I'm using jqplot for displaying bar chart and pie chart. I want to display them without grid lines. So, I've inserted the following line.
grid:{background:'transparent',borderColor:'#d0d0d0'},
It is not working in IE but in firefox it is displaying without grid lines. Please help me out.
The grid lines can also be removed using the showGridline property within the tickOptions object (within the x or y axis object [within the axes object {within the options object}]).
axes: {
xaxis: {
tickOptions: {
showGridline: false
}
}
}
I'm pretty sur that IE < 9 doesn't support transparancy.
Try this for IE <= 8 loading of excanvas, It worked for me:
<!--[if lt IE 9]><script language="javascript" type="text/javascript" src="../src/excanvas.js">
</script><![endif]-->
grid: { background: 'rgba(0,0,0,0)',
drawBorder: false,
shadow: false
}

I need some help with how Kendo Chart tool.
I am trying to plot a line graph with bookings on particular date. I have a booking on a particular day and can see the circular plot. If i hover on it i can see the tool tip which contains the summary of the booking. I want this tooltip to always be visible/open. At the moment it only happens on mouse over.
function createChart() {
$("#chart").kendoChart(data);
var tooltip = $("#chart").kendoTooltip({
width: 120,
position: "top",
visibe: true
}).data("kendoTooltip");
}
I am using Kendo for the first time and am very confused now. Any help will be much appreciated.
You can always show the tooltips or labels without having to hover over them by mouse, by using setting the visible of the series labels to true as follows:
seriesDefaults: {
type: "line",
labels: {
visible: true
}
}
You can check and see a demo example here: http://demos.telerik.com/kendo-ui/line-charts/local-data-binding
I have kendo MVC Grid and I have to set my page size to 50, so I need to freeze the column header while scrolling.
The question is : How can I freeze the column header while scrolling ?
When you create the Grid you should define the height in pixels as well as define scrollable as true.
Example:
var grid = $("#grid").kendoGrid({
dataSource: ds,
scrollable: true,
height : "150px",
columns : [
...
]
});
See this working here : http://jsfiddle.net/OnaBai/uuPW5/
Maybe this is something you were looking for:
https://github.com/jmosbech/StickyTableHeaders
Works quite well and you don't have to have scrollbars in your grid which makes it easier to work with.
You simply link provided script to your view and call this method on load:
$('#grid').stickyTableHeaders({
cacheHeaderHeight: true,
leftOffset: 1,
fixedOffset: ...
});
Parameters are optional but cacheHeaderHeight improves performance and I had to add leftOffset because of custom grid header borders and fixedOffset because of other sticky elements.
Just set the css of the grid header like this :
.k-grid-header {
position: sticky;
top: 0;
}
This answer has already been given for kendo UI, but here is how it's implemented for kendo MVC:
.Scrollable(scr => scr.Height(400))
It will give you a vertical scroll bar, allowing the user to scroll through the data while constantly seeing both the header and footer of the table. You can read more about it here: https://docs.telerik.com/aspnet-mvc/html-helpers/data-management/grid/scrolling/overview.
Trouble with this solution, however, is that the grid will be 400px tall, even when there is only one row of data. You can solve this like so
.Scrollable(scr =>
{
if (data.Count() < 10)
{
scr.Height("auto");
}
else
{
scr.Height(400);
}
})
I have jqplot donut chart where I want to add chart labels in the center part. Also want to add scrolling for labels in the middle of graph. So only 1-2 labels in the center will be visible and rest will be visible when user scrolls.
Please have a look attached image. As per my knowledge, we can't add labels in the center of chart. Is there any way to do this? Appreciate your help.
My current code is as below:
<script type="text/javascript">
var _chart5_plot_properties;
_chart5_plot_properties = {
title: " ",
"seriesDefaults":{
renderer:$.jqplot.DonutRenderer,
rendererOptions:{
sliceMargin: 0,
innerDiameter: 220,
startAngle: -90,
barPadding: 0,
padding: 3,
}
},
grid: {
shadow: false,
drawBorder: false,
shadowColor: "transparent"
},
highlighter: {
show: true,
tooltipLocation: "sw",
useAxesFormatters:false
}
}
plot2 = $.jqplot("chart2", chart_data, _chart5_plot_properties);
I couldn't find an option for this in jqPlot.
Though, jqPlot has 8 options to position the legend, but it does not have the center option. jqPlot Legend Locations
But after tweaking it a bit, I could accomplish it using jQuery. Since we need to require jQuery to render/draw jqPlot charts, so I thought of using jQuery rather than pure Javascript.
I have used two functions defineDimensionsForLegendTable(parentContainerID, dimensions) and fixLegendsToCenter(parentContainerID)
Other important things that you should not miss out while using these functions
Make sure you include the jquery.jqplot.js, jqplot.pieRenderer.js, jqplot.donutRenderer.js, jquery.jqplot.css files (or the minified versions - .min.js)
Set placement to outsideGrid in legendOptions
legend: { show:true, placement: 'outsideGrid' }
Give a higher z-index to the legend-table
#chart2 .jqplot-table-legend{
z-index: 99999;
}
Find the working fiddle here - jqPlot Donut Chart with legend in the center
Note: If the chart does not show up in Google Chrome, try opening it in Firefox or some other browser.
Remove the console.log lines from the code ;-)
You can use Foundation or Bootstrap to beautify the scrollbar. :-)
Hope it helps :-)
Following the Telerik Kendo Area Chart example found here: http://demos.telerik.com/kendo-ui/dataviz/area-charts/index.html
I've been trying to apply the 'smooth' effect to my chart, but with no luck.
seriesDefaults: {
type: "area",
stack:false,
area: {
line: {
style: "smooth"
}
}
},
Maybe I'm going blind, but I can't see what's wrong.. I've tried a myriad of different options and included all of the css styles for example in the jsFiddle:
http://jsfiddle.net/markive/u33m6/
Any idea what I am doing wrong?
I have a jqplot object that has x-axis tick marks/labels rendered on bottom. Basically, there is a stack of charts, all using the same x-axis. I would like to reclaim the bottom axis area from the middle charts for the plot lines.
How can I dynamically relocate the x-axis to top (i.e., northward)
How to make the x-axis label go away? For this I tried
plotobject.axes.xaxis.showLabel = false;
plotobject.replot();
but that seems to have no visible effect. plotobject is what's returned by the original $.jqplot() call and I am using $.jqplot.DateAxisRenderer for xaxis.renderer. I have access only to the plot object.
Thanks
This simple CSS solution is working for me to put the x-axis labels on top of the chart.
.jqplot-xaxis {
position: relative;
top: -30px;
}
well, the label for each axis (which is the axis title) has it's own renderer, and thus it's own options. I use the plugin one ( http://www.jqplot.com/docs/files/plugins/jqplot-canvasAxisLabelRenderer-js.html ) but also the default has a show: true/false setting. ( http://www.jqplot.com/docs/files/jqplot-axisLabelRenderer-js.html )
it should look something like this:
axes: {
xaxis: {
labelRenderer: $.jqplot.CanvasAxisLabelRenderer,
label: 'Dates',
labelOptions: {
show: true,
fontSize: '10pt'
},
}
}
For putting the x-axis on top, I'm not sure what your problem realy is, but I try to select it with jquery and set it's z-index to something high to bring it on top. Take a look at http://www.jqplot.com/docs/files/jqPlotCssStyling-txt.html for some selection ideas.
