AmCharts - graphs connected by starting and ending points - javascript

I have multiple graphs per chart and for some unknown(to me) reason each graph is connected by the start and the end points of it e.g.
Simple question: How to remove it? I couldn't find anything in the documentation that controls it.
My code as follows:
lineChart = function(id, period) {
var chart, data = [];
var cData = chartData[id];
AmCharts.ready(function() {
for (item in cData) {
var i = cData[item];
data.push({
date: new Date(i.date),
impressions: i.impressions,
clicks: i.clicks,
conversions: i.conversions,
ctr: i.ctr,
profit: i.profit,
cost: i.cost,
revenue: i.revenue
});
}
chart = new AmCharts.AmSerialChart();
chart.dataProvider = data;
chart.categoryField = "date";
chart.balloon.color = "#000000";
// AXES
// category
var categoryAxis = chart.categoryAxis;
categoryAxis.fillAlpha = 1;
categoryAxis.fillColor = "#FAFAFA";
categoryAxis.gridAlpha = 0;
categoryAxis.axisAlpha = 0;
categoryAxis.minPeriod = period;
categoryAxis.parseDates = true;
categoryAxis.gridPosition = "start";
categoryAxis.position = "bottom";
// value
var valueAxis = new AmCharts.ValueAxis();
valueAxis.dashLength = 5;
valueAxis.axisAlpha = 0;
valueAxis.integersOnly = true;
valueAxis.gridCount = 10;
chart.addValueAxis(valueAxis);
// GRAPHS
// Impressions graph
var graph = new AmCharts.AmGraph();
graph.title = "Impressions";
graph.valueField = "impressions";
graph.balloonText = "[[title]]: [[value]]";
//graph.lineAlpha = 1;
graph.bullet = "round";
chart.addGraph(graph);
// Clicks graph
var graph = new AmCharts.AmGraph();
graph.title = "Clicks";
graph.valueField = "clicks";
graph.balloonText = "[[title]]: [[value]]";
graph.bullet = "round";
chart.addGraph(graph);
// Conversions graph
var graph = new AmCharts.AmGraph();
graph.title = "Conversion";
graph.valueField = "conversions";
graph.balloonText = "[[title]]: [[value]]";
graph.bullet = "round";
chart.addGraph(graph);
// LEGEND
var legend = new AmCharts.AmLegend();
legend.markerType = "circle";
chart.addLegend(legend);
var chartCursor = new AmCharts.ChartCursor();
chartCursor.cursorPosition = "mouse";
if(period == 'hh')
chartCursor.categoryBalloonDateFormat = "MMM DD, JJ:00";
chart.addChartCursor(chartCursor);
// WRITE
chart.write(id);
});
};

This looks like the data issue. Make sure your data points are strictly in consecutive ascending order.
To verify how your actual data looks like, add the second line below to your code. Then run your chart in Google Chrome with Console open (F12 then select Console tab)
chart.dataProvider = data;
console.debug(data);
Check the datapoints for irregularities. Especially the last two ones.

The problem was that each chart was rendered within it's own AmCharts.ready method. The documentation states that it's allowed, however it didn't work for me, therefore I wrapped all rendering within one ready method and the issue was fixed.

AM charts display fixed range in axes

Really Hope you can help!
I am using AMCharts and Ive added some data through a simple php function (pulled from database)
I've added some upper and lower limits, using the below function
// HORIZONTAL GREEN RANGE
var guide = new AmCharts.Guide();
guide.value =11.00;
guide.toValue = 11.80;
guide.fillColor = "#00CC00";
guide.inside = true;
guide.fillAlpha = 0.2;
guide.lineAlpha = 0;
valueAxis.addGuide(guide);
var guideRED = new AmCharts.Guide();
guideRED.value = 11.80;
guideRED.toValue = 11.90;
guideRED.fillColor = "orange";
guideRED.inside = true;
guideRED.fillAlpha = 0.2;
guideRED.lineAlpha = 0;
valueAxis.addGuide(guideRED);
var guideblue = new AmCharts.Guide();
guideblue.value = 11.00;
guideblue.toValue = 10.90;
guideblue.fillColor = "orange";
guideblue.inside = true;
guideblue.fillAlpha = 0.2;
guideblue.lineAlpha = 0;
valueAxis.addGuide(guideblue);
but I need to set the display range on the Y (top to bottom???) to 11.90 and 10.50 respectivly so the operator can see the plotted line, and its relationship to the red and orange zones. At present the graph simply renders the chart to +1 the max and min it has in value form.
Here is the graph functions
AmCharts.ready(function () {
// SERIAL CHART
chart = new AmCharts.AmSerialChart();
chart.dataProvider = chartData;
chart.dataDateFormat = "DD-MM-YY";
chart.categoryField = "date";
// AXES
// category
var categoryAxis = chart.categoryAxis;
// categoryAxis.parseDates = true; // as our data is date-based, we set parseDates to true
// categoryAxis.minPeriod = "DD"; // our data is daily, so we set minPeriod to DD
categoryAxis.gridAlpha = 0.1;
categoryAxis.minorGridAlpha = 0.1;
categoryAxis.axisAlpha = 0;
categoryAxis.minorGridEnabled = true;
categoryAxis.inside = true;
// value
var valueAxis = new AmCharts.ValueAxis();
valueAxis.tickLength = 4;
valueAxis.axisAlpha = 0;
valueAxis.showFirstLabel = false;
valueAxis.showLastLabel = false;
valueAxis.autoGridCount = true;
valueAxis.gridCount = 500;
chart.addValueAxis(valueAxis);
// GRAPH
var graph = new AmCharts.AmGraph();
graph.dashLength = 2;
graph.lineColor = "#00CC00";
graph.valueField = "value";
graph.dashLength = 3;
graph.bullet = "round";
graph.balloonText = "[[category]]<br><b><span style=\'font-size:14px;\'>value:[[value]]</span></b>";
chart.addGraph(graph);
(this is all within a tag hence the escape char's
Many thanks.
To force the value axis to particular scale, first set it's minimum and maximum properties. The chart will still try to use whole numbers. To disable that set strictMinMax.
I.e.:
var valueAxis = new AmCharts.ValueAxis();
valueAxis.minimum = 10.5;
valueAxis.maximum = 11.90;
valueAxis.strictMinMax = true;

AMCharts How to color bullets by value?

