background and legend is not affected by theme

[kfirufk]

Hi.

I'm using amcharts 3.15.2, with amcharts-angular 1.0.4 and angularjs 1.5.7 with angular material 1.0.9.

when I set a theme or even when I don't set a theme... which defaults to light theme, the background color and legend text color is not set. i checked on google chrome console to see if there is a rule to set the background color and something else overrides it, but nothing!

for now I worked around the issue by connect each graph to the drawn event:

ChatOptionsObj = {
...
listeners: [{
"event": "drawn",
"method": caller.handleGraphsRenderEvent
}],
...
}

and setting the following functions:

     caller.handleGraphsRenderEvent = function (event) {
            caller.setChartsBgColor(event.chart.backgroundColor);
            caller.setChartsLegendColor(event.chart.color);
        }
       caller.setChartsBgColor = function(color) {
            $('div.amchart').css('background-color',color);
        }
        caller.setChartsLegendColor = function (color) {
            $('div.amChartsLegend').find('text').attr('fill',color);
        }

as you can see in the drawn event, i fetch the background color and color properties which are set properly (the event.chart.legend.color is not set properly).

thanks!
