I use Google Charts Line chart and have implement interpolateNulls = true.
This works great but now I want the line that interpolateNulls draws to be
dotted.
Is it possible to set lineDashStyle: [4,4] just on the interpolateNulls?
Here is some of my code:
var drawChart = function (data, type, firstIsAverage, vAxisHeader) {
var shift = (firstIsAverage === true) ? 0 : 1;
var fontname = 'Roboto';
var fontsize = 14;
var chartObject = {
type: type,
display: false,
data: data,
options: {
chartArea: {
left: 100,
top: 30,
width: 800,
height: 240
},
vAxis: {
title: vAxisHeader,
titleTextStyle: {
italic: false
}
},
// lineDashStyle: [4, 4], //Just want this on the
interpolateNulls
interpolateNulls: true, //Here is the interpolate
fontName: fontname,
fontSize: fontsize,
legend: 'none',
colors: colors.slice(shift),
isStacked: "true",
fill: 20,
displayExactValues: false
},
formatters: {}
};
setAllColumnsVisible(chartObject);
return chartObject;};
