MATLAB: Can’t I see the top legend on a Financial Time Series plot created by FTSGUI

Financial Time Series Toolboxfintsftsguilegendplot

Why can't I see the top legend on a Financial Time Series plot created by FTSGUI?

Upon loading a Financial Time Series through FTSGUI, the legend for the top plot which contains opening, closing, high, and low information is not visible. The legend for the bottom plot which contains volume information is visible.

This problem is caused by the creation of the axes children in the first figure window for a particular time series. Specifically, the legend is created, but is hidden behind the top axis.

This problem only occurs in the first displayed window for the time series; others have their legends displayed properly.

Best Answer

This problem has been fixed in Financial Time Series Toolbox 2.0 (R13).

If you are using a previous version, please read the following:

This problem is caused by incorrectly making the axes current in the fints overloaded method for the PLOT function.

To correct the problem:

1. Type 'edit fints/plot' at the MATLAB prompt. This should open it up in the Editor.

2. Change lines 104 and 164 to:

set(gcf, 'currentaxes', hsub1);

This will display the legend properly.

MATLAB: Do I receive an error when I try to connect to the Bloomberg database using the BLOOMBERG function

The documentation has been updated in Release 2008a (R2008a). For previous product releases, read below:

You may encounter this error if the 'bbapi.dll' file is not found on the system path or if 'bbcomm.exe' is not running.

1. You can verify if the Bloomberg API is working by going to the 'Windows Start' menu and choosing "Bloomberg -> API Demo".    
2. You will need to verify that 'bbapi.dll' is on your Windows system path ( system environment variable - PATH) to work with MATLAB. To check this, visit the following support article from Microsoft. 
 <http://support.microsoft.com/kb/310519>

Another possibility is that the user is not using the right syntax. The two input form is no longer supported by Bloomberg. So to connect, you can try:

>> c = bloomberg

Alternatively:

The Bloomberg software is updated regularly and only the most recent version of the Datafeed Toolbox may contain the correct library interface to connect with the Bloomberg API.

The only workaround is to update the version of MATLAB which is being used.

Also, this error may occur because too many connections to the Bloomberg data server have already been established. This may be the result of calling the command

c = bloomberg;

in a FOR-loop. In this case, you should either close the bloomberg connection:

close(c);

before the next iteration or, ideally, open the connection outside of the FOR-loop and use only that one connection within the loop.

MATLAB: Do I get an error while plotting a Financial Time Series which includes a NaN input in the Financial Time Series Toolbox

This is a bug in the Financial Time Series Toolbox v1.1 (R12.1) that has been fixed in the Financial Time Series Toolbox 2.0 (R13).

If you are still using version 1.1 of the Toolbox, one workaround, would be to not plot financial time series with a plotting option.

As a secondary workaround, you can add the following code between lines 172 and 173 of MATLAB_ROOT\toolbox\ftseries\@fints\plot.m:

else,
     ftsa_plotdata = ftsa_data(:, :);
     plot_legend = ftsa.names(4:end);

This seems to solve the problem as well.
