Re: [Scilab-users] Filled polygons from polylines

Think I spotted it...

figure(1), clf

f=gcf();
f.figure_size=[1024,800];
f.figure_name = "Subsidence of the Kufrah Basin Well A1-NC198";
f.background=8 // white background


title ('Subsidence of the Kufrah Basin Well A1-NC198') // Figure title

subplot (2,1,1)

a=gca();
a.font_size=3

[f,epoly,ey1,ey2]=BetweenCurves(-t,-xu(2,1:n),-xu(3,1:n),'Handle',f,'axis',a,
'foreground', 12 ) // for each interval

plot (-t,-xu(2,1:n),'b-o',..
  -t,-xu(3,1:n),'b-o',..
  -t,-xu(4,1:n),'b-o',.. etc

Re: [Scilab-users] Filled polygons from polylines

2021-04-07 Thread arctica1963 
Hello Antoine,

Your code does seem to work since the x locations are constant for each
curve. However, I cannot see where exactly to apply the code for each layer
within my existing code and how to apply different fill colours.

This works to fill between the 2nd and 3rd polylines (see image):
[epoly,ey1,ey2]=BetweenCurves(-t,-xu(2,1:n),-xu(3,1:n)) // x=time,
y=subsidence

Sure it is something to do with the figure (f) and axes (a) handles.

Could you clarify where things go.

Many thanks

Lester

Re: [Scilab-users] Filled polygons from polylines

2021-04-07 Thread CRETE Denis 
Hello, I did not look carefully at the function "BetweenCurves", but it 
requires y1 and y2 to share the same x data. Isn't it a limitation ? Would it 
be useful to extend it to the case where x1 and x2 are not identical ?
Best regards
Denis

Hello all,

I think I answered this question before on this mailing list...

Ah, yes I did:

http://mailinglists.scilab.org/Reg-Area-Between-two-curves-td3393261.html#a4026721

Get the source for "[h,epoly,ey1,ey2]=BetweenCurves(x,y1,y2,varargin)" 
in the thread.

Hope it helps,

Antoine

Objet : [Scilab-users] Filled polygons from polylines

Hello,

I have script that reads a csv file containing the data and uses that to 
calculate subsidence from well information. This all works fine, but it is not 
the best way to display the result. Is it possible to take the polyline output 
and generate filled polygons (similar to attached image)?

I am not sure how it is possible from the existing code to close the output 
result used in the plot function to create a closed polygon. Essentially it 
needs extra points otherwise you would just tie the end point and start point 
of the polyline.

It would be good to get some other ideas and whether it is actually possible. 
Original code was in Matlab and had all of the data within the script, so I 
took that out and stored in a separate data file for ease of use.

Thanks for any suggestions.
