-# Security Guide
-
-Open MCT is a rich client with plugin support that executes as a single page
-web application in a browser environment. Security concerns and
-vulnerabilities associated with the web as a platform should be considered
-before deploying Open MCT (or any other web application) for mission or
-production usage.
-
-This document describes several important points to consider when developing
-for or deploying Open MCT securely. Other resources such as
-[Open Web Application Security Project (OWASP)](https://www.owasp.org)
-provide a deeper and more general overview of security for web applications.
-
-
-## Security Model
-
-Open MCT has been architected assuming the following deployment pattern:
-
-* A tagged, tested Open MCT version will be used.
-* Externally authored plugins will be installed.
-* A server will provide persistent storage, telemetry, and other shared data.
-* Authorization, authentication, and auditing will be handled by a server.
-
-
-## Security Procedures
-
-The Open MCT team secures our code base using a combination of code review,
-dependency review, and periodic security reviews. Static analysis performed 
-during automated verification additionally safeguards against common 
-coding errors which may result in vulnerabilities.
-
-
-### Code Review
-
-All contributions are reviewed by internal team members. External
-contributors receive increased scrutiny for security and quality,
-and must sign a licensing agreement.
-
-### Dependency Review
-
-Before integrating third-party dependencies, they are reviewed for security
-and quality, with consideration given to authors and users of these
-dependencies, as well as review of open source code.
-
-### Periodic Security Reviews
-
-Open MCT's code, design, and architecture are periodically reviewed
-(approximately annually) for common security issues, such as the
-[OWASP Top Ten](https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project).
-
-
-## Security Concerns
-
-Certain security concerns deserve special attention when deploying Open MCT,
-or when authoring plugins.
-
-### Identity Spoofing
-
-Open MCT issues calls to web services with the privileges of a logged in user.
-Compromised sources (either for Open MCT itself or a plugin) could
-therefore allow malicious code to execute with those privileges.
-
-To avoid this:
-
-* Serve Open MCT and other scripts over SSL (https rather than http)
-  to prevent man-in-the-middle attacks.
-* Exercise precautions such as security reviews for any plugins or
-  applications built for or with Open MCT to reject malicious changes.
-
-### Information Disclosure
-
-If Open MCT is used to handle or display sensitive data, any components
-(such as adapter plugins) must take care to avoid leaking or disclosing
-this information. For example, avoid sending sensitive data to third-party
-servers or insecure APIs.
-
-### Data Tampering
-
-The web application architecture leaves open the possibility that direct
-calls will be made to back-end services, circumventing Open MCT entirely.
-As such, Open MCT assumes that server components will perform any necessary
-data validation during calls issues to the server.
-
-Additionally, plugins which serialize and write data to the server must
-escape that data to avoid database injection attacks, and similar.
-
-### Repudiation
-
-Open MCT assumes that servers log any relevant interactions and associates
-these with a user identity; the specific user actions taken within the
-application are assumed not to be of concern for auditing.
-
-In the absence of server-side logging, users may disclaim (maliciously,
-mistakenly, or otherwise) actions taken within the system without any
-way to prove otherwise.
-
-If keeping client-level interactions is important, this will need to be
-implemented via a plugin.
-
-### Denial-of-service
-
-Open MCT assumes that server-side components will be insulated against
-denial-of-service attacks. Services should only permit resource-intensive
-tasks to be initiated by known or trusted users.
-
-### Elevation of Privilege
-
-Corollary to the assumption that servers guide against identity spoofing,
-Open MCT assumes that services do not allow a user to act with
-inappropriately escalated privileges. Open MCT cannot protect against
-such escalation; in the clearest case, a malicious actor could interact
-with web services directly to exploit such a vulnerability.
-

-security threats to Open MCT deployments in preparation of this document:

+
+## Chart 
+
+The `mct-chart` directive is used to support drawing of simple charts. It is 
+present to support the Plot view, and its functionality is limited to the 
+functionality that is relevant for that view.
+
+This directive is used at the element level and takes one attribute, `draw` 
+which is an Angular expression which will should evaluate to a drawing object. 
+This drawing object should contain the following properties:
+
+* `dimensions`: The size, in logical coordinates, of the chart area. A 
+two-element array or numbers. 
+* `origin`: The position, in logical coordinates, of the lower-left corner of 
+the chart area. A two-element array or numbers. 
+* `lines`: An array of lines (e.g. as a plot line) to draw, where each line is 
+expressed as an object containing: 
+    * `buffer`: A Float32Array containing points in the line, in logical 
+    coordinates, in sequential x,y pairs. 
+    * `color`: The color of the line, as a four-element RGBA array, where 
+    each element is a number in the range of 0.0-1.0. 
+    * `points`: The number of points in the line. 
+* `boxes`: An array of rectangles to draw in the chart area. Each is an object 
+containing: 
+    * `start`: The first corner of the rectangle, as a two-element array of 
+    numbers, in logical coordinates. 
+    * `end`: The opposite corner of the rectangle, as a two-element array of 
+    numbers, in logical coordinates. color : The color of the line, as a 
+    four-element RGBA array, where each element is a number in the range of 
+    0.0-1.0. 
+
+While `mct-chart` is intended to support plots specifically, it does perform 
+some useful management of canvas objects (e.g. choosing between WebGL and Canvas 
+2D APIs for drawing based on browser support) so its usage is recommended when 
+its supported drawing primitives are sufficient for other charting tasks.
