Trying to Plot cell array data
显示 更早的评论
So I have a dataset of music data that I am trying to correlate with information collected on the y axis. The data itself is a cell array containing a 2 element list in each index of the cell array, like this below.
1 2 3
[0.5,0.8] [1.3,2.4] [3.7, 6.1]
I want to plot this data as the x-axis against the information collected on the y axis, where between the two numbers in each list, it correlates to the value on the y-axis. This would look similar to a rectangular waveform.
Thanks
Mo

You lost me here:

I'm assuming the cell array is,
c = { [0.5,0.8], [1.3,2.4], [3.7, 6.1] };
Do you mean those are the x-coordinates?
What are the y coordinates?
What do you mean "Between the two numbers?
Correlation of what?

"What I am trying to do is create a sort of bar graph that has the left most point of the bar start at first value (0.5) in the list and the right most point of the bar end on the second value in the list of the cell array (0.8) and have their y value in that range be equal to 1 y-value which is why itd look like a bar. "
Bar plots have uniform widths but your bar widths aren't uniform so you cannot use bar().
Histograms can have different widths.
% c is a cell array of 1x2 vectors.
c = { [0.5,0.8], [1.3,2.4], [3.7, 6.1] };
% y is a cell array the same size as c containing scalar values
y = {2,3,4};
% Create plot
cla()
hold on % important
cellfun(@(edges,count)histogram('BinEdges',edges,'BinCounts',count),c,y)
