Dear Users of the Forum,
Im new here, and due to the lack of a subject, the website deleted by POSTDATA before sending it. So I write again, but shorter:
I draw a measurement graph, where I find two X-values for given Y-values. Now I need their "delta". I can draw vertical lines at given x-values, but I don't succeed in drawing them at the positions of my "found-out" x-values. Do I have to assign them somehow?
How can I achieve to know these values, to subtract one of the other and to print them into a box into the graph?
I find out these values with this short script:
xaty01 = table( %c, xof(%c), 0.1 );
xaty09 = table( %c, xof(%c), 0.9 );
ixaty01 = xindex( xaty01, %c );
ixaty09 = xindex( xaty09, %c );
mks1 = ixaty01;
mks2 = ixaty09;
I found it on the forum. But the following command doesn't work:
draw -lm -v ixaty01;
Many many thanks in advance,
Timmi_N

O.K., I found out that
A=[value];
assigns a value and that
A=;
types it out.
But why can't I assign a "found out" value like this, subtract it and plot a line there?

Hi Timmi_N,
The draw -l -v command takes an x-value as an argument, not an index. Try this...
draw -l -v xaty01;
I wasn't aware of the -lm option but it seems to work too.

Hello Mike!
Thanks a lot, your tip has exactly solved my problem. I didn' understand that the "i" in front of the variable name means the use of an "index", neither I found anything about in the help.
Bye,
Tim

Hi Tim,quote:

It has nothing to do with the variable name. The xindex command returns a row number so you've defined ixaty01 as an index.
