I am trying to change the theme option in any of the chart but it seems that it didn't work. I had folowwed instructions as what you mentioned to load the amCharts theme in the app.js but it didn';t work either.

In my app.js file,

/**

  */

define([
'angular',
'mango-3.3/maMaterialDashboards',
'mango-3.3/maAppComponents',
'require',
'./services/Page',
'./directives/pageView/pageView',
'./directives/liveEditor/livePreview',
'moment-timezone',
'angular-ui-router',
'oclazyload',
'angular-loading-bar',
'./views/docs/docs-setup',
'amcharts/themes/dark'
], function(angular, maMaterialDashboards, maAppComponents, require, Page, pageView, livePreview, moment) {
'use strict';....

I added the that line which you mentioned at the end. However, there is no effect on the chart colour.
Please see the chart option as below:

ma-serial-chart style="height: 300px; width: 100%" series-1-values="point1Values" series-1-point="point1" legend="true" balloon="true" export="true"
options="{theme: 'dark', chartScrollbar:{'enabled': true, 'scrollbarHeight': 5}, export: {'position': 'bottom-right'}, valueAxes: [{'id': 'ValueAxis-1','color': '#FFFFFF'}]}"

</ma-serial-chart>

Can you please see what other settings need to be done in order for the theme to work in the chart? Thanks alot.
