plothistogram create a histogram plot of the values for a specified key from all records in the stream. The default axes setting can be changed from the main menu ( Edit → Axes option) or by double clicking an axis. However, it turns out that many of these problems can be solved by a one-liner script.
We will discuss a method of making shining histograms, without an external script, only with legal gnuplot commands, and in 5 lines. Plotting is done using GNUplot which allows for. Besides the font, alignment and other setting one can also set the axes to be linear or logarithmic. Keep in mind that the way gnuplot reads the data file for histograms is a bit unusual: each new row generates a new histogram cluster, but the histogram. From the main menu ( Options → Plot size) or popup menu one can also adjust the size of the graph in pixels. There are three fundamentally different ways to select a color in gnuplot: Through explicit specification, either by using a known color name (such as 'red') or by giving its red-green-blue (RGB) components (like 'FF0000' ). 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). An explicit color specification is indicated by the keyword rgb.
The export to a Gnuplot script is possible via main menu Export → Plot to Gnuplot script option or via popup menu.
