<p>Hello Daniel,</p>
<p>There can be different answers depending on what you are trying
to obtain at the end. <br>
</p>
<p>Do you need to smooth curves by themselves, or are you somewhat
trying to build a smooth surface based on iso-value curves (your
TORQUE X SPEED curve ?) ?<br>
</p>
<p> In this latter case, can you provide the efficiency value
associated to each TORQUE X SPEED curve ?</p>
<p>In the former case, you need some ordering of your data, e.g. by
angle computed with center located at the mass center of points,
then least squares splines could be applied more efficiently.<br>
</p>
<p>S.<br>

<div dir="ltr">Dear friends, I'm still a layman at SCILAB, but I'm
using SCILAB this week to be able to plot an efficiency map
through a routine I created on it. Basically the efficiency map
is summarized in<b> annex 1_0 and annex 1_1</b>(I took it from
the internet to exemplify the problem), where through a TORQUE X
SPEED curve I have efficiency lines.<br>
In <b>annex 2</b>, I have an example of how my curve looks so
far. Based on the example, I have two problems:<br>
1) I tried to use the SPLIN function to interpolate the points,
but it doesn't work considering that it works only with strictly
increasing vectors. Any suggestions for me to smooth the curve?<br>
2) When trying to add colors, I realized that most plotting
functions do not work with values that are not real, which is my
case ... All values with decimal places. Any suggestions for
solving this other problem?
<div><br>
Friends, I appreciate any form of help...</div>
