highcharts - log axis not working

I have a high chart code like this:
Highcharts.chart('linechart', {
chart: {
backgroundColor:'rgba(255, 255, 255, 0.8)',
borderRadius:5,
},
title: {
text: 'ROC Graph'
},
subtitle: {
text: 'Learning Evaluation'
},
xAxis: {
min: 0,
max: 1,
tickWidth:1,
tickPositions: [0.001, 0.01, 0.1,1]
},
yAxis: {
max: 1,
tickInterval:0.1,
title: {
text: 'Number of Employees'
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle'
},
plotOptions: {
series: {
pointStart: 0.30
}
},
});
And my javascript code:
for(j=0; j<data.roc_buffer[i]['xs'].length/10;j++){
x_plot = data.roc_buffer[i]['xs'][10*j]
y_plot = data.roc_buffer[i]['ys'][10*j]
plot_buffer[j] = {'x':x_plot, 'y':y_plot}
}
roc_chart.addSeries({
name: data.roc_buffer[i]['plotname'],
data: plot_buffer
});
It work out fine like this
However, I want the [0.001,0.01,0.1,1] all have same width so I need to adjust the xaxis to type logarithm. So I switch my code to:
xAxis: {
type: 'logarithmic',
minorTickInterval: 0.1
},
Now the line disappear...
Also my data is something like
[{x:integer,y:integer},{x:integer,y:integer},{x:integer,y:integer},...]

What I understand.
Your xAxis and yAxis both value dynamically generated.
You can set data using setData method for yAxis and setCategories for xAxis.
$('#button').click(function () {
highchart.series[0].setData([1, 2, 4, 8, 16]);
highchart.xAxis[0].setCategories(['J', 'F', 'M', 'A', 'M']);});

Plot Bar chart and Line series chart on separate x-axis in Highcharts out of common dataset

I got common dataset for both line series and bar graph . In other words dataset consists both line series dataset and bar graph dataset. Now I want to plot line series graph on separate x-axis and bar graph on separate x-axis. And want to control them both from same frame. Like both tooltip for both should come in same popup, from same section I can show and hide them. Attached my screenshot , currently they are sharing same x-axis. I want to separate them. Here is my piece of code.
for(j=0; j<timelinejson.length; j++){
seriesOptions[j] = {
//name: selectedMarkers[i],
name: timelinejson[j].marker_desc,
data: mData,
marker : {
enabled : true,
radius : 3
},
type : 'spline',
tooltip : {
valueDecimals : 2
}
};
}
seriesOptions[10] = {
name: 'Speed',
data: [[1372636800000, 0.16], [1375315200000, 0.36], [1377993600000, 0.4], [1380585600000, 0.68], [1383264000000, 0.6], [1385856000000, 0.64], [1388534400000, 0.68], [1391212800000, 0.69], [1393632000000, 0.71], [1396310400000, 0.73], [1398902400000, 0.74], [1401580800000, 0.75], [1404172800000, 0.76], [1406851200000, 0.17], [1409529600000, 0.67], [1412121600000, 0.18], [1414800000000, 0.58], [1417392000000, 0.28], [1420070400000, 0.58], [1422748800000, 0.49], [1425168000000, 0.39], [1427846400000, 0.29], [1430438400000, 0.59], [1433116800000, 0.19]],
type: 'column',
valueDecimals: 1
};
drawTrend(seriesOptions,temp)
function drawTrend(marker_array_main,temp) {
$('#trendChart'+temp).highcharts('StockChart', {
chart: {
height: 400
//width: 500
},
rangeSelector: {
selected: 4
},
yAxis: {
/*labels: {
formatter: function () {
return (this.value > 0 ? ' + ' : '') + this.value + '%';
}
},*/
plotLines: [{
value: 0,
width: 2,
color: 'silver'
}]
},
legend: {
enabled: true,
align: 'right',
verticalAlign: 'top',
layout: 'vertical',
x: 0,
y: 100
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> <br/>',
valueDecimals: 2
},
series: marker_array_main
});
}

I think that you can use multiple yAxis in case of your chart. You can add as many yAxes as you want and you can connect your series with this axes using yAxis:x parameter in your Series object.
x value is an index of specific axis in yAxis array.
yAxis: [{
labels: {
align: 'right',
x: -3
},
title: {
text: 'OHLC'
},
height: '60%',
lineWidth: 2
}, {
labels: {
align: 'right',
x: -3
},
title: {
text: 'Volume'
},
top: '65%',
height: '35%',
offset: 0,
lineWidth: 2
}],
series: [{
type: 'column',
name: 'Volume',
data: volume,
yAxis: 1,
dataGrouping: {
units: groupingUnits
}
}]
Here you can find simple example of this kind of chart from Highcharts demos:

MACD + High chart Graph plotting issue

I'm stuck at MACD plotting in highchart.
I don't understand where I'm doing wrong. Please follow jsfiddle link and try to solve and plotting graph for MACD only.
$(function () {
$('#container').highcharts({

}
]
});
});

Accoring to the code: https://rawgit.com/laff/technical-indicators/master/technical-indicators.src.js it looks like periods are hardcoded, so it is a reason why your macd is not calculated. You you no enough points.

