as you can see my data is ordered by date in ascending format, but I get error #15??
any help is appreciated.

The undefined symbol error appears when you specify a value of 5 or above for _symbolIndex. I'm not sure what your _symbolIndex settings are meant to be doing, they're not part of the API docs, but if you take them out, the problem goes away.
The error 15 is being caused by a misordered date. The Date.UTC function (confusingly) expects a zero-based month parameter but you're giving it one-based months, so where you've got:
Date.UTC(2014, 01, 29, 10, 30, 12)
you haven't set January 29th as you might expect, you've set February 29th (in a non leap year) which JavaScript interprets as March 1st.

How to correctly use datetime data on the continuous axis of a Google Chart?

So as seen in the code snippet below, I'm just trying to create a chart/control combination dashboard via Google Charts and I'm having some difficulties with datetime fields, despite following the reference material on that.
My areas of confusion are as follows:
1. Why do the dates shown on the chart appear to be off by one month? I've entered dates for August & September, yet September & October are showing up on the chart.
2. Why does the chart displayed for the ChartRangeFilter appear to jump back to older dates (around the October 2 mark)?

In addition to what #Z. Bagley wrote, to resolve this problem you can use couple solutions. The first one would be concerning using Highstock chart. In Highstock chart there is a property called ordinal (true by default) which distributes points equally on xAxis. Secondly, you can use breaks along with setting a new xAxis extremes to decrease distance between the last two dates. You can also try to add a scrollbar.
API Reference:
http://api.highcharts.com/highstock/xAxis.ordinal
http://api.highcharts.com/highcharts/xAxis.breaks
http://api.highcharts.com/highstock/scrollbar
Examples:
http://jsfiddle.net/pbdor59x/ - using Highstock and ordinal property
http://jsfiddle.net/abwpqs19/ - using breaks

Give your layout Object a scene, and set your desired range on its axis, yaxis, and (if you like) zaxis properties. E.g.
var MIN_VAL = -100, MAX_VAL = 100;
var layout = {
scene:{
axis: {
nticks: 10,
range: [ MIN_VAL, MAX_VAL ]
},
yaxis: {
nticks: 10,
range: [ MIN_VAL, MAX_VAL ]
},
zaxis: {
nticks: 7,
range: [ MIN_VAL, MAX_VAL ]
},
aspectmode: "manual",
aspectratio: { x: 1, y: 1, z: 0.7 },
bgcolor : '#98ff6d'
},
autosize: false,
width: 400,
height: 300,
margin: { l: 0, r: 0, b: 50, t: 50, pad: 4 }
};
Plotly.newPlot('plot', data, layout);
Plotly has a working example (that shows the use of even more layout options) on CodePen.

How to connect null values with dotted lines in highcharts

I want to connect null values with dotted lines in the chart.
Below is the url to JS fiddle where my code resides -
data: [
[Date.UTC(2016, 1, 1),null],
[Date.UTC(2016, 2, 1),null],
[Date.UTC(2016, 3, 1),500],
[Date.UTC(2016, 4, 1),600],
[Date.UTC(2016, 5, 1),null],
[Date.UTC(2016, 6, 1),700],
[Date.UTC(2016, 7, 1),null],
[Date.UTC(2016, 8, 1),null],
[Date.UTC(2016, 9, 1),null],
[Date.UTC(2016, 10, 1),null],
[Date.UTC(2016, 11, 1),null],
[Date.UTC(2017, 0, 1),500]
],
http://jsfiddle.net/Ashish_developer/ue0wb8w0/
You can use series.zones to define which part of the graph will be dashed.
Based on your data, the algorithm for building the zones array could be sth like this (feel free to adjust it the way you want):
function buildZones(data) {
var zones = [],
i = -1, len = data.length, current, previous, dashStyle, value;
while (data[++i] === null);
zones.push({
value: i
});
while (++i < len) {
previous = data[i - 1];
current = data[i];
dashStyle = '';
if (previous !== null && current === null) {
dashStyle = 'solid';
value = i - 1;
} else if (previous === null && current !== null) {
dashStyle = 'dot';
value = i;
}
if (dashStyle) {
zones.push({
dashStyle: dashStyle,
value: value
});
}
}
return zones;
}
Series config:
series: [{
zones: buildZones(data),
zoneAxis: 'x',
data: data,
connectNulls: true
}]

The setting you want is tickInterval, not point interval. You also need to specify startOnTick: true to make it start on your first point.
xAxis: {
type: 'datetime',
tickInterval: 13 * 24 * 3600 * 1000, //half month interval
pointStart: Date.UTC(2014, 7, 26),
startOnTick: true,
dateTimeLabelFormats: {
month: '%b %e',
year: '%b'
}
},
