Hi,

Im using the candle matlab function to produce a candlestick chart on stock data. I would also like to plot other analysis data such as moving average, but how do i put it on the same axes? Ive worked out the moving average fine but the matlab function controls the code for producing the graph, and cant seem to find a way of adding other data even though the x-values are the same. Can you help?

Many Thanks Tom

在 MATLAB Online 中打开

%make first chart  
hold on 
%make second chart

hold on retains the current plot and certain axes properties so that subsequent graphing commands add to the existing graph.

Hey ye this is a very neat solution, however when i try to cut the data series down to say 50 days for plotting I keep getting problems with 'CAT arguments dimensions are not consistent'. I think the problem lies in the fact that the cnadle function plots the weekends for which there is no stock data, so when you add a moving average for the same time period without the weekends the axis will not line up. Do you have a solution for selecting a specific length of data to plot from yahoos spreadsheets?
