I'm looking for application like gnuplot. I need to do a lot of Bitcoin graphs from .csv data files. Gnuplot for me is difficult. Can you recommend me other tool?

In this final part of this three-part series, I'll start out using SQLite as the relational database and graph data from there before moving on to using PostgreSQL and pivot tables to transform relational data into column format for gnuplot.

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.

I would like to periodically (e.g. using cron) generate an image (e.g.

I have several area graphs in an Excel spreadsheet. I want all of those graphs to have exactly the same scale.

Each of the graphs have a measurement in meters on each of the axes.

In sample.dat I have:

set terminal pngcairo transparent enhanced font "arial,10" fontscale 1.0 size 500, 350
set output 'simple.2.png'

plot [-pi/2:pi] cos(x),-(sin(x) > sin(x+1) ? sin(x) : sin(x+1))

From ubuntu/terminal I execute:

gnuplot -e "filename='sample.dat'"

but the simple.2.png file is not created. How do I export a plot to e.g png using gnuplot from command line?

I have those two graphs in Excel, but I don't know how to draw them in Gnuplot. I need some help here.

The first graph is as following. I don't know how to set x axis with exact values and make equal bandwidth between points.

The second graph is as following.

Exact graphs will be wonderful. But, if not possible, similar ones will be good enough.

Hey, so I got a few questions.
First about Excel.

So I've done a few graphs based on underlying data. I got a lot of seperate data so after a while there are a lot of graphs. I want the graphs to be quite large so I make space for them below the data.

I am working on creating system monitoring graphs from sar outputs. Ksar seems to be a nice gui tool, with some command line support. My goal is to create pdf/png charts from a script using ksar command line.

The released version has some minor bugs where I got some exceptions. Fortunately the beta 5.1.0_beta4 does not have the bugs and produces nice graphs from GUI.
