How to display an histogram given a bag

Hi

b := Bag new.
b add: 1 withOccurrences: 5.
b add: 3 withOccurrences: 4.
b add: 6.
b

and I would like to display it as an histogram with roassal.

Re: How to display an histogram given a bag

You can try something like that:

     b := Bag new.
     b add: 1 withOccurrences: 5.
     b add: 3 withOccurrences: 4.
     b add: 6.
     b.

    v := RTDoubleGraphBuilder new.
    ds:=RTStackedDataSet new.
    ds interaction popup.
    ds points: b valuesAndCounts keys.
    ds y:[:c|cb valuesAndCounts at: c].
    ds barShape color: Color red; width: 15.
    v add: ds.
    v axisX.
    v axisYWithNumberOfTicks: 5.
    v open

I'm working with an old version of Roassal (version 761 of the Roassal package) then I don't know if it's working with a more recent version.

Otherwise there is examples in the Grapher Menu of the Roassal examples.

Re: How to display an histogram given a bag

If you want to use the last version:

b := Bag new.

b add: 1 withOccurrences: 5.

b add: 3 withOccurrences: 4.

b add: 6.

v := RTGrapher new.

ds:=RTData new.

ds interaction popup.

ds points: b valuesAndCounts keys.

ds y:[:c|b valuesAndCounts at: c].

ds barShape color: Color red; width: 15.

v add: ds.

v axisX.

v axisYWithNumberOfTicks: 3.

v build.

v open

But, the abscissa labels are not accurate:

Not sure that you are interested with that but with the implementation of ChartJs i have done for seaside:

stefExample: html

| b chartData |

b := Bag new.

b add: 1 withOccurrences: 5.

b add: 3 withOccurrences: 4.

b add: 6.

chartData := Chart2dData xObjects: (1 to: 6) function: [ :aValue | b valuesAndCounts at: aValue ifAbsent: 0 ].

chartData chartType: ChartBar.

html render: (ChartJsComponent data: chartData)

Re: How to display an histogram given a bag

So we really cannot do that with Roassal inside the image ?

BTW, what we have to load to use your ChartJs ?

In reply to this post by stepharo

In a playground, I try:

b := Bag new.
b add: 1 withOccurrences: 5.
b add: 3 withOccurrences: 4.
b add: 6.
b asArray histogram

But the result is buggy apparently ...

where is that ChartJs thing?

Stef, there is a histogram message one can send to a collection.

Otherwise there is examples in the Grapher Menu of the Roassal examples.

So we really cannot do that with Roassal inside the image ?

BTW, what we have to load to use your ChartJs ?

execute this:

Metacello new

smalltalkhubUser: 'PharoExtras' project: 'ChartJs';

configuration: 'ChartJs';

onWarningLog;

version: #development;

load

then run seaside server and go to the demo:

http://localhost:8080/ChartJsDemo

Not sure that you are interested with that but with the implementation of ChartJs i have done for seaside:

stefExample: html

          | b chartData |

          b := Bag new.

          b add: 1 withOccurrences: 5.

          b add: 3 withOccurrences: 4.

          b add: 6.

          chartData := Chart2dData xObjects: (1 to: 6) function: [ :aValue | b valuesAndCounts at: aValue ifAbsent: 0 ].

          chartData chartType: ChartBar.

          html render: (ChartJsComponent data: chartData)

Thanks vincent but how can I get a real histogram?
with empty columns for empty values?

But, the abscissa labels are not accurate:

You can try something like that:

     b := Bag new.
     b add: 1 withOccurrences: 5.
     b add: 3 withOccurrences: 4.
     b add: 6.
     b.

    v := RTDoubleGraphBuilder new.
    ds:=RTStackedDataSet new.
    ds interaction popup.
    ds points: b valuesAndCounts keys.
    ds y:[:c|cb valuesAndCounts at: c].
    ds barShape color: Color red; width: 15.
    v add: ds.
    v axisX.
    v axisYWithNumberOfTicks: 5.
    v open

I'm working with an old version of Roassal (version 761 of the Roassal package) then I don't know if it's working with a more recent version.

Otherwise there is examples in the Grapher Menu of the Roassal examples.

Hi

I have a bag

     b := Bag new.
     b add: 1 withOccurrences: 5.
     b add: 3 withOccurrences: 4.
     b add: 6.
     b

and I would like to display it as an histogram with roassal.

The Roassal #histogram should just work in a cool way.

Make easy things easy, you will get great response.

Re: How to display an histogram given a bag

There are numerous ways to draw an histogram.

Here some examples:

b := Bag new.
b add: 1 withOccurrences: 5.
b add: 3 withOccurrences: 4.
b add: 6.
b add: 10.
v := RTGrapher new.
ds := RTData new.
ds interaction popup.
ds points: b valuesAndCounts keys.
ds y: [:c|b valuesAndCounts at: c] .
ds barChartWithBarTitle: #yourself rotation: 0.
v add: ds.
v axisX noTick.
v

b := Bag new.
b add: 1 withOccurrences: 5.
b add: 3 withOccurrences: 4.
b add: 6.
b add: 10.
v := RTGrapher new.
ds := RTData new.
ds interaction popup.
ds points: b valuesAndCounts keys.
ds y: [ :c|b valuesAndCounts at: c] .
ds x: #yourself.
ds barShape.
v add: ds.
v axisX numberOfLabels: 10; noDecimal.
v axisY noDecimal.
v

Indeed, #histogram is buggy.
