google stacked bar chart do not want to display 0 bar - charts

Question

In a google stacked bar chart is there any way to have it not display a bar with a zero value?
I do not want the thin red line on the first bar or the hover to show.
Here is my code:
var data = google.visualization.arrayToDataTable([
['Class', 'Cost', 'Savings', { role: 'annotation' } ],
['Current State Run', 140999460, 0, ''],
['Total Future State Run', 109351526, 31647934, '']
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1,
{ calc: "stringify",
sourceColumn: 1,
type: "string",
role: "annotation" },
2,
{ calc: formatter,
sourceColumn: 2,
type: "string",
role: "annotation" },
3]);
function formatter(dataTable, row) {
if (data.getValue(row, 2))
return parseInt(data.getValue(row, 2)).toLocaleString()
else
return '';
}

Answer 1

convert the zero value to null,
this will hide the line and tooltip.
if needed, you can use a DataView and calculated columns,
to dynamically change the zeroes to null
see following working snippet...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['Class', 'Cost', 'Savings'],
['Current State Run', 140999460, 0],
['Total Future State Run', 109351526, 31647934]
]);
var view = new google.visualization.DataView(data);
var viewCols = [0];
for (var i = 1; i < data.getNumberOfColumns(); i++) {
addCalcs(i);
}
view.setColumns(viewCols);
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
var options = {
isStacked: true
};
chart.draw(view, options);
function addCalcs(col) {
viewCols.push({
calc: function (dt, row) {
return getNullValue(dt, row, col);
},
label: data.getColumnLabel(col),
type: data.getColumnType(col)
});
viewCols.push({
calc: function (dt, row) {
return formatter(dt, row, col);
},
type: 'string',
role: 'annotation'
});
}
function formatter(dataTable, row, col) {
if (data.getValue(row, col)) {
return parseInt(data.getValue(row, col)).toLocaleString()
} else {
return '';
}
}
function getNullValue(dataTable, row, col) {
var value = dataTable.getValue(row, col);
if (value === 0) {
return null;
}
return value;
}
});
