What's required:
Heatmap charts by Dojo to show data in 2-D chart as colored cells for MVC.NET project.
Eg., Something similar to these Plotly heatmaps
Platform: IE
Features: Annotations, Zooming, Interactive, text rotation for labels, dynamic chart.
What's researched:
Dojo ticket 11705 asking for Heatmap. But was closed as 'wontfix'.
Found a patch intermediately shared for above ticket. But, it did not work.
If the Heatmaps are not currently supported, are there future plans to include it?
AFAIK there is no a heat-map chart ready made in dojo, but you could develop you own combining its functionalities.

I would like to know if there is anyway to add a tool-tip while hovering over an annotation or a drawing using stock charts i anychart.
for example, if i draw a rectangle, i would like to show a tool-tip to with the values of the rectangle(start and end dates, and upper and lower price).
if there aren't any built-in functions to do so, are there any event listeners for hovering over an annotation? then maybe when the event of hovering the mouse-in i could create an html element and then hide it on the even of mouse-out.
another solution might be by creating labels on the xAxis and on the yAxis. but i could not find anything to add labels in a specific location.
any suggestion is appreciated.
Unfortunately, the current version of the library 8.7.0 doesn't support tooltip or events to implement custom interactivity with Stock chart annotations.
If you want to add labels on the axes, you can use text axis markers. The article is about basic charts, but it will work for Stock charts. The difference is that you should call API not from a chart, but from Stock chart plot.
For example chart.textMarker() should be replaced with chart.plot(0).textMarker(), and that's it.
Is it possible to hide the markers on an "xyscatterLines" chart like on EXCEL desktop version ? (like illustrate on images below).
After much research, I found the solution. It is to use the "xyscatterLinesNoMarkers" chart type.
"Smart Labels" are labels that do not overlap each other.
They are mentioned in the docs: http://docs.telerik.com/devtools/wpf/controls/radchartview/features/labels/smart-labels
My question is about "Smart Labels", which is a Telerik UI feature we decided to use. I need to mirror Telerik UI Charts functionality using Kendo UI Charts and thus "Smart Labels" is a requirement.
Unfortunately, there is no such feature in Kendo UI Charts. You can find a thread relating to this in the Telerik forums.
Basically what the Telerik representative says is that the feature isn't available and suggests several other solutions:
Use categoryAxis.labels.step / categoryAxis.labels.skip options and display only some of the labels
Use a categoryAxis.labels.template and trim the labels to a specific length
Another user preferred making the labels invisible altogether.
We're using Rational Team Concert to manage our projects (specifically, we're using IBM Bluemix DevOps Services, which backends to Rational Team Concert). We'd like to create some useful charts of incoming defects and the evolution of the number of work items in our project, but the charts that the RTC dashboard produces are, frankly, bad. The colors are poor and the graphical style employed makes the charts look as though they were drawn with markers designed for toddlers.
Aside from the fact that neither of these graphs has any interactivity or utilizes the full available width of their container on the dashboard, there's the fact that the X-axis on both charts is completely unlabeled.
Is there an easy way to add a set of labels to the X-axis of the default charts within RTC?
There is no way to cause the charts to have X-axis labels in the small representation in the viewlets. You can, however, click the title of the viewlet to drill in the full version of the chart which includes X-axis labels. You can also "maximize" the viewlet using the button on the viewlet toolbar (top right) to see the full chart without leaving the dashboard.
I have a scenario where in I am using fusion chart which has a multiple line chart in one fusion chart. I want to create a clickable line chart where in clicking on label that particular attribute will be displayed in graph. So basically each line chart in graph is dynamically displayed with click of button for each line chart. I hope you get my requirement. Any help will be really appreciated.
I hope I have understood your requirement correctly.
As far as I know, FusionCharts v3.2 has something similar to what you require.
From the documentation,
Interactive legends in charts that allow for selective showing/hiding of data series (or slicing, in case of pie charts)
You can see a demo of this at FusionCharts gallery
