#13807 patchwelcome Implementing "value" feature from dojox.charting.DataSeries in dojox.charting.DataChart Eugene Lazutkin Jose Moreira
Description

According to my current understanding of Dojo 1.6.1 code (and also a read of 1.7.0b5), dojox.charting.DataChart? has a "fieldName" constructor argument, which is used to extract the series value (or values if the property value is a array) from a datastore item, for example:

http://bugs.dojotoolkit.org/browser/dojo/dojox/trunk/charting/DataChart.js#L371

var field = this.getProperty(m, this.fieldName);
this.seriesData[nm].push(field);

Given a dataset in which the developer only wants some specific properties of an item plotted from a flat format, for example only 'cpu',

'rsize', 'vsize' and 'vprvt' from :

{
  "identifier": "pid",
  "idAttribute": "pid",
  "label": "cmd",
  "labelAttribute": "cmd",
  "items": [
    {"pid": 1639, "cmd": "kernel_task"  , "cpu": 10.3   , "rsize": 659000000  , "vsize": 18000    , "vprvt": 81000    },
    {"pid": 1572, "cmd": "iTerm"        , "cpu": 10.0   , "rsize": 139400000  , "vsize": 9000     , "vprvt": 52000    },
    {"pid": 1524, "cmd": "top"          , "cpu": 7.7    , "rsize": 350000000  , "vsize": 46000    , "vprvt": 17000    },
    {"pid": 1470, "cmd": "launchd"      , "cpu": 15.4   , "rsize": 186800000  , "vsize": 50000    , "vprvt": 57000    },
    {"pid": 1823, "cmd": "Colloquy"     , "cpu": 5.2    , "rsize": 116000000  , "vsize": 6873000  , "vprvt": 226000   },
    {"pid": 1442, "cmd": "WindowServer" , "cpu": 4.5    , "rsize": 157000000  , "vsize": 2525000  , "vprvt": 328000   },
    {"pid": 1340, "cmd": "iTunes"       , "cpu": 3.8    , "rsize": 700000000  , "vsize": 3293000  , "vprvt": 81000    },
    {"pid": 1556, "cmd": "backupd"      , "cpu": 3.4    , "rsize": 150000000  , "vsize": 2555000  , "vprvt": 57000    },
    {"pid": 1363, "cmd": "Finder"       , "cpu": 2.7    , "rsize": 600000000  , "vsize": 2667000  , "vprvt": 81000    },
    {"pid": 1329, "cmd": "mdworker"     , "cpu": 2.3    , "rsize": 100000000  , "vsize": 2416000  , "vprvt": 36000    }
   ]
}

it's currently not possible to only plot a subset of the properties using dojox.charting.DataChart? directly or pre-processing the data (as far as i know).

A possible solution could be to mimic dojox.charting.DataSeries?, in which it's "value" property:

value: Function|Object|String|Null: Function, which takes a store, and an object handle, and produces an output possibly inspecting the store's item. Or a dictionary object, which tells what names to extract from an object and how to map them to an output. Or a string, which is a numeric field name to use for plotting. If undefined, null or empty string (the default), "value" field is extracted.

can be passed a function which receives the datastore item and returns a transformation, for example as described in the Dojo docs:

function trans1(store, item){
  // let's create our object
  var o = {
    x: store.getValue(item, "order"),
    y: store.getValue(item, "value"),
    tooltip: store.getValue(item, "title"),
    color: store.getValue(item, "urgency") ? "red" : "green"
  };
  // we can massage the object, if we want, and return it
  return o;
}

In this particular case, an implementation could be:

function trans_subset(store, item){
  // let's create our object
  var o = {
    "cpu": store.getValue(item, "cpu"),
    "rsize": store.getValue(item, "rsize"),
    "vsize": store.getValue(item, "vsize"),
    "vprvt": store.getValue(item, "vprvt"),
  };
  // we can massage the object, if we want, and return it
  return o;
}

Although it it more complex that for example allowing "fieldName" to be an array of property names (that could be another possible solution), this solution would also allow the developer to transform the property values, as also intented on the dojox.charting.DataSeries? "value", for example:

/**
  * function that normalizes Kb/Mb/Gb bytes to bytes
  */
function normalizeToBytes(/*String*/ value)  {
    //TODO do me
}

function trans_subset(store, item){
  var o = {
    "cpu": store.getValue(item, "cpu"),
    "rsize": normalizeToBytes(store.getValue(item, "rsize")),
    "vsize": normalizeToBytes(store.getValue(item, "vsize")),
    "vprvt": normalizeToBytes(store.getValue(item, "vprvt")),
  };
  return o;
}
#14526 fixed Tooltips do not position correctly on charts after scroll cjolif zebulonevans
Description

Steps to reproduce the problem.

  1. Put a bar chart or pie chart on a page with a tooltip.
  2. Mouse over the chart to show the tooltip.
  3. Mouse off the tooltip so it hides
  4. Scroll the page down.
  5. Mouse over the tooltip again

The tooltip will remain in the original position.

Expected Behavior:

The tooltip should appear lower on the page not in the original position.

This was introduced due to ticket #12392 around line 141 in Tooltip.js when this change occurred:

var lt = dojo.coords(this.chart.node, true);

to

var lt = this.chart.getCoords();
