Hello,
I have a bar plot that shows the value for each fluid type but I want the bar to be green if the value of the bar is larger than 0.7. The simplified code is as follows:
neworder = {
'Hot Water' [0.2700]
'Steamflood' [0.4500]
'N2' [0.6800]
'CO2' [1.0100]
'HC' [1.0100]};
for i=1:length(neworder)
if cell2mat(neworder(i,2))<0.7
neworder1(i,:)=neworder(i,:);
else
neworder2(i,:)=neworder(i,:);
end
end
figure
barh([neworder1{:,2}],0.5,'b');
set(gca,'YtickL',neworder1(:,1),...
'XLim',[0 1],...
'Color','white');
hold on
barh([neworder2{:,2}],0.5,'g');
set(gca,'YtickL',neworder2(:,1),...
'XLim',[0 1],...
'Color','white');
This code puts two values on the same plots as I wanted but some of the values disappear. What I want is I want to see 5 bars 3 of which are blue and the rest two are green.
Thank you very much in advance.

Study this and note especially the length and values of neworder, neworder1 and neworder2 in your and my revised code.
function cssm()
neworder = {
'Hot Water' [0.2700]
'Steamflood' [0.4500]
'N2' [0.6800]
'CO2' [1.0100]
'HC' [1.0100]};
y_labels = neworder( :, 1 );
neworder1 = cat( 2, y_labels, num2cell( nan(5,1) ) );
neworder2 = cat( 2, y_labels, num2cell( nan(5,1) ) );
for i=1:length(neworder)
if cell2mat(neworder(i,2))<0.7
neworder1(i,:)=neworder(i,:);
else
neworder2(i,:)=neworder(i,:);
end
end
figure
barh([neworder1{:,2}],0.5,'b');
set(gca,'YtickL',neworder1(:,1),...
'XLim',[0 1],...
'Color','white');
hold on
barh([neworder2{:,2}],0.5,'g');
set(gca,'YtickL',neworder2(:,1),...
'XLim',[0 1],...
'Color','white');
end
I've included "%%" for a purpose. They make it possible to run one cell at a time and inspect the result. There are buttons, "Evaluate Cell ..."
