JQPlot displays stacked bars horizontal wrong - javascript

I have a problem correctly displaying JQPlot stacked bars horizontal.

// Bind a listener to the "jqplotDataClick" event. Here, simply change

Sorry that I can't post an image but I don't have enough reputation.

Thank you, but I get solved it another way.
Here ist my code:
axes: {
xaxis: {
renderer: $.jqplot.CategoryAxisRenderer
},
yaxis: {
// Don't pad out the bottom of the data range. By default,
// axes scaled as if data extended 10% above and below the
// actual range to prevent data points right on grid boundaries.
// Don't want to do that here.
padMin: 0
}
},
Change this in this:
axes: {
yaxis: {
renderer: $.jqplot.CategoryAxisRenderer
}
},
so it works ;)

Highcharts doesn't plot series with lots of data

I trying to get highcharts to draw a linked graph. It works when I have not so much data in my data set. Now I have tried to put a dataset with ~30.000 points. I see the mouse over with the points, but the line is not plot?
I have read about turboThreshold: and have set it to turboThreshold: 40000 but it does still not plot the line??
Any ideas what I do wrong?

I have this issue before but my X-Axis values was numbers and fixed it by adding ratio (Adjustment) about 20% from the max value to just gain more space and that did the trick Here I recommend you to add one more value in the X Values(X Ticks) without a related Value in the Y Values (ticks) to extend (add more space) the X Axis (if you have the same issue with Y Axis use the same technique) Have a look Here on Plunker

Hope this help.

You need to enable highlighter with this code in your target.jqplot(dataPlot, {...}) call...
highlighter: {
show: true,
sizeAdjust: 7.5
},
Use this CSS to style your tooltip ;)
.jqplot-highlighter-tooltip {
background: #fff;
box-shadow: 0 0 3px 1px rgba(0,0,0,0.5);
padding: 2px 3px;
}
Hope that helps ;)

I was facing a similar issue with the data labels not displaying at the edge of my trends.
One solution is to increase the edgeTolerance in the jqplot.pointLabels.js file from the default (-10) to the desired value:
$.jqplot.PointLabels = function(options) {
...
// prop: edgeTolerance
// Number of pixels that the label must be away from an axis
// boundary in order to be drawn. Negative values will allow overlap
// with the grid boundaries.
this.edgeTolerance = -1000;
...
$.extend(true, this, options);
};

Display bar chat in jqplot in a specific color for a particular range values

I tried this code for changing the color of -260 range value, but it is not working. For this i used the scripts :
<script type="text/javascript" src="../js/jqplot/jquery.min.js"></script>
<script type="text/javascript" src="../js/jqplot/jquery.jqplot.min.js"></script>
<script type="text/javascript" src="../js/jqplot/jqplot.categoryAxisRenderer.min.js "></script>
<script type="text/javascript" src="../js/jqplot/jqplot.barRenderer.min.js"></script>
<link rel="stylesheet" type="text/css" href="./css/jquery.jqplot.min.css" />
This is the render script that i used to change the color. In this script, $.jqplot.ColorGenerator is not working properly.
<script>
var s1 = [460, -260, 690, 820];
$(document).ready(function() {
// Can specify a custom tick Array.
// Ticks should match up one for each y value (category) in the series.
var ticks = ['May', 'June', 'July', 'August'];
$.jqplot.ColorGenerator = function(P) {
if (this.idx == null)
this.idx = -1; // keep track of our idx
this.next = function()
{
this.idx++; // get the next color
if (s1[this.idx] < -200) // is the value in our data less 200
return 'red';
else
return 'blue';
}
this.get = function() // this is not used but it needed to be defined
{
return 'blue';
}
}
var plot1 = $.jqplot('chart1', [s1], {
animate: true,
animateReplot: true,
// The "seriesDefaults" option is an options object that will
// be applied to all series in the chart.
seriesDefaults:{
renderer:$.jqplot.BarRenderer,
rendererOptions: {fillToZero: true,
animation: {speed: 2500},
varyBarColor: true,
useNegativeColors: false
}
},
// Custom labels for the series are specified with the "label"
// option on the series option. Here a series option object
// is specified for each series.
series:[
{label:'Hotel'},
{label:'Event Regristration'},
{label:'Airfare'}
],
// Show the legend and put it outside the grid, but inside the
// plot container, shrinking the grid to accomodate the legend.
// A value of "outside" would not shrink the grid and allow
// the legend to overflow the container.
legend: {
show: true,
placement: 'outsideGrid'
},
axes: {
// Use a category axis on the x axis and use our custom ticks.
xaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
ticks: ticks
},
// Pad the y axis just a little so bars can get close to, but
// not touch, the grid boundaries. 1.2 is the default padding.
yaxis: {
pad: 1.05,
tickOptions: {formatString: '$%d'}
}
},
highlighter: {
show: true,
sizeAdjust: 7.5
},
cursor: {
show: false
},
canvasOverlay: {
show: true,

Flot returns incorrect x value (mm/dd/yy - date) after zoom for stack bar chart

I want to get the correct x axis label when user zooms the chart and click on a specific bar
when clicking on the bar on (02/14/14 - xaxis) the alert shows the (02/19/14 - xaxis) label.
It returns the correct date when the zoom(selection) is not firing. but after zooming the chart and clicking on the bar it populate a wrong date.
I am new to flot charts. please help me. thanks.

The problem is this line of code:
var tickClicked = item.series.xaxis.ticks[item.dataIndex+1].label;
When your plot is unzoomed you have one tick per datapoint (bar). When you zoom, however, you end up with in between ticks, so the finding a tick by item.dataIndex isn't going to work.
I'm guessing you care more about the data associated to the bar (and not really the tick) so get the bar x value and format it back to a date string.
var tickClicked = $.plot.formatDate(new Date(item.datapoint[0]),"%m/%d/%Y");
EDITS
Instead of making another .plot call on zoom redraw the chart with (this is how I do it in my applications using flot):
var opts = plot.getOptions();
opts.xaxes[0].min = ranges.xaxis.from;
opts.xaxes[0].max = ranges.xaxis.to;
opts.yaxes[0].min = ranges.yaxis.from;
opts.yaxes[0].max = ranges.yaxis.to;
plot.setupGrid();
plot.draw();

HighCharts - Getting chart to display - Simple example (markit API)

I am new to programming with JavaScript and am having some troubles implementing a HighCharts chart. The API I am using is markit (https://github.com/markitondemand/DataApis/blob/master/MarkitTimeseriesServiceSample.js) to produce a chart as shown halfway down this page http://dev.markitondemand.com/
Now I thought I had to add that js script in place of the js shown in this fiddle (http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/line-basic/) but it doesn't seem to be working.
I think it may be because I am not assigning where I actually want to put it but I am not 100% sure.
Please see below for my code:

Thanks a lot for the help.

In your <div> change the id to #chartDemoContainer
Replace your jQuery libraries with these,
