Radial Gauge Animation Bad Values

[mreschke]

Downloaded the full jChartFX package a week ago (not licensed v7.2.5289), built a very simple gauge with animation enabled, works mostly.  Notice in my script the needle value should be right at 82.  Every time I refresh the page the needle varies a bit.  It seems to just pick a random value around 82.  If I hover over the needle it may be 79.0 one time, 80.95 the next, then 81.1...what the heck?

 

I noticed, if I turn off animations, this doesn't happen, needle is exactly at 82 every time.  I notice on slower devices like a phone (android), the need stops even lower, so around 60 - 70.  

 

So animation bug?  Tested in Firefox and Chrome.  Phone is android with chrome.  All three are bad values when animation enabled.

/**

 * Create a jChartFX radial gauge chart from a widget

 * @param  {object} widget

 * @return {void}

 */

function radialGauge(widget)

{

	// Chart Values

	var min = 65;

	var max = 100;

	var value = 82;

	var limit1 = 74;

	var limit2 = 82;

	var name = 'Test';


	// New jChartFX Object

	var chart = new cfx.gauge.RadialGauge();

	chart.setMainValue(value);


	// Titles

	var title = new cfx.gauge.Title();

	chart.getTitles().add(title);

	title = chart.getTitles().getItem(0);

	title.setText(name);


	// Scale

	var scale = chart.getMainScale();


	// Sections 1st

	var section = new cfx.gauge.ScaleSection();

	section.setFrom(min);

	section.setTo(limit1);

	scale.getSections().add(section);


	// Sections 2nd

	section = new cfx.gauge.ScaleSection();

	section.setFrom(limit1);

	section.setTo(limit2);

	scale.getSections().add(section);


	// Sections 3rd

	section = new cfx.gauge.ScaleSection();

	section.setFrom(limit2);

	section.setTo(max);

	scale.getSections().add(section);


	scale.setMin(min);

	scale.setMax(max);


	// Animations

	chart.getAnimations().getLoad().setEnabled(true);


	// Display Chart

	chart.create('myChartDiv');

};

We are testing a new build and it should be made available shortly.
