Hello, 

 

I would like to highlight a GridLine based on a Labelled item when I have implemented skip in the HTML Chart. 

 

Essentially, I have a series of days and would like to step the labels on a weekly basis. At each step I would like to highlight the GridLine associated with the label.

Label position dynamic. I'm currently using "InsideBase", but if those values are so small it's not very visible, so i'd like place those on the outside end.

My objective is to compare product revenue over time. This I would like to achieve using data binding. I do not have information of product names or have the product names as columns. My data table structure is having three columns:

Date
Product Name
Revenue

This I should simply be able to achieve using data binding to a table with above three columns. 
In result I expect each of the Product Names to appear as independent series with revenues plotted on different dates.

A similar graph is displayed in the Line Chart documentation for RadHtmlChart.

I get a lot of work creating BI/KPI UIs which are basically converting what you can do in Excel Charts into a Web UI.   Which means anything they can do in Excel they expect the web to do. 
Since there is a drive to automate as much mundane human activity in the business and reduce human error (cut and paste error). 
I need to reproduce a graph with 'standard' Tend Lines. 
That is not my interpretation of a trend, but standard best practice.
I want this as a checkbox, and attribute to a series for the DataFieldY value.
Initially a code solution would be fine (once its got the data from the data source).

Currently, the RadHtmlChart control allows you to create a spline series to display. But sometimes, we need the curve to follow more of a Bezier path because the points in the series aren't necessarily the local min/max for the neighborhood around them. This would function much like the smooth line that appears in Excel's scatter chart type or the ChartFX control's curve gallery type.

I would like to request a new feature in legend of RadHtmlChart that provide a tool-tip for long names because when I add a long text in legends the size of pie-chart is reduced. 
Sample code for what I expect to be working :

<telerik:RadHtmlChart runat="server" ID="Chart" Height="400px" Width="400px">
<ClientEvents OnLoad="onChartLoad" />
function onChartLoad()
{
var chart = $find("Chart");
var widget = chart.get_kendoWidget();
widget.options.legend.tooltip = "#: dataItem.columnname #" //Feature Request in this line
widget.redraw();
}

Hello,
Like a lot of companies we have multiple client side interfaces of a single application and have to create similar UI in multiple platforms.
For example I had to create a chart in both WPF and ASP.NET AJAX today.
The problem I have with the Telerik controls is that there are absolutely no standardization or consistency between platforms.
Why would a Cartesian Axis in WPF and ASP.NET AJAX and ASP MVC and Windows Universal Apps not all called the same thing?
It would be very simple to use interfaces to create some consistency between platforms.
Even better would be if Model Views are shared across platforms in a portable library:

Add support for a secondary x-axis at the top of the chart.
Please use consistent axis types.
Why would the primary axes be of type Telerik.Web.UI.HtmlChart.PlotArea.Chart*Axis and the secondary y-axis be of type Telerik.Web.UI.AxisY?

Right now we do not have a way to show some tooltips over Axis Labels
This is useful when we have big names for Axis Labels, we can put some short cut names be default and then show full name over tool tip.

We can use Series tooltip, but it looks ugly for stacked series when you have 4 to 5 series

When migrating from a GeckoBoard.com dashboard, I have a Area Chart where the values over the target are one colour and those below another colour, this is true of Area and Bar charts. At the moment  I can use the "'ColorField="ErrorsColor"> " to colour the whole column to a given colour, but not that part above its Target.
One approach could be is to have 2 plots one below the target and one above the target, I would prefer to be this in control of the HtmlChart and for me not to frig it.
Thanks

Hi,

What I see in the HTML chart control is almost what I need.  The closest that I can get to a "generic chart" (with everything specified in the data) is binding to the XMLDataSource, but even with that, it appears that the Series Name needs to be hard-coded (not included in the XML data) or we need to write code to replace a hard-coded value with an "out of band" supplied value for each of the series names.

I've been looking through all of the demos and it appears that in every one of them, labels or titles that appear on the graph show up in the code somewhere.  Then when I look at the documentation, there is no place where those labels or titles can be extracted from the data source.  This would indicate to me that every graph needs to be hard-coded.

Am I missing something?  I hope so.  We have potentially thousands of graphing possibilities that we need to implement and would like the user to be able to design their own and this control looks pretty good, except for the "hard-coding" thing.  If we could retrieve the series names from the XML input, the task would take days; if we need to individually code each chart, it will take months to staff-years.

Here is a sample of what the XML input could look like:

<chart caption='Error Summary by Day'>
	<categories>
		<category label='Nov+11' />
		<category label='Nov+12' />
		<category label='Nov+13' />
		<category label='Nov+14' />
		<category label='Nov+15' />
		<category label='Nov+16' />
		<category label='Nov+17' />
		<category label='Nov+18' />
		<category label='Nov+19' />
		<category label='Nov+20' />
		<category label='Nov+21' />
		<category label='Nov+22' />
		<category label='Nov+23' />
		<category label='Nov+24' />
		<category label='Nov+25' />
		<category label='Nov+26' />
		<category label='Nov+27' />
		<category label='Nov+28' />
		<category label='Nov+29' />
		<category label='Nov+30' />
	</categories>
	<dataset seriesname='Notes'>
		<set value='0' />
		<set value='0' />
		<set value='0' />
		<set value='3' />
		<set value='3' />
		<set value='4' />
		<set value='5' />
		<set value='5' />
		<set value='3' />
		<set value='3' />
		<set value='2' />

		<set value='0' />
		<set value='0' />

	</dataset>
	<dataset seriesname='Warnings'>

		<set value='3' />
		<set value='2' />

		<set value='74' />
		<set value='74' />
		<set value='74' />
		<set value='76' />
		<set value='76' />
		<set value='76' />
		<set value='71' />
		<set value='71' />
		<set value='64' />
		<set value='64' />
		<set value='64' />
		<set value='54' />
		<set value='44' />
		<set value='44' />
		<set value='31' />
		<set value='31' />
		<set value='21' />
		<set value='22' />
		<set value='12' />
	</dataset>
</chart>

You would use an XML attribute to specify series and chart names.

Thanks,
Rob

In RadHtmlChart there is no property to specify Width for Bar/Column series. It automatically calculates series width based on chart width, number of series, number of items within series, gap and spacing, etc.,
If there is more than one bar/column chart in single page, there is no way to show Bar/Column series of exact width in all chart to make page consistent.

For the time being you can use a JavaScript function inside the template to cut the labels - http://docs.telerik.com/kendo-ui/dataviz/chart/how-to/shorten-chart-labels
