Issues with naming ranges for charts within the Google Spreadsheet Script - charts

Question

I've been trying for days to create charts with an intelligent range, that differs when the data in the google spreadsheet is updated. However i succeeded doing so, i can't get the .setOption aspect to work. I want for example, a title, description etc with the chart. But this is not the main issue since i can insert there by hand.
More important however is the range name, because there isn't when i use the script. So, within the chart it is not possible to see what each column represents, and i really want to fix that. I tried to use the .setNamedRange() aspects, but that is not working.
Someone who can help me with that?
function check() {
var sheet = SpreadsheetApp.getActiveSheet();
var end = sheet.getLastRow();
var start = (end - 5);
var endnew = (end - 4);
var startnew = (end - 6);
if(sheet.getCharts().length == 0){
Logger.log("Er is geen grafiek");
var chartBuilder = sheet.newChart()
.asColumnChart().setStacked()
.addRange(sheet.getRange("A" + startnew + ":" + "A" + endnew)) // should have a name
.addRange(sheet.getRange("B" + startnew + ":" + "B" + endnew)) // should have a name
.addRange(sheet.getRange("E" + startnew + ":" + "E" + endnew)) //should have a name
.setOption('title', 'Effectief gebruik kantoorruimte') //not working
.setPosition(10, 10, 0, 0)
var chart = chartBuilder.build();
sheet.insertChart(chart);
}
else{
Logger.log("Er is wel een grafiek");
var charts = sheet.getCharts();
for (var i in charts) {
var chart = charts[i];
var ranges = chart.getRanges();
var builder = chart.modify();
for (var j in ranges) {
var range = ranges[j];
builder.removeRange(range);
builder
.addRange(sheet.getRange("A" + (start) + ":" + "A" + end)) //should have a name
.addRange(sheet.getRange("B" + (start) + ":" + "B" + end)) //should have a name
.addRange(sheet.getRange("E" + (start) + ":" + "E" + end)) // should have a name
.setOption('title', 'Effectief gebruik kantoorruimte')
.build();
sheet.updateChart(builder.build());
}
}
}
}

I'm assuming that this code is the issue?
builder
.addRange(sheet.getRange("A" + (start) + ":" + "A" + end))
Maybe try using the JavaScript toString() method to make sure that your text formula is working.
.addRange(sheet.getRange("A" + start.toString() + ":" + "A" + end.toString()))
There is a different format that you can use:
getRange(row, column, numRows, numColumns)
So, it would be:
getRange(start, 1, 1, numColumns)
That starts on row "start" in column A. It gets one row of data, and how ever many number of columns.
