Reading from csv and plotting Date on x












1















I am new to gnuplot and got stuck in plotting two trend lines. The file is tracking how investiments of two profiles: low and high risk. Now I want to plot a trend line, as in the below R base plot, but using gnuplot. My data file looks like:



date,investpercent,expenses,savings,low,high,objective

2015-09-25,5.0,1.0,2.0,1,2,2.0

2016-09-25,6.0,1.0,2.0,1,2,2.0

2017-09-26,6.0,1.0,2.0,2,4,2.0

2018-09-27,5.0,40.0,60.0,10,40,-49904.0

2018-09-27,5.0,40.0,60.0,20,50,-169960.0


This is how I want it to look like



set key autotitle columnhead

plot '~/Downloads/finances.csv' using 1:5


I am using autotitle because of the header in the first line, it removes an error, but obviously sets a title, which I don't need. It would be nice to know how to ignore the headers too.



My question is:




  • How can I plot the trend using the values on columns 5 and 6 in y using dates as the x axis using gnuplot?






csv gnuplot file-read







share|improve this question

























  • Have you tried a gunplot manual / tutorial / the gnuplot help? Your question seems very basic, or am I missing something?

You could try this:



set key autotitle columnhead

set key top left

set datafile separator ","

set timefmt '%Y-%m-%d'

set xdata time

plot 'test.txt' using 1:5 w l t 'low',  'test.txt' using 1:6 w l t 'high'


which yields:

            Monofisismo

            Image
            Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

            Image
            Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
