The SCI file is the following one:
// Reading the txt file---------------------------------------------------------
y=read("C:\...path...\Essai_scilab.txt",31,2)
//31 = number of rows
//2 = number of columns
//Ploting the results-----------------------------------------------------------
clf;
plot(y(:,1),y(:,2),'thickness',2);
xgrid(2,1,8);
xlabel('1st column data');xlabel color blue fontsize 3;//Define x axis
ylabel('2nd column data');ylabel color blue fontsize 3;//Define y axis
title("Reading a text file");title color peru background grey90 fontsize 5;
gcf().background=color('gray');//Set the background color of the figure
gca().background=color('gray85');//Set the background color of the plotting area
// colors names are coming from Color_list in SCILAB help browser
