Discovery

Demos & Full documentation

Discovery is a dashboard as code tool. It includes dashboards generation (either through WarpScript or in an HTML page), single chart tiles and inputs as web components.

The global idea is to generate a structure which defines a dashboard and its tiles.

Tiles could depend on an execution result, so, your dashboard can change according to an alert for example.

A tile is an atomic dataviz component representing a line chart, a pie, a value, and so on. You can also define special tiles acting as inputs (ie: autocomplete, date-range, buttons, ...).

Usage

Events

Tiles emit events, they also trap events. A Dashboard also traps particular events.

Events are defined in the exec result of a tile, events are emitted when parsing done.

Tiles register handlers on particular tags and event's type. You can use regular expression.

Sample:

Events

{
    'title' 'My Dashboard With events'
    'tiles' [
      {
        'type' 'display'
        'title' 'Tile A'
        'w' 1 'h' 1 'x' 0 'y' 0
        'data' ''
        'options' { 'eventHandler' 'type=(data|style),tag=tes.*' } // Events handler
      }
      {
         'type' 'button'
         'title' 'Tile B'
         'options' { 'button' { 'label' 'Click me' } }
         'w' 1 'h' 1 'x' 1 'y' 0
         'macro' <% { 'data' <%
            RAND 100 * ROUND 'v' STORE // compute a random value
            { 
              'data' ''
              'events' [
                { 'tags' [ 'test' ] 'type' 'data' 'value' $v } } // Event emitter
               ]
             }
          %> } %>
       }
    ]
}

Event's types

data
Name Type Description
type data
tags string[] Targets
value GTS, GTS[], string, number, custom data The event emitter send data to the receiver, could be any kind of data including single value, GTS list or complex data. The receiver treat this event as an execution result.

Sample:

{ 'tags' [ 'random' ] 'type' 'data' 'value' 42 } }
style
Name Type Description
type style
tags string[] Targets
value {key:sting, value:string} Send CSS style to be applied by the receiver with a CSS selector as key

Sample:

{ 
  'tags' [ 'foo' ] 
  'type' 'style' 
  'value' {
    '.discovery-tile' 'background-color: red !important;'
    '.value' 'color: #ffffff;' 
  }
}
zoom

Only relevant for line, area, step, annotation and bar charts.

Name Type Description
type zoom
tags string[] Targets

Sample:

{ 'tags' [ 'chart2' ] 'type' 'zoom' }
xpath

Only relevant for SVG targets.

Name Type Description
type xpath
tags string[] Targets
value {key:sting, value:string}, string Attributes map or XML string for node replacement
selector string XPath selector starting at SVG (ie: /svg/g/g[2]/ellipse[3] )

If value is a string, the node targeted by the XPath selector is replaced by the XML provided in value.

If value is a map, the attributes of the node targeted by the XPath selector will be overridden with the values provided in the map. The key of the map must correspond to an attribute's name.

Sample:

{  // Node replacement
  'tags' [ 'svg' ] 
  'type' 'xpath'
  'value' '<' 'ellipse rx="15" ry="18" style="stroke:none;fill: red;" cx="50" cy="200"' + '/>' + 
  'selector' '/svg/g/g[2]/ellipse[1]'
}
{ // Attributes replacement
  'tags' [ 'svg' ]
  'type' 'xpath'
  'value' { 'rx' $v 'ry' $v }
  'selector' '/svg/g/g[2]/ellipse[3]'
}
popup

The only target is the Dashboard itself, you must declare handlers at the dashboard level.

Dashboard Event handler declaration:

{
    'title' 'My Dashboard With events'
    'options' { 'eventHandler' 'type=popup,tag=foo' }
    'tiles' [ ... ]
}

When event is trapped, a popup opens with a content.

Name Type Description
type popup
tags string[] Targets
value Tile, Dashboard Open a Tile or a complete dashboard in a popup.

Sample:

{ 
  'tags' [ 'foo' ] 
  'type' 'popup'
  'value' { // a Tile
     'type' 'area'
     'data' [
       NEWGTS 'data' RENAME 0.0 'v' STORE
       1 500 <% 1 s * NOW SWAP - NaN NaN NaN $v RAND 0.5 - + DUP 'v' STORE ADDVALUE %> FOR
     ]
  }
}
variable

You can inject variables into macro defined in Tiles and modify value with an event. But variables must be declared at the Dashboard level with an initial value.

Name Type Description
type variable
tags string[] Targets
value any New value for this variable or a key/value map value for variables
selector string Variable's name

Complete Sample for inputs:

{
  'title' 'My Dashboard With events'
  'vars' {
    'myVar' 42
  }
  'tiles' [
    {
      'type' 'input:text'
      'title' 'Input emitter'
      'options' {
        'button' { 'label' 'Send' }
      }
      'w' 2 'h' 1 'x' 0 'y' 0
      'macro' <% { 'data' $myVar 'events' [ { 'tags' [ 'random' ] 'type' 'variable' 'selector' 'myVar' } ] } %>
    }
    {
      'type' 'display'
      'title' 'Event var receiver'
      'w' 2 'h' 1 'x' 0 'y' 1
      'macro' <% $myVar %>
      'options' { 'eventHandler' 'type=(variable),tag=random' }
    } 
  ]
}

For Auto-refreshes:

{
 'title' 'My Dashboard With events'
 'vars' {
    'now' NOW
 }
 'tiles' [
   {
     'type' 'display'
     'title' 'Event data receiver'
     'w' 2 'h' 1 'x' 2 'y' 0
     'macro' <% $now %>
     'options' { 'eventHandler' 'type=variable,tag=random' }
   }
   {
     'type' 'display'
     'title' 'Event emitter'
     'w' 2 'h' 1 'x' 0 'y' 0
     'options' {  'autoRefresh' 1 }
     'macro' <% {
        'data' NOW
        'events' [
          { 'tags' [ 'random' ] 'type' 'variable' 'value' { 'now' NOW } }
         ]
       }
      %>
   }
 ]
}
