Problems with legend in R2016b

Why can I no longer add a plot with a legend in R2016b same way it used to be in previews versions?

During the migration to R2016b or R2017a, the script show some problems with legend function in the plot.

An example is a simple line after a plot: legend('Curve1','Curve2',1);

While it used to work fine prior to R2016b, we see the following response :

Error using legend>process_inputs (line 582) Invalid argument. Type 'help legend' for more information.

Error in legend>make_legend (line 340) [autoupdate,orient,location,position,children,listen,strings,propargs] = process_inputs(ha,argin); %#ok

Error in legend (line 294) make_legend(ha,args(arg:end),version);

Error in Script_plot (line 274) legend('Curve1','Curve2',1);

The numeric location designations have been deprecated. Use the 'Location' name-value pair instead:

legend('Curve1','Curve2', 'Location','NE')

This solution doesn't work for me (2017a). Any other solution for this problem?

[Walter Roberson]

   plot(1:10,rand(1,10),1:10,rand(1,10)); legend('Curve1','Curve2', 'Location','NE')

Looks fine to me in R2017a.

Hello,

The problem is not really how to add a legend anymore. We can read it thru Strider's answer, thanks, but also on the help. The question is more how to make sure our older Script to work on R2017a without changing each of the legend lines.

Thanks in advance,

You have to go back and manually change all the legend calls in your old code.

[Walter Roberson]

Write your own legend.m function that you put higher in the priority and which detects the use of the old style calls and converts the arguments and calls the built-in legend