I am working with amcharts and I tried to color bullets in the chart by the values they have. So I created an array in javascript and passed the values from the database into it. Green is just a value for testing.
var chartData = [
<?php
foreach($tmp as $row)
{
echo'{"Wahrscheinlichkeit":'.$row[3].',"Schaden":'.$row[4].',"value":1,"Beschreibung":"'.$row[2].'", "Color":"Green"},';
}
?>
];
Here I create the chart:
chart = new AmCharts.AmXYChart();
chart.dataProvider = chartData;
Here I draw the chart:
var graph = new AmCharts.AmGraph();
graph.valueField = "value"; // größe der Kugeln
graph.xField = "Wahrscheinlichkeit";
graph.yField = "Schaden";
graph.maxBulletSize=20;
graph.lineAlpha = 0;
graph.bullet = "circle";
graph.bulletColor= "[[Color]]";
graph.balloonText = "Wahrscheinlichkeit:<b>[[x]]</b> Schaden:<b>[[y]]</b><br>Beschreibung:<b> [[Beschreibung]]</b>"
chart.addGraph(graph);
At the point "bulletcolor" I try to get the color out of the array, but it doesn't work.
chart.write("chartdiv");
Looking forward getting tips and help from you
"bulletColor" can't reference fields in data like this.
Instead, please use "lineColorField":
http://docs.amcharts.com/3/javascriptcharts/AmGraph#lineColorField
I.e.:
var graph = new AmCharts.AmGraph();
graph.valueField = "value"; // größe der Kugeln
graph.xField = "Wahrscheinlichkeit";
graph.yField = "Schaden";
graph.maxBulletSize=20;
graph.lineAlpha = 0;
graph.bullet = "circle";
graph.lineColorField = "Color";
graph.balloonText = "Wahrscheinlichkeit:<b>[[x]]</b> Schaden:<b>[[y]]</b><br>Beschreibung:<b> [[Beschreibung]]</b>"
chart.addGraph(graph);

amcharts showing value inside bar

I'm using amCharts, and i want to show values inside bar
This is how it looks at the moment:
and I want it to be like this:
This is my code to display chart:
AmCharts.ready(function() {
generateWidgetData('week');
// SERIAL CHART
chart = new AmCharts.AmSerialChart();
chart.dataProvider = graphData;
chart.categoryField = 'date';
chart.startDuration = 1;
chart.columnWidth = 0.60;
chart.dataDateFormat = 'YYYY-MM-DD';
chart.startEffect = 'easeInSine';
chart.stackType = 'regular';
// AXES
// category
var categoryAxis = chart.categoryAxis;
categoryAxis.parseDates = true;
categoryAxis.minPeriod = 'DD';
categoryAxis.plotAreaBorderAlpha = 0.01;
categoryAxis.labelRotation = 90;
categoryAxis.axisThickness = 0;
categoryAxis.stackType = 'regular';
categoryAxis.gridThickness = 0;
categoryAxis.inside = false;
//categoryAxis.gridPosition = 'start';
//categoryAxis.startDate = '2014-05-08';
// value
// in case you don't want to change default settings of value axis,
// you don't need to create it, as one value axis is created automatically.
// GRAPH
var graph = new AmCharts.AmGraph();
graph.maxColumns = 1;
graph.valueField = 'Self-entered';
graph.balloonText = '[[category]]: <b>[[value]]</b>';
graph.type = 'column';
graph.lineAlpha = 0;
graph.labelText = '[[value]]';
graph.fillAlphas = 0.8;
graph.stackType = 'regular';
chart.addGraph(graph);
graph.cornerRadiusTop = 8;
// CURSOR
var chartCursor = new AmCharts.ChartCursor();
chartCursor.cursorAlpha = 0;
chartCursor.zoomable = false;
chartCursor.categoryBalloonEnabled = false;
chart.addChartCursor(chartCursor);
chart.creditsPosition = 'top-right';
chart.write('stepschart');
});
Thanks in advance.
I fixed this so i will post answer, maybe it will help to someone
its really simple all you need to do is to add 2 lines of code:
graph.labelText = '[[value]]'; // this will insert values in labels
graph.labelPosition = 'inside'; // and with this we put our label inside bar
Hope this will help to someone who also need to do same thing

AmCharts Smoothed Line Serial Multiple Y Axis is not Showing

I try to make multiple line using amcharts. The type I'm gonna use is smoothed lines (view demo here). I've seen it's possible to draw multiple line charts and multiple value axis on this link. So, I try to implement it on smoothed lines using:
a. 2 lines
b. Both of them are different in scale, so I need two Y axis.
The problem is: only one Y axis appears.
Here's the code I wrote using javascript:

Anyone having similar issues? How to overcome this?
It's all very simple, you have a typo:
graph.valueaxis should be graph.valueAxis
