13.2.6. Macro “dataserverLoadASCIIFileIonosphere.C”

13.2.6.1. Objective

The objective of this macro is to load the ASCII data file ionosphere.dat which defines 34 input variables and one output variable y and applies visualisation on one of these variables. The data file ionosphere.dat is in the “Salome-table” format of Uranie but is not shown for convenience.

    TDataServer * tds = new TDataServer();

    TCanvas  *Canvas = new TCanvas("c1", "Graph for the Macro loadASCIIFileIonosphere",5,64,1270,667);

    tds->fileDataRead("ionosphere.dat");

    tds->getAttribute("x28")->SetTitle("#Delta P_{e}^{F_{iso}}");

    // Graph
    tds->draw("x28");

The TDataServer is filled with ionosphere.dat with the fileDataRead method

    tds->fileDataRead("ionosphere.dat");

A new title is set for the variable x28

    tds->getAttribute("x28")->SetTitle("#Delta P_{e}^{F_{iso}}");

This variable is then drawn with its new title

    tds->draw("x28");
