[jqplot-users]dynamically update data and not loose zoom

[Olga]

Hi!

Jqplot has an example where the data is dynamically updated (dynamicplot.html).

I think it would be really nice-to-have jqplot method like appendData(<array of data to be appended>). It would be useful for real-time dataseries.

It's not difficult to implement but there's a zooming problem. For example if we apply zoom in dynamicplot example, each time data is updated the chart is replotted and zoomed area is no longer zoomed.

It is also possible to implement but requires more deep knowledge of jqplot api, datastructures etc etc.

I'd like to ask if there is some work in this direction (give the possibility to easily update data and not to loose the zoom).

If there are no predictability for these features I will implement them. In this case i'd like to ask if I can submit the patches after the work done.

Sincerely,

--Olga

I don't have any plans in the near future to implement.  I would welcome a patch if you get this working.  Thanks!

Made a work around to prevent resetting of the zoomed area. By checking the isZoomed variable  

if(Myplot.plugins.cursor._zoom.isZoomed == true) 

       Myplot.replot();

else

       Myplot.replot({resetAxes:true});
