I have a problem with amCharts after trying a lot of settings.
I want to limit the range of the y-axis from 1-150 and do not want amCharts to plot data points with the value 0. There is no time-period in the x-range. I created a fiddle of my actual result: http://jsfiddle.net/zt9exqwq/5/
var chartData = [{"position":"114","datum":"20.12.2014"},{"position":"0","datum":"24.12.2014"},{"position":"127","datum":"29.12.2014"},{"position":"128","datum":"02.01.2015"},{"position":"125","datum":"05.01.2015"},{"position":"132","datum":"09.01.2015"},{"position":"0","datum":"13.01.2015"},{"position":"131","datum":"17.01.2015"},{"position":"0","datum":"20.01.2015"},{"position":"0","datum":"24.01.2015"},{"position":"88","datum":"28.01.2015"},{"position":"89","datum":"01.02.2015"},{"position":"94","datum":"04.02.2015"},{"position":"86","datum":"08.02.2015"},{"position":"80","datum":"12.02.2015"},{"position":"83","datum":"16.02.2015"},{"position":"82","datum":"19.02.2015"},{"position":"0","datum":"23.02.2015"},{"position":"109","datum":"27.02.2015"},{"position":"100","datum":"03.03.2015"},{"position":"98","datum":"06.03.2015"},{"position":"92","datum":"10.03.2015"},{"position":"99","datum":"14.03.2015"},{"position":"97","datum":"18.03.2015"},{"position":"93","datum":"21.03.2015"},{"position":"0","datum":"25.03.2015"},{"position":"0","datum":"29.03.2015"},{"position":"108","datum":"02.04.2015"},{"position":"106","datum":"06.04.2015"},{"position":"109","datum":"10.04.2015"},{"position":"0","datum":"14.04.2015"},{"position":"107","datum":"17.04.2015"},{"position":"114","datum":"21.04.2015"},{"position":"109","datum":"25.04.2015"},{"position":"0","datum":"29.04.2015"},{"position":"111","datum":"02.05.2015"},{"position":"101","datum":"06.05.2015"},{"position":"84","datum":"10.05.2015"},{"position":"0","datum":"14.05.2015"},{"position":"74","datum":"17.05.2015"},{"position":"71","datum":"21.05.2015"},{"position":"72","datum":"25.05.2015"},{"position":"72","datum":"29.05.2015"},{"position":"0","datum":"01.06.2015"},{"position":"66","datum":"05.06.2015"},{"position":"73","datum":"09.06.2015"},{"position":"78","datum":"13.06.2015"},{"position":"72","datum":"16.06.2015"},{"position":"65","datum":"20.06.2015"},{"position":"67","datum":"24.06.2015"},{"position":"72","datum":"28.06.2015"},{"position":"74","datum":"02.07.2015"},{"position":"68","datum":"05.07.2015"},{"position":"67","datum":"09.07.2015"},{"position":"72","datum":"13.07.2015"},{"position":"74","datum":"17.07.2015"},{"position":"73","datum":"21.07.2015"}];

Here's what it actual looks like:
And here's what I want to have:
Has anybody an idea? Thanks very much.
Value axis
To set the the scale for the value axis, we can use its minimum and maximum properties. However, even if we set those two, the chart will try to round up value axis increments to "pretty" numbers, hence it will still display 0.
To work around that we will use another value axis property strictMinMax. It will ensure that our value axis scale is crisply cut at 0 and 15 values.
However we now lose the first and last labels. We'll use guides to add labels for 1 and 150 values.
Combined code for the above is this:
"valueAxes": [{
"integersOnly": true,
"maximum": 150,
"minimum": 1,
"strictMinMax": true,
"reversed": true,
"axisAlpha": 1,
"dashLength": 2,
"position": "left",
"title": "Position",
"guides": [{
"value": 1,
"label": "1"
}, {
"value": 150,
"label": "150"
}]
}]
Gaps
Zero is a valid number and a value. If you need to display a gap in place of the zero-value data points, you will need to set the value for those to null.
If you can't replace that directly in your data, you can add some custom code to iterate through the data and replace zero values with null:
for(var i = 0; i < chartData.length; i++) {
if (chartData[i].position == 0)
chartData[i].position = null;
}
In order to display gaps, we will also need to set connect: false for the graph.
And since your data is at irregular date intervals, we'll also set gapPeriod to some larger period (say 10) so that gaps are not displayed whenever you have a distance bigger than 1 day between two adjacent data points.
Here's combined working chart:
var chartData = [{"position":"114","datum":"20.12.2014"},{"position":"0","datum":"24.12.2014"},{"position":"127","datum":"29.12.2014"},{"position":"128","datum":"02.01.2015"},{"position":"125","datum":"05.01.2015"},{"position":"132","datum":"09.01.2015"},{"position":"0","datum":"13.01.2015"},{"position":"131","datum":"17.01.2015"},{"position":"0","datum":"20.01.2015"},{"position":"0","datum":"24.01.2015"},{"position":"88","datum":"28.01.2015"},{"position":"89","datum":"01.02.2015"},{"position":"94","datum":"04.02.2015"},{"position":"86","datum":"08.02.2015"},{"position":"80","datum":"12.02.2015"},{"position":"83","datum":"16.02.2015"},{"position":"82","datum":"19.02.2015"},{"position":"0","datum":"23.02.2015"},{"position":"109","datum":"27.02.2015"},{"position":"100","datum":"03.03.2015"},{"position":"98","datum":"06.03.2015"},{"position":"92","datum":"10.03.2015"},{"position":"99","datum":"14.03.2015"},{"position":"97","datum":"18.03.2015"},{"position":"93","datum":"21.03.2015"},{"position":"0","datum":"25.03.2015"},{"position":"0","datum":"29.03.2015"},{"position":"108","datum":"02.04.2015"},{"position":"106","datum":"06.04.2015"},{"position":"109","datum":"10.04.2015"},{"position":"0","datum":"14.04.2015"},{"position":"107","datum":"17.04.2015"},{"position":"114","datum":"21.04.2015"},{"position":"109","datum":"25.04.2015"},{"position":"0","datum":"29.04.2015"},{"position":"111","datum":"02.05.2015"},{"position":"101","datum":"06.05.2015"},{"position":"84","datum":"10.05.2015"},{"position":"0","datum":"14.05.2015"},{"position":"74","datum":"17.05.2015"},{"position":"71","datum":"21.05.2015"},{"position":"72","datum":"25.05.2015"},{"position":"72","datum":"29.05.2015"},{"position":"0","datum":"01.06.2015"},{"position":"66","datum":"05.06.2015"},{"position":"73","datum":"09.06.2015"},{"position":"78","datum":"13.06.2015"},{"position":"72","datum":"16.06.2015"},{"position":"65","datum":"20.06.2015"},{"position":"67","datum":"24.06.2015"},{"position":"72","datum":"28.06.2015"},{"position":"74","datum":"02.07.2015"},{"position":"68","datum":"05.07.2015"},{"position":"67","datum":"09.07.2015"},{"position":"72","datum":"13.07.2015"},{"position":"74","datum":"17.07.2015"},{"position":"73","datum":"21.07.2015"}];

