Dear Jens, ```
```
yes, the plot_date_16_lines.gif Show real data, but
only a few lines of it.

For two reasons, showing the datevec isn't a
datenumber, solved the Problem to have a readalbe time. I use a first
diagramm for choosing the intervall I am going to process later on. For
the choosing of the time period, I have two butooms that Show two
different Diagramms. The first shows the entire time period and the
scound enlargest the choosen period of time.

I choose the period by
tiping the start and finish line number in my gui. With the secounds
printed, I do not know the line number. So I have to try and print and
try and print. ...

Why aren't the secounds the same as the line number
(data Point)?

Because my data Looks like this:

Zeit Distanz
Geschwindigkeit 1 Drehzahl Cv-Druck Richtung Lokbremse anlegen Lokbremse
lösen Zugbremse anlegen Zugbremse lösen Kupplung betätigt Bremsen aktiv

03.04.2012 08:49:20.090 46476.4940 0.00 478.61 0.53 0 0 0 1 0 0 0

Translate the header: time distance Speed Revolution Speed, ....

The
time period between each data Point isn't the same. Once the locomotive
starts to operate, the programm does print line by line, each time a
paramter changes. If the locomotive stands a few hours around, the data
has a gap.

But I want to print on one x axis the time in Secounds (or
maybe hours or days, depends on the period I have to process). On the
secound x-axis, I want to print the line number. On the attached
Diagramm, you see that there is a gap between secound 2000 and secound
3500. That one must to be seen in the Diagramm, but I want to know what
line is secound 2000 and what line is secound 3500, to maybe chosse the
time of Operation of the locomotive before These night break.

The
question of datapoints is: They differ between a few tousand (50 000)
and a few millions. The Programm must be able to operate with booth. The
first Diagramm is going to Show me the entire time period of a few days.
Then I have a secound Diagramm. With the secound one, I choose by tiping
the start and finsih line number in my gui, the time period of my
Diagramm. Maybe one day. Then I have the data a Little big bigger, then
I do choose the hours of interet. That might be just one hour. Then I do
type the lines of this time period.

In the end, I do print the choosen
time period in a new document, adding (calculating) a few more parametre
like traction. With the printed document, is for Simulation.

My
approach now is. Plotting three Diagramm abooth each other. But I cannot
ad a secound x-axis in a subplot by newaxis(). How to add a x-axis by
using subplot?

thanks for you help. I tried to adopt your Code to my programm. No
success. There is a prolbem I should have metioned eralier. The time
between each datapoint has a different time period. So I cant print the
y-axis over the time and add a a secound x axis for the line of
document. I might stick to the plotxyyy. Best regards Frieder Am

>>> Dear Frieder, one
more comment. Instead of using "foo"-data, it might be more useful to
plot each graph several times. Otherwise the y-axes are not assosiated
with the data and you have to take more care about them. e.g.: //
display all graph on first x-axis plot2d(x1,y1); // and hide the y1-axis
plot2d(x1,y2); // and hide the y2-axis plot2d(x1,y3); // and hide the

possible to draw only an axis without showing the corresponding data.
Hence: One can create some "fake" or "foo" data not displaying them, but
showing the corresponding axis. so using this principle, you can draw as
many axes as you like..and place them where you like. clc(); clear(all);
// all datashare same x axis // example: there are 1000 datapoints x1 =
linspace(1,1000,1000); // each graph has its own y-axis y1 = x1; y2 =
200*sin(1/20 * x1); y3 = sqrt(x1); // create fake x-values for y-axis
fake_x = zeros(1,length(x1)); y1_min = 0; // min-value for y1-axis
y1_max = 100; // max value for y1 axis y2_min = -2; // min-value for
y2-axis y2_max = 2; // max value for y2 axis y3_min = 10; // min-value
for y3-axis y3_max = 20; // max value for y3 axis // create 2nd x-axis
// example: the 1000 datapoints has been taken in 60 seconds x2_min = 0;

You just divide the (numerical) time interval into an adequate number of
points (which can be neatly accommodated) with linspace or : and plot
the corresponding time text colums via a for-loop. There is no need that
text times coincide with measured data. They only should be placed at
the correct locations. 3:You may not be familiar with how to get quick
help from Scilab: Just highlight the command plot2d or style here and go
to the help pages BY RIGHT MOUSE CLICK. 4: Highlight newaxes, foreground
5: I would postpone integrating a checkbox until everything else is to
your satisfaction. The rest of #5 is perhaps answered by #1. General
remarks * Do not ask many questions simultaneously. Attack them one by
one. You make it easier for yourself and the helpers. * Accompany your
questions by short examples which omit irrelevant ornaments. The code
you really write with the variables you really use is less appropriate
in most cases. * Begin to polish the results (color, line types, fonts,
fontsize, etc.) only as the last step in your work. At the beginning
accept what Scilab delivers to you. * Work the help pages. My painful
experience is that the polishing job often consumes more time (and
nerves) than the technical problem itself. Scilab is far from intuitive
in that respect. Kind regards, Jens
