 Client-side ChartDir |

Are there any thoughts about creating a client-side version (maybe a simplified version to
start with) or relative of ChartDir that would be controlled via JavaScript and that could
generate chart images locally within a web page (ie and not as a separately generated and
downloaded image)? Something like a competitor to eg RGraph (www.rgraph.net)?
This would be great for creating live charts in a web page that could then be updated
automatically by very small downloads of text data.
(I can't see that this is an existing feature of ChartDir, but maybe I've missed it?) |

Hi johnd,
Thank you very much for your valuable suggestion.
Whereas there are many client side support in ChartDirector, they are intended for standalone programs or clients (like for MFC/QT Windows application, .NET Windows Forms, Java SWING, VB6, ...). If you need the client to run inside a browser, currently the only supported technology is Java Applets (with ChartDirector for JSP/Java).
We have been thinking about using Javascript for a while, but ChartDirector currently is too feature rich and too large for Javascript. We probably has to break it down into many smaller pieces, so that the web page only loads the pieces it needs. We may also have to leave out some computationally intensive charts like contour and surface charts (Javascript may be too slow computationally intensive tasks).

Peter, have you had any further thoughts on client-side Javascript? So many applications
are heading in the direction of being implemented within the browser and we need to follow
this trend. It would be good to keep using ChartDir here, even if it was a cut-down version,
but right now it's obviously not an option. |

Hi John,
We are seriously considering this option (that the charts are generated by Javascript with no server side code), and we do have not a confirmed scheduled yet.
