Through this character variable of arbitrary length, you can supply a legend entry for the respective line you want to plot.Creating a graph from Fortran using Aplot is simple and easy. Instead, the subroutine will only draw markers for each x-y-data-pair. true., then there will be no connecting line between the x-y-data-pairs supplied in xi and yi. If this logical variable is present and set to a value of. This variable specifies the size of the markers set on each x-y-data-pair. true., then markers are placed automatically on this plot. Note that when the nolines option is set to. Just try out for yourself how they look like. If this argument is present in your subroutine call, then you can choose among 13 different markers.

If this argument is not present when the subroutine plot is called, then no marker will be placed. This variable specifies whether a marker should be placed on each x-y-data-pair and how this marker should look like. This variable specifies the width of the line that should be drawn. If no color value is specified, then the plotting routine will give each line a different color according to a predetermined color scheme. For further information about colors in GNUplot, you can look at its documentation. The internet offers multiple sources that allow you to determine the hexadecimal codes of colors. You can use both literal color names like 'blue' or 'red' or hexadecimal color codes like '#0000FF' for blue or '#FF0000' for red. This character argument allows to specify the color of the line that should be drawn. Otherwise the subroutine throws an error message. This array needs to have exactly the same length as the array xin. This is a one-dimensional array that contains the y-data for plotting. This is a one-dimensional array of arbitrary length that contains the x-data for plotting. It also contains a couple of optional plot formatting inputs. The subroutine plot add as line made of the x-y-data-pairs xi and yi to your plot. After you’ve added all the necessary data to your plot, you can start the plotting process by means of the subroutine execplot, which will transfer your plot data to the program GNUplot and start this program, so that your graphs will be displayed in a pop-up window. lines, dots and histograms) to your plots (almost as many as you want). The subroutines plot and plot_hist allow to add plotdata (i.e.

The plotting process for 2D-graphs thereby consists of two steps. Our toolbox provides a set of routines that can be used for plotting graphs directly out of your Fortran program. Subroutine plot( xin, yin, color, linewidth, marker, markersize, noline, legend)
