<br>
Thanks for pointing this issue.<br>
It is clearly a bug. It occurs since the earliest ages of Scilab.<br>
It will be fixed ASAP.<br>

<br>
I know it is better to use plot2d, but I wonder why plot works
differently from plot2d when one of the variables is integer.<br>
<br>
Consider this code<br>
<br>
// Generate x axis with real (double) numbers<br>
x = (1:20)/20<br>
<br>
// Generate y axis with random integers<br>
y = iconvert(100*rand(1,20),2)<br>
<br>
// Plot y vs x<br>
plot(x, y)<br>
<br>
The plot represents x vs its index, which is not the intended
behavior. Replacing plot(x,y) with plot2d(x,y) we get the
correct plot.<br>
<br>
The documentation of both plot and plot2d requires "real" matrix
or vector. It seems that plot takes it a bit too literally (as a
data type) while plot2d adheres to the mathematical meaning of
"real" (considering integer numbers as a subset of real
numbers).<br>
<br>
Is there a fundamental reason for this?<br>
<br>
The problem arises when one retrieves integers from a file
without converting them to double (which requires much more
memory).<br>
<br>
