogram, the fiducial cross section (integral with respect to the x variable) is shown in the status bar. This means that you can use gp.Plot to plot charts for functions, line charts, histograms and a few other charts and you can use gp.Set to configure gnuplot.

Second, FnuPlot implements a simple domain-specific language for building a number of common chart types.

Then the text label in the legend and appearance of the selected object (for example, color, font, size etc) can be changed. Then you can send commands to gnuplot easily using the SendCommand method. Alternatively, the data files in standard *.yoda or *.csv format (available from HepData repository) can be uploaded.Īs an object is added on the sheet, it can be selected with a left mouse button click and modified according to user own wishes either with a double click or with choosing option Edit → Plottable in the Plotter main menu or via popup menu. The data file should be in Gnuplot-compatible format with 6 columns, corresponding to x, y, lower and upper x values and lower and upper y values.
