2D plot array elements
显示 更早的评论
I'm trying to plot elements from an array of solutions (value of percentage), against a changing parameter ABP. However I only get an empty figure.
valueofPercentage= [1 ... n] ABP=[1 ... n] , where n corresponds to 200 elements.
This is the code:
for s=1:1:200
ABP(P_a_b)=s;
end
for n=length(valueofCBF)
percentage= ((valueofCBF(:,1) - CBF_base)/ CBF_base)*100
valueofPercentage(n)=percentage;
end
for a=length(ABP)
figure(1)
hold on;
plot(ABP(a,:),valueofPercentage(a,:))
end
hold off;

What is P_a_b? You did not define valueofCBF. You did not define CBF_base. This code is wrong. Correct them.

You wrote for n=length(valueofCBF), usually that's an error and people mean for n= 1: length(valueofCBF). Same goes for the other for-loop.
There is a more fundamental problem: you are plotting a single value (ABP(a)) against a vector (valueofPercentage). This will result in an error.
Also, you should pre-allocate the vector valueofPercentage.

Why don't you use plot(ABP,valueCBF) then? If you want to plot individual points one by one, make sure to include a hold on after the first plot and using a format for plot that shows points, like plot(ABP(a),valueCBF(a),'*')
