Hello,
I wish to put 2D curve fitting to different axis within a 3D plot. I am attaching an image for reference.
representational image on this actual data set Actual Data set
As you can see the curve fitting for x and y axis is at z=0 value, i need that at say z=10 or 20.
Further when I try to do curve fitting for x and z data set or y and z data set, the fitted curve instead of appearing on the the X-Z plane or Y-Z plane, is appearing on the X-Y plane.
All help is appreciated.

Hello,
I found a workaround using the polyfit function. Hope this helps others. Still trying to figure out how to extend the polyfit lines beyond the data points, will get there eventually.
% Curve Fitting for HS6-5-3 PM
[xData9, yData9, zData9] = prepareCurveData( Cycles_HS6_PM, SqRt_Area_HS6_PM, Tension_HS6_PM );
%Fit model to data.
y=0+zeros(42,1);
z = Tension_HS6_PM
p = polyfit(zData9, xData9,1);
x = polyval(p,z);
h=plot3(x,y,z)
h.Color = '#9475EB'; % Indigo
T = table(x,y,z,'VariableNames',{'X','Y','Z'})
%Fit model to data.
z=400+zeros(42,1);
x = Cycles_HS6_PM
p = polyfit(xData9, yData9,1);
y = polyval(p,x);
h=plot3(x,y,z)
h.Color = '#9475EB'; % Indigo
T = table(x,y,z,'VariableNames',{'X','Y','Z'})
