create highcharts multiseries areaspline chart using codeigniter mysql 2

This is my modal
This is 1st series query
function student_reports(){
$this->db->select('monthname(a.view_date) as name, count(a.report_id) as
data');
$this->db->from('report_view_track a');
$this->db->where('a.user_id', 1);
$this->db->where('a.preview_mode', "report");
$this->db->group_by('monthname(view_date)');
$this->db->order_by('a.id', 'ASC');
$query = $this->db->get();
}
This is the result:
----------------------
|date | count |
----------------------
|2018-01-12 | 80 |
|2018-02-12 | 100 |
|2018-03-12 | 20 |
|2018-04-12 | 60 |
|2018-05-12 | 50 |
|2018-06-12 | 50 |
|2018-07-12 | 50 |
Second Query result is same format different count
second series query
function parents_reports(){
$this->db->select('monthname(a.view_date) as name, count(a.report_id) as
data');
$this->db->from('report_view_track a');
$this->db->where('a.user_id', 2);
$this->db->where('a.preview_mode', "report");
$this->db->group_by('monthname(view_date)');
$this->db->order_by('a.id', 'ASC');
}
this is controller
public function get_mainarray() {
$this->load->model('admin_model');
$main_array = $this->admin_model->student_reports();
echo json_encode($main_array,JSON_NUMERIC_CHECK);
}
public function get_mainarray1() {
$this->load->model('admin_model');
$main_array= $this->admin_model->parents_reports();
echo json_encode($main_array,JSON_NUMERIC_CHECK);

How to connect null values with dotted lines in highcharts

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
}]

How utilize flot.js to generate a monthly attendance chart?

How to make use of flot.js to create a attendance chart with it? something similar to the image linked.attendance chart

How can I add both plotLines and plotBands to a HighStocks graph using HighChart?

You have the wrong property name and you are not enclosing the plotLines in brackets. It should be like:
xAxis: {
type: 'datetime',
floor: Date.UTC(2017, 2, 2),
ceiling: Date.UTC(2017, 2, 9),
plotLines: [{
value: Date.UTC(2017, 2, 8),

[gd(2014, 5, 1), 1], [gd(2014, 6, 1), 3], [gd(2014, 7, 1), 1], [gd(2014, 8, 1), 5],
[gd(2014, 9, 1), 2], [gd(2014, 10, 1), 3], [gd(2014, 11, 1), 2], [gd(2014, 12, 1), 1]];
This is the dataset, but look that I put both dataset in 2014 year because if I put 2014 in one dataset and 2013 in another, I miss the overlap effect and I need that effect for comparsion.
This is what happens if a put the 2013 year in one dataset and 2014 in another (image below)
How can I do the same chart, but with this overlap effect, using the 2013 year in one dataset?
This also will fix my hover functionallity.
Code
var data1 = [
[gd(2014, 1, 1), 4], [gd(2014, 2, 1), 8], [gd(2014, 3, 1), 4], [gd(2014, 4, 1), 10],
[gd(2014, 5, 1), 4], [gd(2014, 6, 1), 16], [gd(2014, 7, 1), 5]];
var data2 = [
[gd(2014, 1, 1), 1], [gd(2014, 2, 1), 0], [gd(2014, 3, 1), 2], [gd(2014, 4, 1), 0],

[gd(2014, 9, 1), 2], [gd(2014, 10, 1), 3], [gd(2014, 11, 1), 2], [gd(2014, 12, 1), 1]];

You use the concept of multiple axes, but just hide the second axis.
To do this you create two data sets, each with their own axis:
var data2014 = {
label: "2014",
data: data1,
xaxis: 1
};
var data2013 = {
label: "2013",
data: data2,
xaxis: 2
};
and then in the axes option setting, set ticks to false to hide one axis.
The max setting for the 2014 data is important, otherwise the data set will scale to fill the whole graph:
xaxes: [{
mode: "time",
tickSize: [1, "month"],
tickLength: null,
color: "#838383",
timeformat: "%b",
max: (new Date("2014/12/1")).getTime()
},{
ticks: false
}],
