Dear community,
thank you for you support. I get now wonderful plots.
There is still a feature missing: Plot two has not x grid. *How to add
a grid without a axis?* (I tried a bit with newaxis... no success)
subplot(3, 1, 2)
co = color("blue");
plot2d(x1, y2, co);
b = gca();
b.font_color = co;
b.foreground = co;
*b.axes_visible(1) = "off"; xgrid(co, 1, 10)*
This code works well now:
subplot(3, 1, 3)
co=color("red");
plot2d(x1, y3, co);
xgrid(co, 1, 10)
c = gca();
c.font_color = co;
c.foreground = co;
c.data_bounds = [min(x1),min(y3); max(x1),max(y3)+(max(y3)-min(y3))*0.45]
//c.axes_visible(1) ="off";
ylabel(string(kT(y_3)),"color",co)
xlabel('Sekunden')
x= (A(:,1) - A(1,1)) * 24 * 3600;
//Input parameters for plotting the measurement numbers with optional gaps and
stacking to avoid overlapping
nstack=5;//maximum number of stacked measurement numbers
hstack=0.3;//height of measurement number stack (relative to window height)
ybase=max(y3)*1; //base ordinate for measurement numbers
yspan=max(y3)-min(y3);
plot(x1(M),y3(M), 'ko') // fügt schwarze dots hinzu
for m=1:length(M) //Beschriftung
xstring(x1(M(m)),ybase+(modulo(M(m),nstack))*hstack*yspan/nstack,string(M(m)))
set(handles.Anzeige, 'string', 'Diagrammbeschriftung' + string(k) + ' von' + string(A_size(1,1)))
end
If I have a few hours nothingelse to do, I will try to solve the prolbem withDenis sparse function. With out using a for loop, it will be faster.
Best regards
Frieder
PS: I wanted to send two plots, but they are 111kB. I plead for a higher limit.

Hallo Frieder,
If you insert
plot(x(M),y(M),'go') after//Writing measurement numbers
you get circle marks at the selected points to ease their correlation to
the measurement number.
Kind regards

Hallo Frieder,
You can independently combine stack and skip of the
measurement numbers by the code below.
//Plotting measurement numbers with optional gaps and optional stacking
to avoid overlapping
//Generating dummy measurement data x,y and plotting them
dx=0.5:50;// increment of x
x=cumsum(dx);
y=sind(x);
yspan=max(y)-min(y);
nM=length(x);//number of measurements
xdel();
plot(x,y,'r')
plot(x,y,'b+')
//Input parameters for plotting the measurement numbers with optional
gaps and stacking to avoid overlapping
nstack=6;//maximum number of stacked measurement numbers
hstack=0.1;//height of measurement number stack (relative to span).
hstack=0: no stacking independent of nstack
ybase=-1; //base ordinate for measurement numbers
step=2;// step=1: no gap, step=2: every second measurement number, etc.
//Writing measurement numbers
M=1:step:nM;//opted measurement numbers
for m=1:length(M)
xstring(x(M(m)),ybase+(modulo(M(m),nstack))*hstack*yspan/nstack,string(M(m)))
end
"How can I move the lettering above the plot (or at least to the bottom,
next to the x-axis)?"By data_bounds (see axes_properties in the help pages) you can
enlarge the y-axis beyond the y data span at will.The y-level of the lettering is
controlled by the input variable 'ybase' (see code above).
Kind regards
Jens

Hello everybody,
I did solve the Problem with showing only 10 line numbers,
by using IF.
printer=1
for k=1:A_size(1,1) //Beschriftung
*if k>A_size(1,1)*(printer/10) then*
printer = printer + 1
xstring(x(k),y3(1),string(k))
// xstring(x,y,str,[angle,[box]])
end
set(handles.Anzeige, 'string', 'Diagrammbeschriftung' + string(k) + ' von' + string(A_size(1,1)))
end
The line numbering is connected to the y-axis. How can I move the
lattering aboth the plot (or at least the bottom, next to the x-axis)?
(attached plot: subplot_with_line_number_2_tenth.gif)
About Jens help:
I attached three plots: the stacks Picture are with the Code of
Jens. Stacking is really nice, but I do not need every line number. With 921
data Points, it is already unreadable again. But thanks for your ideas, the
Code is great for learningn anyway.
Cheers

