Animation in meterGauge chart

[roycebautista]

I would like to request an enhancement to the existing meterGauge chart.

The desired enhancement is a needle animation effect similar to this: http://bl.ocks.org/msqr/3202712

It doesn't have to be exactly like that, just a simple animation to give the experience of a moving needle as the values increases or decreases.

Thanks.

Good idea ! Planned into 1.0.10.

Cool idea! Could use something like this as well. Will D3.js become a dependency for jqPlot for this feature?

[roycebautista]

I don't think so. The bar chart already has animation without dependency on D3.js.

D3 is a svg building library. JQplot builds HTML5 canvas.

This is two different way to builds charts on the web. If we would like to integrate D3 features, we need to rewrite a new build system using SVG.

Since this is an old post.. Has this already been implemented ? how can we animate the needle in the meter gauge. Dint find any reference about it online..

Not yet implemented because of complexity to rebuild chart on each animation. Canvas animations needs to rebuild a location on the canvas chart. Doing that means that cleared region need to be rebuilt. My try to animate it causes performances issues.

I study an alternative to this point.
