# Wrong scaling of data in PSTricks plot

\DeclareSIUnit[mode = text]\kroner{kr.}

With the data above, the plot is as I want it but I've scaled the data manually from the original data;

\savedata{\data}[{0,9500},{10,9505},{20,9510},{30,9515},{40,9520},{50,9525},{100,9550},{500,9750},{1000,10000},{2000,10500},{3000,11000},{4000,11500},{5000,12000},{6000,12500},{7000,13000},{8000,13500},{9000,14000},{10000,14500},{11000,15000},{12000,15500},{13000,16000},{14000,16500},{15000,17000},{16000,17500}]


How do I change the code to get the same output with the original data?

\pstScalePoints(1,1){1000 div}{1000 div 7 sub}

• Thank you for the answer and sorry for not making the question minimal. When do I have to use \dataplot and when do I have to use \listplot? – Svend Tveskæg Oct 14 '14 at 16:51
• \dataplot uses internally the structure <val> D <val> D ... The PS function D can be used for internal data manipulation which is not often needed. listplot can this also by using \pstScalePoints – user2478 Oct 14 '14 at 16:58