Hello Frieder,
Your plots look better now. You can avoid overlapping
of measurement numbers by sawtooth stacking them. See
example code below.
xdel();
//Generating dummy measurements x,y
dx=0.5:50;
x=cumsum(dx);
y=sind(x);
nM=length(x);//number of measurements
plot(x,y,'r')
plot(x,y,'b+')
//Plotting the measurement numbers in stacks to avoid
overlapping
nstack=6;//number of stacked measurement numbers
hstack=0.2;//height of measurement number stack (relative to
window height)
ybase=-0.9; //base ordinate for measurement numbers
yspan=max(y)-min(y);
for m=1:nM//measurement number
xstring(x(m),ybase+(modulo(m,nstack)-1)*hstack*yspan/nstack,string(m))
end
Kind regards
Jens

Hello,
thank you for all the feedback and help. It's
really great.
I used the idea of Jens Simon Strom combined with
some help from last week:
//Datensätze
x1 = (A(:,1) - A(1,1)) * 24 * 3600;
y1 = A(:,y_1);
y2 = A(:,y_2);
y3 = A(:,y_3);
drawlater()
subplot(3, 1, 1)
co = color("green");
plot2d(x1, y1, co);
a = gca();
b.font_color = co;
a.foreground = co;
ylabel(string(kT(y_1)),"color",co)
a.x_location = 'top';
subplot(3, 1, 2)
co = color("blue");
plot2d(x1, y2, co);
b = gca();
b.font_color = co;
b.foreground = co;
ylabel(string(kT(y_2)),"color",co)
b.axes_visible(1) = "off";
//b.marings = [0.1 0.1 0.3 0.5];
//b.filled ="off";
subplot(3, 1, 3)
co=color("red");
plot2d(x1, y3, co);
c = gca();
c.font_color = co;
c.foreground = co;
//c.axes_visible(1) ="off";
ylabel(string(kT(y_3)),"color",co)
//xlabel(string('Zeit [Sekunden]'), co)
x= (A(:,1) - A(1,1)) * 24 * 3600;
for k=1:A_size(1,1) //Beschriftung
xstring(x(k),x(1),string(k)) // x(1) always 0
// xstring(x,y,str,[angle,[box]])
disp(x(1))
end
//c.marings = [0.1 0.1 0.5 0.3];
//c.filled ="off";
drawnow()
The printed plots are attached. I did plot different
paramters, as I can choose then in my GUI.
That works well:
* Three plots, having the same x axis.
* x axis on the top and bottom
* Line *numbers Fitting the x axis*.
That does not work:
* showing a *few line numbers* only,
for reading (best case: Fitting the automatic
shown times in sec
Problem: I cannot tell, how many datapoints there
are going to be. So it mus be choosen automaticly.
Best regards

Hello,

Hi,
I was not able to follow the whole discussion
Neither did i,
but concerning your subplot challenge:
"/... I cannot add a second x-axis in a
subplot by newaxis(). How to add a x-axis
by using subplot?/"and your last example,
Couldn't you add a 4^th subplot at the
bottom in order to plot the 2^nd x-axis
(say by plotting only zeros)?
.
Why not using drawaxis() as already suggested?
drawaxis() is made for this kind of situation.
In this thread, no logarithmic axis is
involved. So i do to catch the reason of
ignoring drawaxis().
By the way, IMO, a drawing of what exactly is
required would be clearer than hundred of
lines of description, with schematic curves,
axes, arrows linking curves to their multiple
axes in x and y.
