Do you guys plan on adding support for the HTML5 canvas any time soon? We use your VCL and ActiveX charts in our PC software, but as we migrate towards web apps, we are wondering if we should roll our own charts, convert to a charting component like FLOT, or wait for an HTML5 canvas version of TeeChart.

Thanks for any info.

Hi TMECHAM,

We spoke about supporting HTML code for all text strings that can be used in TeeChart. However, we have no plans for a HTML 5 canvas for now. Anyway, I'll add your request to the wish-list to be considered for inclusion in future releases.

Add me to the list wishing for this support - HTML 5 support is huge because of the iPhone. What we really want is one package that can deliver the exact same chart to our customers in both native .exe (VCL) and web versions - I would buy that version today and I think that is the competitive advantage that your company needs to leverage to really be successful.

We appreciate your comments and suggestions. We'll take them into account.

Hello everyone,

As an update, we have a first version of an HTML 5 canvas for TeeChart 2010 VCL. I'll send it to you by e-mail so that you can test it at your end. You can find TeeChart 2010 VCL fully functional evaluation versions at http://www.steema.com/evaluation/vcl.

Thanks in advance.

This is great news! Any idea when support will be in the ActiveX version?

Thanks!

Hi tmecham,

I'm afraid it's too early to be able to provide a date. The HTML 5 canvas hasn't been finished yet.

Please let me know when something is available. We are currently converting our TeeChart graph to FLOT and there is just too much missing from FLOT for this to be a long term solution for us.

Thanks!

Hi tmecham,

In that case I recommend you to be aware at this forums board, our RSS news feed, twitter or facebook accounts for new release announcements and what's implemented on them.

Thanks in advance.

Hello,

We've just put a preview of Steema's 2012 prototype HTML5 TeeChart here: http://www.steema.com/entry/91/TeeChart ... rt_Preview. The protoype differs from existing TeeChart HTML5 Chart output in running the chart engine in native javascript at the client before generating the html5 canvas instructions (rather than sending html5 plot primitives directly to the canvas as in the currently shipping version). This offers advantages of providing greater chart interactivity at the client via navigation (zoom/scroll) and animation techniques.

We're interested in customer feedback as we move this development forward, ie. what kind of chart types are priority to our customers; any wishes for inclusions and other comments would be welcome.

With thanks!
Regards,
Marc Meumann

We also use TCharts and are looking at migrating our systems onto a web platform and although I was excited by HTML5 support, our applications use TeeTree for workflow diagrams. I am wondering if there are any plans to migrate TeeTree to HTML5 as well or if we are better off with another component.

Hello,

I'm afraid we don't have plans to migrate TeeTree to HTML5.
However, the menu on the left in TeeChart HTML5 Reference Demo draws a tree.
Regarding shapes and diagrams, you can always draw them manually with TeeChart HTML5 using custom drawing functions, as shown in the Custom Painting demo.
