Hey People,
im trying to implement a multiple live plot function for my data. Instead of long description, here some code for understanding:
Main:
while plotting == true
for i=0:0.05:10
x = sin(i);
Input.Value(1,1) = i;
Input.Value(1,2) = x;
y = cos(i);
Input.Value(2,1) = i;
Input.Value(2,2) = y;
plotting = Liveplot(Input);
end
end
and the Liveplot function:
function [Running] = Liveplot(Input)
for i=1:size(Input.Value,1)
figure(i);
hold on;
plot(Input.Value(i,1),Input.Value(i,2));
drawnow;
hold off;
end
end
(sure some code between is missing, hope you understand my thinking)
I want a line between my parameters - a graph, interpolation, ... and not only points at the plot (see image below)
If i dont tell my plot to make '+', i dont see any points at the plot.
How can i see my graph of the datapoints (the line between)?
(at picture both functions in one plot...)

if you change your code to the following code
clear all
close all
clc
count=1
In.Value(1,1) = 0;
In.Value(2,1) = 0;
for i=0:2*pi/100:2*pi
x = sin(i);
y = cos(i);
In1.Value(1,count) = i;
In1.Value(2,count) = x;
In2.Value(1,count) = i;
In2.Value(2,count) = y;
count=count+1
end
Liveplot(In1)
hold on
Liveplot(In2)
and overload your plot function like this.
function Liveplot(In)
plot(In.Value(1,:),In.Value(2,:),'b-')
end

Then i dont have the option to see my plot in time while simulating. Im trying to write a liveplot function

change in your liveplot function
plot(Input.Value(i-1:1,1),Input.Value(i-1:i,2),'-b');
so your code create a line and not a point.
