Q & A:

A lot of questions were asked in the webinar. We were able to answer some of the them. So I will be trying to collate all the questions asked during the webinar and put them here in this blog post. So here are the questions from the webinar and their answers:

Q: Can we add series items dynamically and show legend with this dynamic name?
A: Yes this is supported. You can use data source for dynamically creating a chart based on the data in the DB.

Q: Can these charts be exported?
A: Yes you can. Take a look at the following example: http://www.telerik.com/community/code-library/aspnet-ajax/html-chart/exporting-radhtmlchart-to-png-and-pdf.aspx

Q: Is there a version available for MVC?
A: Yes we do. Please look at http://www.kendoui.com/server-wrappers/mvc.aspx

Q: is there a option for additional x-axis?
A: No. We support additional Y axis

Q: How many Additional Y Axis we can add?
A: Unlimited.

Q: Do we need to install SVG viewer?
A: No. All browsers support SVG. So no need to install anything. Older browsers support VML. So we fallback to VML when we see that its an older browser.

Q: We already have Telerik controls, do we have chart control there?
A: Yes you have. RadHtmlChart is supported from Q2 2012 onwards.

Q: Can we zoom or pan this chart or lines?
A: RadHtmlChart at the moment does not support the Zoom or Pan feature.

Q: Are these printer freindly?
A: While the charts can be printed, we have a reporting suite more suitable for printing requirements that supports charts, barcodes etc. http://www.telerik.com/products/reporting.aspx

Q: Does this supports mobile development also?
A: We have another suite more suitable for mobile development called Kendo DataViz. http://www.kendoui.com/dataviz.aspx

Q: What is the benefit of HTML 5 charts than Visual Studio .net , i mean asp.net chart?
A: ASP.NET charting controls generate the charts on the server side as IMAGE and then send it to the client. Where as RadHtmlChart does client side rendering of the chart. RadHtmlChart outputs SVG which is a HTML5 standard where as ASP.NET chart is still a IMAGE.

Q: Can we create speedometer dials using the html5 instead of dojo tool kit
A: http://demos.kendoui.com/dataviz/radial-gauge/index.html

Q: Chart drill down is also possible?
A: No. Drill down is not supported at the moment. But you can implement this easily by listening to OnSeriesClicked client side event.

Q: Is there an option to update the controls periodically to fetch data from db?
A: You will need to implement this by writing some code. Since RadHtmlChart supports client side binding, you can ping a JSON end point, get the data and bind it to the RadHtmlChart on the client side. You can have a window timer and get the data periodicaly.

Q: What is the difference between HTML 5 Application Cache and regular HTML Browser Cache?
A: App Cache is a feature introduced by HTML 5 spec that is available for developers. Browser Cache is a location where browser caches all data e.g. images, HTML etc.

Q: Are more than 5 colors available in pie chart?
A: With the release of Q2 2013, RadHtmlChart now has 10 built-in colors for the series for each skin.

      • I wanted to know whether the canvas supports or not the radhtml chart or not. It was not in context to the seminar. If I have understood corrrectly your answer the RadHTML Chart will not be displayed in canvas and I have also got it clarified.
