Bug: NumberRangeFilter and filtering values between 0 and 1.

[orwant]

What steps will reproduce the problem? Please provide a link to a
demonstration page if at all possible, or attach code.

I have a table with values between 0 and 1 (i.e. 0.33 etc) which I want to filter using
a NumberRangeFilter. Everything works fine except that the NumberRangeFilter only can
be 0 or 1... nothing in between. It seems that unitIncrement cant be smaller than 1.


Below is code you can use on Google Chart Playground to simulate the bug: 

function drawVisualization() {
  // Prepare the data
  var data = google.visualization.arrayToDataTable([
    ['Name', 'Age'],
    ['Michael' , 0.12],
    ['Elisa', 0.20],
    ['Robert', 0.7],
    ['John', 0.54],
    ['Jessica', 0.22],
    ['Aaron', 0.3],
    ['Margareth', 0.42],
    ['Miranda', 0.33]
  ]);

  // Define a NumberRangeFilter slider control for the 'Age' column.
  var slider = new google.visualization.ControlWrapper({
    'controlType': 'NumberRangeFilter',
    'containerId': 'control1',
    'options': {
      'filterColumnLabel': 'Age',
      'minValue': 0,
      'maxValue': 1,
      'ui': {'unitIncrement' : 0.01}
    }
  });

  // Define a bar chart
  var barChart = new google.visualization.ChartWrapper({
    'chartType': 'BarChart',
    'containerId': 'chart1',
    'options': {
      'width': 400,
      'height': 300,
      'hAxis': {'minValue': 0, 'maxValue': 1},
      'chartArea': {top: 0, right: 0, bottom: 0}
    }
  });

  // Create the dashboard.
  var dashboard = new
google.visualization.Dashboard(document.getElementById('dashboard')).
    // Configure the slider to affect the bar chart
    bind(slider, barChart).
    // Draw the dashboard
    draw(data);

} 


What component is this issue related to (PieChart, LineChart, DataTable,
Query, etc)?

NumberRangeFilter as far as I have tested. Might be more components that are affected.



Are you using the test environment (version 1.1)?
(If you are not sure, answer NO)

NO


What operating system and browser are you using?

Windows 7 and FF 11.0.

I have noticed that when I use the ui.ticks option, I can set it to be anything less
than or equal to the high value of the numberRangeFilter slider (when that value is
an integer greater than 1), but when I set it to be greater than the high value, the
slider still only increments by 1. For example, in a slider from 0 to 10, when I set
the ui.ticks to 3 it will increment by 3.33333334, when I set it to 10 it will increment
by 1, when I set it to 20 it still increments by 1. This implies that decimal value
ticks are allowed, but I can't get it to work for ranges from 0 to 1. I am using it
with a column chart. For data that falls between 0 and 1 I have to multiply the values
by 100 or 1000 to make the NumberRangeFilter useful (not an optimal solution).

The documentation ought to say that the unitIncrement and blockIncrement cannot be smaller
than 1.  But we have a pending change that will address this deficiency.  Thanks for
the suggestion.

When the value granularity is provided, the range values at each end of the control
should also display at that level of granularity by default. If my unitIncrement is
0.1, then in most cases I would want to see #.# at both ends of the scale.  Thanks
for a great product!

As you seem to have noticed, the unitIncrement can now be less than 1.  It ought to
be the case that the default format will show the appropriate number of decimal digits
based on the unitIncrement, but perhaps there is a bug.  Thanks for your comment.

I can't get the unitIncrement to work for me using this.  Is it my code or is it still
not available?:

        // Define a NumberRangeFilter slider control for the 'Age' column.
        var slider = new google.visualization.ControlWrapper({
          'controlType': 'NumberRangeFilter',
          'containerId': 'toolbar',
          'options': {
            'filterColumnLabel': 'stat2',
            'minValue': 0,
            'maxValue': 3,
            'ui': {
            'label': 'stat2',
            'unitIncrement': 0.5}
          }

        });

Hi

Has anything moved on this? I can't get the unitIncrement to be less than 1 nor ui : {ticks} to be greater than the maximum control value.

thanks
