CFD

Draw SVG Cumulative Flow Diagrams and predict the anticipated completion of work.

Install in your Node project with

and use it inside your code via

or, alternatively

Create the new cfd objects via

Parameters

• settings Object The configuration object for the diagram. All data for the diagram is provided with this object. In this configuration object, whenever a date is to be given, it can be an ISO 8601 String or a JavaScript Date object. A Moment object is also fine.
  • settings.title String? The title for the diagram.
  • settings.svg Object The DOM tree element, wich must be an svg tag. The diagram will be attached to this DOM tree element. Example:settings.svg = document.getElementById('cfdDiagram');'cfdDiagram' is the id of a svg tag.
  • settings.id String? The id of a domtree svg element, to which the diagram will be bound to. The id will only be used in case settings.svg is not provided.
  • settings.width Number? The width of the diagram in pixels, the margin settings have to be included in that width.
  • settings.height Number? The height of the diagram in pixels, the margin settings have to be included in that height.
  • settings.margin {top: Number, right: Number, bottom: Number, right: Number}? The margin for the diagram. Default values are:settings.margin = { top: 75, right: 210, bottom: 30, left: 40 }
  • settings.fromDate (String | Date)? The start date for the diagram. Example:settings.fromDate = '2018-09-01';
  • settings.toDate (String | Date)? The end date for the diagram. Example:settings.toDate = '2018-09-05';
  • settings.predict (String | Date)? To draw an indication line for the completion of work. The predict argument determines at what date to start drawing the line. Example:settings.predict = '2018-09-01';If no date is provided but the drawOptions allow to draw a prediction line, an automatic start date for that line will be calculated based on the first date something went to done.
  • settings.predictTarget (String | Date)? Provide a predict target that differs from the end date of the diagram (is before the end date)
  • settings.shortTermPredict Number? Indicate the number of days to go back from current date to determine a short term predict start date. This will be used to draw a second prediction line. If 0, no short term prediction line is drawn. Default is 0. Example:settings.shortTermPredict = 30;
  • settings.markers Array<{date: (String | Date), label: String}>? Highlight specific dates inside of the diagram with markers. Each marker is an object with a date for the marker and an optional label. It can as well have an optional color. Example:settings.markers = [ { date: '2018-09-03', label: 'M1', color: 'green' }, { date: '2018-09-10', label: 'M2' }];
  • settings.drawOptions Array<String>? An array to determine the parts to be drawn. Possible options:'title' - draw the title 'axis' - draw the x and y axis 'legend' - draw the legend information 'markers' - draw the markers 'predict' - draw the predict line 'focus' - draw detailed data when hovering the diagram By default all of these draw options are on.
  • settings.style Object? Influence the appearance of the diagram with typeface and colors. The defaults are:settings.style = { fontSize: 12, fontFamily: 'sans-serif', color: '#222', backgroundColor: '#fff', axis: {color: '#222'}, toDo: {color: '#ccc', stroke: '#fff'}, progress: {color: '#888', stroke: '#fff', pattern: false}, done: {color: '#222', stroke: '#fff'}, markers: {color: '#222', backgroundColor: '#fff'}, predict: {color: '#222', backgroundColor: '#fff', goodColor: '#222', troubleColor: '#222'}, shortTermPredict: {color: '#222', backgroundColor: '#fff', goodColor: '#222', troubleColor: '#222'} } A setting of settings.style.progress.pattern = true will ignore the color setting for progress and instead will create a pattern made of the toDo color and the done color. For the prediction, a goodColor is used whenever the workload can be completed within the scheduled amount of time and the troubleColor is used in case there is not sufficient time to complete all work.
  • settings.data {toDo: Array<String>, progress: Array<String>, done: Array<String>, unit: String, entries: Array<Object>} The data for the diagram. Example:settings.data = { toDo: ['new'], progress: ['test', 'dev'], done: ['done'], unit: 'points', entries: [ { date: '2018-09-03', new: 0, dev: 0, test: 0, done: 0 }, { date: '2018-09-04', new: 1, dev: 0, test: 0, done: 0 }, { date: '2018-09-05', new: 1, dev: 1, test: 0, done: 0 }, { date: '2018-09-06', new: 1, dev: 0, test: 1, done: 1 }, { date: '2018-09-07', new: 2, dev: 1, test: 0, done: 2 }, { date: '2018-09-08', new: 1, dev: 1, test: 2, done: 2 }, { date: '2018-09-09', new: 0, dev: 0, test: 1, done: 5 }, { date: '2018-09-10', new: 1, dev: 1, test: 0, done: 5 } ]}Each entry object must contain a date and the status counts for the toDo, progress and done status categories. The unit is the unit of measurement for the status counts and can hold any value. A value of 'points' indicates story points. An omitted unit will lead to interpreting the status counts as item counts. The status categories toDo, progress and done must contain the status values as strings that belong exactly to those categories. The rendering of the layers in the Cumulate Flow Diagram will follow the order of the status values provided inside of the status categories. All values of the done status category are always rendered at the bottom of the diagram, beginning from left to right. Then all progress status values, again left to right. Finally all new status values, of course left to right. For the above example: The done status layer is at the bottom, followed by the test and dev layer and finally the new layer is getting rendered.
  • settings.legend Object? Influence the appearance of the legend The defaults are:settings.legend = { toDo: 'To Do', progress: 'In Progress', done: 'Done' }
