The following code with mphplot(model,'pg1') plots 2 lines in a figure properly but doesn't show the legend. What's the problem?

model.result.create('pg1', 'PlotGroup1D'); model.result('pg1').create('lngr1', 'LineGraph'); model.result('pg1').feature('lngr1').set('xdata', 'expr'); model.result('pg1').feature('lngr1').selection.set([1]);

model.result('pg1').set('looplevelinput', {'manual'}); model.result('pg1').set('looplevel', {'1, 101'}); model.result('pg1').set('xlabel', 'x-coordinate (m)'); model.result('pg1').set('ylabel', 'Dependent variable u (1)'); model.result('pg1').set('legendpos', 'lowermiddle'); model.result('pg1').set('xlabelactive', false); model.result('pg1').set('ylabelactive', false); model.result('pg1').feature('lngr1').label('Line Graph'); model.result('pg1').feature('lngr1').set('xdataexpr', 'x'); model.result('pg1').feature('lngr1').set('xdataunit', 'm'); model.result('pg1').feature('lngr1').set('xdatadescr', 'x-coordinate'); model.result('pg1').feature('lngr1').set('linemarker', 'point'); model.result('pg1').feature('lngr1').set('markerpos', 'datapoints'); model.result('pg1').feature('lngr1').set('legend', true); model.result('pg1').feature('lngr1').set('resolution', 'norefine');

Discussion Forum Rules and Guidelines

The goal of COMSOL Access is to provide a forum for you to communicate effectively with COMSOL as well as your colleagues within the multiphysics simulation community. This involves providing you with access to technical support and downloads of the latest {:comsol} software releases, as well as the ability to share your comments and work with other users of the {:comsol} software through forums such as the blog, discussion forum, and Application Exchange. In order to make this an efficient and pleasant experience for you and other members of COMSOL Access, we ask that you follow a few rules and guidelines.

You agree that you will not otherwise use your COMSOL Access account to violate or to assist anyone in violating any law. Engaging in any activity in violation of these COMSOL Access rules and guidelines may lead to you being immediately and permanently banned from COMSOL Access.

Basic Rules

Flaming: Do not post any messages that harass, insult, belittle, threaten, or flame another member or guest. Debates are fine, but argue with the point, not the person.
Trolling: Do not post with the purpose of starting a dispute. Note that a person disagreeing with your opinion is not considered trolling; keep it civil, even if you are sure that the other person is wrong. Anything seen as trolling will result in you being banned.
Spamming: Posts without content or containing nonsense waste space and everyone's time. Spam will be removed from the forum.
Offensive Posts, Links or Images: Do not use profanity, racial, ethnic, religious, or other slurs or any other offensive material.
Advertising: Posting of advertisements for products or services, links to auctions, affiliate links, links to promote websites, and so forth is not allowed.
Disclosure of Personal Information: Do not disclose any other member's email, real name, address, phone number, IP address, or other personal information. This includes posting contents of emails and private messages without the sender's consent. Do not bring personal disputes into the forums. Bans and warnings issued to other users are considered personal information.
Misleading Titles: The subject line of the post should be as informative as possible about the content of the post. This also reduces the amount of duplicate posts.
Thread Hijacking: Taking a thread off-topic to pursue one's own agenda is not permitted.
Piracy: Do not upload, post, email, transmit, or otherwise make available any content that infringes upon any patent, trademark, trade secret, copyright, or other proprietary rights ("Rights") of any party. This includes COMSOL model files created by a forged or illegitimate license.
Honesty: Users must provide truthful information in creating their COMSOL Access account.

These rules are subject to change. The moderators reserve the right to remove, edit, or move posts at their discretion. The COMSOL Access administrators will reserve the right to permanently remove a user account without notice if any of the rules are not followed. Particular services accessible with your COMSOL Access account may be subject to additional rules. You agree to comply with all rules applicable to each service you access through your COMSOL Access account.

Posting Guidelines

When posting, understand that you are trying to communicate with other people. Although many COMSOL Access members are not fluent in English, the official language of this forum is English.

Here are some important guidelines of language:

Write in English.
If you are familiar with LaTeX, please use this to write mathematical equations.
Always do a quick check for spelling/grammar mistakes.
Format your post in a legible manner. Use the Preview button often.
Be concise and articulate as much as possible.
Use the Enter key to create paragraphs.
Capitalize correctly. It is difficult to read posts that are written entirely in uppercase or lowercase.
Use correct punctuation. Avoid run-on sentences.
Try to avoid using “text speak”, “net speak”, or slang. The purpose of language is to be understood.
Never invent acronyms and use as few acronyms as possible. For example, write "COMSOL Multiphysics" and not "CMP".
Review your post before publishing it. Try to catch typos.
Please check to see if a topic has already been posted. Do not post multiple threads on the same topic.