HighStock HighCharts Setting Flag on Click Event

I'm using the HighStock version of HighCharts to create a series of data in charts. I've got a candlestick graph, on top of a bar graph, on top of a histogram. The candlestick points are clickable. I want to add a flag to the point on the candlestick chart that they just clicked on.
Here is some of the code I've tried playing with:
// create the chart
chart = new Highcharts.StockChart({
chart: {
renderTo: 'container',
alignTicks: false
},
rangeSelector: {
selected: 1
},
title: {
text: 'DJIA Historical'
},
yAxis: [{
title: {
text: 'OHLC'
},
height: 300,
lineWidth: 2
}, {
title: {
text: 'Volume'
},
top: 400,
height: 100,
offset: 0,
lineWidth: 2
}, {
title: {
text: 'MACD'
},
top: 520,
height: 100,
offset: 0,
lineWidth: 1
}],
series: [{
type: 'candlestick',
name: 'DJIA',
data: ohlc,
events: {
click: function(event) {
console.log(chart);
chart.series[6].setData(event.point);
}
},
dataGrouping: {
units: groupingUnits
}
}, {
type: 'column',
name: 'Volume',
data: volume,
yAxis: 1,
dataGrouping: {
units: groupingUnits
}
}, {
type: 'column',
name: 'Histogram',
pointPadding: 0,
groupPadding: 0,
data: histogram,
yAxis: 2,
color: '#666666'
}, {
type: 'line',
name: 'MACD',
pointPadding: 0,
groupPadding: 0,
data: macd,
yAxis: 2,
color: '#0000FF'
}, {
type: 'line',
name: 'Signal',
pointPadding: 0,
groupPadding: 0,
data: signal,
yAxis: 2,
color: '#000000'
}, {
type: 'flags',
name: 'Active Point',
data: [],
onSeries: ohlc,
shape: 'squarepin'
}]
});
})
The chart doesn't throw any JavaScript errors, but it's not creating the flag. At the very least, it's not showing it. I want to essentially have it draw the flag over the candlestick they clicked. If they click another spot, I want to remove the old flag and draw a new one on the new point. I figured this was best done by adding and removing data from the series but haven't had much luck.
Any help on this would be greatly appreciated!

Firstly, A js-fiddle example would be highly appreciate to understand your problem.
From the best that I understood about your problem, try this (Assuming 5 is the index of your flag series, your code seems to be using index 6?!)
click: function(event) {
this.chart.series[5].addPoint({
x: event.point.x,
title: 'hey you clicked me'
});
}
my fiddled code # http://jsfiddle.net/U2Z2x/1/
Since you seem to be interested in showing only 1 flag, as you were rightly using setData, that seems to be your best bet, just a catch, setData expects an array, and you passing a single value, also the format of the point needs to be slightly redone for flag type series
click: function(event) {
this.chart.series[5].setData([{
x: event.point.x,
title: 'hey you clicked me'
}]);

how to hide highchart x - axis data values

I am drawing a bar chart using highchart.js
I do not want to show the x - axis data values.
Can any one tell me which option does it?
full config:
var chart = new Highcharts.Chart({
chart: {
renderTo: container,
defaultSeriesType: 'bar'
},
title: {
text: null
},
subtitle: {
text: null
},
xAxis: {
categories: [''],
title: {
text: null
},
labels: {enabled:true,y : 20, rotation: -45, align: 'right' }
},
yAxis: {
min: 0,
gridLineWidth: 0,
title: {
text: '',
align: 'high'
}
},
tooltip: {
formatter: function () {
return '';
}
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
},
pointWidth: 35,
color: '#D9CDC1'
}
},
legend: {
enabled: false
},
credits: {
enabled: false
},
series: [{
name: 'Year 1800',
data: [107]
}]
});

In HighCharts, bar graphs use inverted axes, so the bottom axis is really the Y axis. (See also "column" graphs where the graphic is rotated 90 degrees, in which case the bottom axis is the X axis.)
You need to add the following to the yAxis config
yAxis: {
labels: {
enabled: false
}
}
See the following for full example:
http://jsfiddle.net/k5yBj/433/

To hide labels on X-axis set the option labels: {enabled:false} like this:
.....
........
,
xAxis: {
categories: [''],
title: {
text: null
},
labels: {
enabled:false,//default is true
y : 20, rotation: -45, align: 'right' }
}
.....
....
To hide labels on y-axis set the option labels: {enabled:false} like this:
.....
.......
,
yAxis: {
min: 0,
gridLineWidth: 0,
title: {
text: '',
align: 'high'
},
labels:{
enabled:false//default is true
}
},
.........
......
Refer the documentation for futher understanding.

The above popular answer hides the labels only, this left tick marks for me which I also wished to remove.
In that case this works well
xAxis: {
visible: false
},
This is a simple solution to remove everything on the x/y axis for anyone interested. For more information please look here https://api.highcharts.com/highcharts/xAxis.visible

If hiding x data, then look at this
https://jsfiddle.net/anrilafosel/3g4z5kc3/
chart.xAxis[0].setCategories(newCategories);
for (i = 0; i < chart.series.length; i++) {
var newData = [];
for (j = 0; j < toggler_hc13.length; j++)
if (toggler_hc13[j] === 1)
newData.push(series_hc13[i].data[j]);
chart.series[i].setData(newData);
}
