1. Where are Google Visualization API or issues with particular
visualizations to be reported?
2. We have encountered an issue where the Annotated Timeline will hang
and display -inf, nan for scale values.
The following reproduces the issue using the AJAX API Playground. It
is a minor alteration of the example code for the annotated timeline
(some null values, scaleType=allmaximize). After loading the
following, drag the right time slider such that the time range
selected is all null values for the second series.
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sold Pencils');
data.addColumn('string', 'title1');
data.addColumn('string', 'text1');
data.addColumn('number', 'Sold Pens');
data.addColumn('string', 'title2');
data.addColumn('string', 'text2');
data.addRows(6);
data.setValue(0, 0, new Date(2008, 1 ,1));
data.setValue(0, 1, 30000);
data.setValue(0, 4, null);
data.setValue(1, 0, new Date(2008, 1 ,2));
data.setValue(1, 1, 14045);
data.setValue(1, 4, null);
data.setValue(2, 0, new Date(2008, 1 ,3));
data.setValue(2, 1, 55022);
data.setValue(2, 4, 23432);
data.setValue(3, 0, new Date(2008, 1 ,4));
data.setValue(3, 1, 75284);
data.setValue(3, 4, 14334);
data.setValue(3, 5, 'Out of Stock');
data.setValue(3, 6, 'Ran out of stock on pens at 4pm');
data.setValue(4, 0, new Date(2008, 1 ,5));
data.setValue(4, 1, 41476);
data.setValue(4, 2, 'Bought Pens');
data.setValue(4, 3, 'Bought 200k pens');
data.setValue(4, 4, 66467);
data.setValue(5, 0, new Date(2008, 1 ,6));
data.setValue(5, 1, 33322);
data.setValue(5, 4, 39463);
var chart = new google.visualization.AnnotatedTimeLine
(document.getElementById('visualization'));
chart.draw(data, {displayAnnotations: true, scaleType:
'allmaximize', scaleColumns: [0,1]});
}
