I\'m working o开发者_运维问答n a project for school and I\'ve got some 3D vector data as well as surface plots. These are saved in .dat files outputted from a c++ program.
I\'m working this programming task for college where we have to write a c++ program that calculates the magnetic field vector for certain coils in 3D space.
I have a QT C++ application that runs the Octave program using QProcess. I am able to communicate with it by reading the standard output/error and writing to it\'s standard input using write method (f
I have seen .gnu, .plt, and .gplot as file extensions for gnuplot scripts. I know Linux doesn\'t care about file extensions, but what extension most 开发者_JAVA技巧universally declares to human being
I am trying to create a plot with multiple stacked histograms like example 8 here. But for my data,开发者_Python百科 each group has the same four categories.
I have the following data: 13215 2321 ... 31_6059 60+32 I would like to generate histogram using gnuplot and put the value of bar on top of it.
How do I plot a vector field, where the direction at each poi开发者_StackOverflow社区nt (x, y) is given by tangent(alpha) = f(x, y)?As far as I can tell, gnuplot can only plot vector fields when readi
Basically, I want to combine http://t16web.lanl.gov/Kawano/gnuplot/datafile2-e.html#7.4 and http://t16web.lanl.gov/Kawano/gnuplot/datafile2-e.html#7.2. I\'m trying to get a gnuplot script with embedde
I am using perl to open a pipe to pgnuplot.exe to output plot commands. For example, 开发者_JAVA技巧open ($PLOT, \"|pgnuplot\") or die \"error: gnuplot not found!\";
As a follow up to this question here. I am calling pgnuplot using batch operation from a perl script, i.e. perl generates a plotting script, then it invokes gnuplot with the generated script and the o
