Hello!!!

I hope you can help me with this difficulty.

I have been trying to assign the Excel-exported matlab series date vector as the X axis tick labels. I am using a script to import a price data and then plot this data with the help of the CANDLE function. I try to plot a few more lines onto this chart. And have the original price series data to be used as the X axis label vector. I have two outcomes of this process:

1) I plot both the prices using the CANDLE function (using the CANDLE(HI, LO, CL, OP ) format) and the additional lines – FINE, except that the lower axis shows the usual integers in the ascending order – from 0 to 1000.

Code used:

candle(Num(7:end2,3),Num(7:end2,4),Num(7:end2,5),Num(7:end2,2),'k');

2) I plot the prices using the CANDLE function ( in the CANDLE(HI, LO, CL, OP, COLOR, DATES, DATEFORM) format, in which the DATES are the serial vector of the dates exported from Excel and converted into the Matlab format) BUT I cannot plot the rest of the lines over this chart. It shows only the candles…..

Code used:

candle(Num(7:end2,3),Num(7:end2,4),Num(7:end2,5),Num(7:end2,2),'k',matlabdate,'mmmyy');

I have not been able to “marry” the CANDLE(HI, LO, CL, OP, COLOR, DATES, DATEFORM) function with the usual LINE plots – the lines just refuse to plot over the candlestick charts with the dates on the x axis…I am not sure why….maybe this is because in this case the X axis starts at the serial dates much larger than the 0 origin used in with CANDLE(HI, LO, CL, OP ) format?

I also thought if it might be possible to use just the CANDLE(HI, LO, CL, OP ) format and then simply assign the labels over the x axis based on the MATLABDATE Date series vector?

I tried this with:

a=gca;
xtick=get(a,'xtick');
xticklabel=datestr(matlabdate,'yyyy/mm/dd');
set(a,'xticklabel',xticklabel);

And it does not seem to work…

I also used the

% dateaxis('x', 12, startdstr);

And it does not seem to work as well as it does not match the dates exported from the Excel….lagging the originals….

I hope you can help me with this problem. I need to ensure that the candlestick plots display the candles at the exactly the same times that are exported from excel and that the lines show up on this date-labeled chart as well. I hope this is possible

I will be happy to hear any opinion!!

Thank you for your time!)
