MATLAB: Update candle plot with additional candle

candleFinancial Toolbox

Is it somehow possible to update an existing candle-plot without redrawing the whole chart?

Meaning I want to add a candle when new data has arrived. Everytime redrawing the whole chart is rather slow.

If you save the handle to the plot, you can access its Data property

h = candle(ax, someData)
h.Data(end+1) = [1 2 3 4];

Something like that:

load disney.mat
candle(dis('3/31/98::4/30/98'))
title('Disney 3/31/98 to 4/30/98')
ch = get(gca,'children');
set(ch(1),'FaceColor','r')
set(ch(2),'FaceColor','g')

Your question is ill-defined:

You have not presented enough info.

1. Is the middle column the noisy signal?

2. Is the noise supposed to be

 a. additive?
 b. zero-mean?
 c. constant variance?
 d. Gaussian distributed?

If so, how was the variance measured? In particular, how many points were used to estimate each tabulated value?
