I need to draw a circle over a polar plot in labview 7.1. How do I do that? (A step by step guide will be appreciated) I've found the circle drawing function, but am having problems with its input, especially that pixel centre one. Thanks

I am a complete beginer to Labview and am trying to use polar plots in labview. The problem is that I can't input a function into the polar plot (i am trying to modify the polar plot demo that came with labview examples). The demo has a random function as an input. So my question is that how do i input a function and it runs/animates for some time? A function like Sin (2*pi*t) where t is a variable with values from, say, 1 to 100. So that some sort of animation can be observed on the polar plot. THanks

Hello there, Sorry for the odd first post but am really desperate here. Can anybody please convert the following matlab code to labview? It will be a big help. clear; colordef white;p=input('How many poles '); % No. of polestheta=linspace(0,2*pi,50); n=length(theta);ro=6; rs=5; rr=4; % Outside, bore, & rotor radiirgr=4.5; % Air gap center grid radiusRo=ro*ones(1,n);Rs=rs*ones(1,n);Rgr=rgr*ones(1,n);Rr=rr*ones(1,n);F=zeros(1,n); F1=F; F2=F; phi=pi/4;for i=1:37; pause(0.001); polar(theta,Ro,'-.'); hold on; polar(theta,Rs,'-.'); polar(theta,Rgr,'m'); polar(theta,Rr,'g-.');for j=1:n; F1(j)=Rr(j)+0.5+0.225*cos(p/2*theta(j)-phi);F2(j)=Rr(j)+0.5+0.225*cos(p/2*theta(j)+phi);F(j)=F1(j)+F2(j)-Rr(j)-0.5; endpolar(theta,F,'r'); polar(theta,F1,'y:'); polar(theta,F2,'c-.');text(0.9,rs+0.25,'Stator');text(-1.5,rr-0.75,'Rotor');text(5.5,5,'.. Forward');text(5.5,4,'-. Backward');text(5.5,6,'- Resultant');name=['Air gap mmf waves of single-phase induction motor'; ' '; ' ']; title(name);phi=phi+pi/18; hold off;end Any help will be appreciated Thanks alot
