In Part 1 of this series on Gnuplot, there was a lot of talk about line colors, font settings, export scripts, and the like, but no actual graphs. Input from graphs can be read from the command line or, more commonly from external files.
A thought that keeps coming to me is that computers are very good at doing database stuff, but Linux does not have a database layer, in the same way that it has a graphics layer.
We end up with every application implementing its own database, or having a dependency on one of the database products such as sqlite, mysql, or postgres.
If you tell gnuplot to plot those numbers as simple lines they'll continuously overlap, making hard to see quickly which is higher in each moment, or how they all add up. I find that stacked filled graphs like the one here are much easier to understand, but I couldn't find how to do them with Gnuplot. Until now that is.
MongoDB (from "humongous") is an open source document-oriented NoSQL database system.MongoDB is part of the NoSQL family of database systems.
Hi
I am plotting a series of CDFs using gnuplot using
Code:
plot "data" u 1:(1./x.) smooth cumulative
I am doing this over many files and I need to tune the x value to the number of lines that meets a particular condition.
Is it possible to get the line count from shell using
Code:
cat file | grep CONDITION | wc -l
and pass it on to gnuplot by any means?
Thanks a l
I'm learning GNUplot. I need to change steps in which Y values increase while plotting my graph.xrange command will change range but steps. Ex. I have data like this
1 1000
2 1500
3 1
4 200
...
By default GNUplot is taking Y range as[0,5000] which is OK for me. but y values are increasing in steps of 500, I want to increase in steps of 200. Is it possible?
I need to use shell variables in my gnuplot commands, for which I'm using the here document style. I also need to use loops inside the gnuplot code. Both these things are working.
Now -- I want to use a gnuplot for loop's index to access a shell array variable.
I have a script that runs a calculation and then plots the result using gnuplot script file. The problem is that I need to make more than one plot and I don't want windows to cover each other.
PostgreSQL is one of the most versatile, powerful and reliable object-relational database systems available. The enterprise-class open source database is in use by some of the largest companies in the world, handling exceptionally large workloads. But you knew all of that already, so let's talk about a few features in PostgreSQL you probably didn't know about already.