I'm trying to create a hover effect for two bar at the same time, is there any possibility to achieve this by using any existing method or external css to achieve this kind of hover effect, on hover event present in highcharts I can only change the colour of the single bar image.

Here is a JSFiddle
You can make it using Highcharts.SVGRenderer which allows you to plot a rectangle and Highcharts.SVGElement.on method which allows you to add events on SVG elements (for example series group). Check demo and code posted below.
Code:
chart: {
type: 'xrange',
backgroundColor: '0C0D19',
renderTo: 'container',
marginRight: 100,
events: {
load: function() {
var chart = this,
series = chart.series[0],
seriesSvg = series.group,
seriesSvgBBox = seriesSvg.getBBox(),
width = 80,
height = seriesSvgBBox.height,
y = chart.plotTop + seriesSvgBBox.y,
x,
tooltip;
seriesSvg.on('mousemove', function(e) {
if (tooltip) {
tooltip.destroy();
}
x = e.offsetX - width / 2
tooltip = chart.renderer
.rect(x, y, width, height)
.attr({
fill: 'rgba(255, 255, 255, 0.2)'
})
.css({
'pointer-events': 'none'
})
.add()
.toFront();
});
seriesSvg.on('mouseout', function(e) {
tooltip.destroy();
tooltip = null;
});
}
}
}

I have the following code where defining a getByIds function that filters an array of objects, each of which has an id field and other fields.
// #flow
type X = {
id: string
};
type F = (Array<string>, Array<X>) => Array<X>;
import { curry } from "ramda";
const getByIds: F = curry((ids, xs) => xs.filter(x => ids.includes(x.id)));
export default getByIds;
when feeding a user = {id: 123, alias: 'foo'} to getByIds, flow warns that X doesn't have property alias . I thought flow allows extra properties (covariant?) to be attached to object of a less restricting type.

I am trying to use Data Loader from amCharts in WordPress, but I have no success. I am starting with an default Stock Chart and replacing the JS dataset structure with the one from the github site. Then I change the corresponding field values but I always get an empty site. I am using a CSV file on the same server to make sure it is not an access to external sources problem.
Does someone maybe have a complete code?

I am trying to draw a chart as below but the x axis stops at end of year 11 which it does not at the moment. I set max to 19 but it did not work.How can I get rid of those grey lines after end of Year 11?
Also for x-axis labels I want to decrease the font size of second category ([1,2,3,4]) and Year with bigger font but in label styles the font size property applies to all labels.
var l=19;
var m=-0.6;

Are m and l params constant? Or can you change them? If yes, then see: http://jsfiddle.net/TFhd7/373/
In short: Categories reserves a place from -0.5 to 0.5 with category index. For example Year7 -> 4 means x-values from 3.5 to 4.5. So according to this information let's change that values:
var l = 19.5;
var m = -0.5;
Now modify extremes and plotLines:
plotLines: [{
color: '#5DA06E',
width: 2,
value: l
}, {
color: '#5DA06E',
width: 2,
value: m
}],
max: l - 0.5,
min: m + 0.5,
i am facing quite a problem which is to create the nice graph from http://www.amcharts.com/ but i need to retrieve data from my sql database. But i don't know how to place inside. Please guide me. Below is the way how the graph displayed, but i wanted to work with data from database. Thank you.
<script type="text/javascript">
var chartData = generateChartData();
function generateChartData() {
var chartData = [];
var firstDate = new Date(2012, 0, 1);
firstDate.setDate(firstDate.getDate() - 500);
firstDate.setHours(0, 0, 0, 0);
for (var i = 0; i < 500; i++) {
var newDate = new Date(firstDate);
newDate.setDate(newDate.getDate() + i);
var value = Math.round(Math.random() * (40 + i)) + 100 + i;
chartData.push({
date: newDate,
value: value
});
}
return chartData;
}

Can you generate this script in your code behind ( using a string builder for example ) then use this
ScriptManager.RegisterStartupScript(this, this.GetType(), "", "'" + YourStringBuild.toString() + "'", true);
