Financial Toolbox

High-Low-Close Chart Example

First load the data and set up matrix dimensions. load and size are standard MATLAB functions.

• load ibm.dat;
  [ro, co] = size(ibm);
  

Open a figure window for the chart. Use the Financial Toolbox highlow function to plot high, low, and close prices for the last 50 trading days in the data file.

• figure;
  highlow(ibm(ro-50:ro,2),ibm(ro-50:ro,3),ibm(ro-50:ro,4),[],'b');
  

Add labels and title, and set axes with standard MATLAB functions. Use the Financial Toolbox dateaxis function to provide dates for the x-axis ticks.

• xlabel('');
  ylabel('Price ($)');
  title('International Business Machines, 941231 - 950219');
  axis([0 50 -inf inf]);
  dateaxis('x',6,'31-Dec-1994')
  

MATLAB produces a figure similar to this. The plotted data and axes you see may differ. Viewed online, the high-low-close bars are blue.
