I'm using CanvasJS to display some weather data, but the labels seem to have the wrong position relative to their data point.
What is the cause of this?
This is my chart configuration:
animationEnabled: true,
exportEnabled: true,
title: {
text: 'Pronóstico 8 Días',
},
axisX: {
valueFormatString: 'DD MMM,YYYY',
labelAngle: -30,
labelPlacement: 'outside',
labelTextAlign: 'left',
},
axisY: {
title: 'Temperatura',
suffix: ' °C',
minimum: 18,
maximum: 40,
interval: 2,
},
data: [
{
name: 'Mínimas',
type: 'line',
yValueFormatString: '#0.## °C',
showInLegend: true,
indexLabelWrap: true,
indexLabelMaxWidth: 80,
dataPoints: min,
},
{
name: 'Máximas',
type: 'line',
yValueFormatString: '#0.## °C',
showInLegend: true,
indexLabelWrap: true,
indexLabelMaxWidth: 80,
dataPoints: max,
},
],
The issue was the dates were shifting because they included time, so I just turned into day/month/year only.

I have MVC app, it's a Tab Panel containing few Tabs with a chart on each, there is also a Date Picker with Refresh button, and a Combo box to choose which data source is being used for the 'Date Range'.
The app currently loads the charts with all available data but the purpose is to select 1 of 3 available data sources, select a date range and refresh every chart tab by clicking a button, how do I do it?

I have a multiselect dropDownList and a chart,i want my chart to by dynamic to plot more based on my multiselect dropdownlist,but i have no idea, I would appreciate if you give me a hint by a demo or an example.because in the following code,i have a chart which works only based normal dropdownlist not the multiplechioce,
Here is Multiselect:
$('#multiselect').kendoMultiSelect({
dataTextField: "Text",
dataValueField: "Text",
valuePrimitive: true,
dataSource: result.list_of_parks,
})
here is the chart:
function createChart(data, data_wind) {
$("#topMonth").kendoChart({
series: [{
data: data,
type: "column",
axis: "l100km",
field: "productionvalue",
categoryField: "name",
color: "#228B22"
},
{
axis: "ava",
data: data_wind,
type: "line",
field: "windvalue",
categoryField: "name",
color: "#007eff",
},
],
valueAxes: [
{
name: "l100km",
title: { text: "Production (MW/H)" },
// min: 0,
// max: 2000000,
// majorUnit: 200000,
majorGridLines: {
visible: false
},
minorGridLines: {
visible: false
},
},
{
name: "ava",
title: { text: "Averge Wind Speed(KM/H)" },
min: 0,
// max: 20,
majorUnit: 1,
majorGridLines: {
visible: false
},
minorGridLines: {
visible: false
},
}
],
categoryAxis: {
majorGridLines: {
visible: false
}
,
labels: {
padding: {
left: -20,
buttom: 0
},
rotation: 340
},
axisCrossingValues: [0, 20],
},
tooltip: {
visible: true,
// majorUnit:10,
template: " #= value #"
},
});
$(window).on("resize", function () {
kendo.resize($(".chart-wrapper"));
});
}
}
});
});
I'm creating a grouped bar chart like this:
$("#chart").kendoChart({
dataSource: {
data: rawdata,
group: { field: "Serie" },
},
legend: {
position: "top"
},
plotArea: {
background: "white",
},
seriesDefaults: {
type: "column",
style: "smooth",
stack: true
},
series: [
{
field: 'Valor1',
labels: {
visible: true,
background: '',
format: 'p1',
color: 'white',
position: 'center'
},
}
],
valueAxis: {
max: 1,
labels: {
format: "p2"
},
line: {
visible: false
},
axisCrossingValue: -10,
},
categoryAxis: {
field: "Segmento",
majorGridLines: {
visible: false
}
},
tooltip: {
visible: true,
template: "#= series.name # <br /> " +
"Valor = #= kendo.format('{0:p2}', value) # <br/> " +
"Tooltip = #= dataItem.Tooltip # ",
}
});
My data has four properties: Serie, Segmento, Valor1, Tooltip. Example of one data point:
{
"Serie": "S1",
"Segmento": "C1",
"Valor1": 0.31500380634422465,
"Tooltip": 20,
}
The values of the stack bar are incorrect in chrome but in firefox and ie it's fine.
Correct graph in firefox and ie:
Incorrect graph in chrome:
Here is a live demo: http://trykendoui.telerik.com/anET/9
How can i solve this?
This is a problem with Chrome's implementation of Array.sort; see this discussion.
You can fix it by sorting the data source explicitly:
dataSource: {
data: rawdata,
group: { field: "Serie" },
sort: [{ field: "Serie", dir: "asc"}, { field: "Segmento", dir: "asc"} ]
},
(updated demo)
In Extension grid paging and filtering is not working..please help me out.In this code if i replace store with simplestore and ds.load() with ds.loadData(mydata) then simple grid is working but paging is not working.but i have seen some samples according to these i have converted my code..but after that its not working at all.
Ext.onReady(function () {
