I have a stackblitz here - https://stackblitz.com/edit/ng-first-v-last-arrows-t1tt8e?embed=1&file=src/app/bar-chart.ts&hideNavigation=1



I have two separate bars that are created with different start and finish value.



Currently the y.domain is created with hard coded numbers



this.y.domain([93, 106])


The data looks like this.



 {

   phase: 'One',

   start: 102,

   finish: 100

 },

 {

   phase: 'One',

   start: 98,

   finish: 101

 }


I need the lowest value from the start values and the highest from the finish values.



How can I get these value in the y.domain array






d3.js

  • you need the highest and lowest value of the start and finish combined, put all of them in an array and call d3.extent

Quarantine

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy
