Problem with candle chart and loop

Hello community,

I have a problem with creating a candle chart from a matrix using a for loop.

Just for comparison: I can make a loop for a simple plot (x,y) like this:

for z=1:length(x)

plot(x(1,z),y(1,z),'+r') hold on

end

In this case every point follows each other in the chart and everything is fine.

But when I want to use this simple method with candle() instead of plot(), it just overrides this first candle (data set) in the chart and I get a stack of overlapping candles.

for f=1:length(date)

    candle(open(f,4),high(f,3),low(f,5),close(f,2),'b')
    hold on

end

Does anybody know how to solve this problem? Would be very nice!

Merry Christmas and thanks, Dominik

In the version using plot(), you are telling MATLAB to place the plot marker at different x locations, but in the version using candle(), you are not specifying different dates to place the plot markers, so they just overlap. You need to use the 6-argument version of candle(), something like

candle(open(f,4),high(f,3),low(f,5),close(f,2),'b',date(f),Dateform)

as described in the documentation:

doc candle

I don't have the Finance Toolbox, so I may not have that quite right, but I think that is the gist of your problem.
