I can't manage to setup the BackgroundChart. No matter what data I put into the float array for the chart values I get an arithmetic exception. It occures in the onSetupChartPath() methode where the chartPointStep is calculated. The mWidth is always 0 so the divide by zero arithmetic exception occures.
