I would like to be able to rotate the chart labels (ie the labels on bar chart bars)
when i have tool many bars in my barchart the labels get jumbled

series: [
showLabels: true,
labels: {textRotationAngle: 90},
…

has no effect

According to the API doc the property name is ‘angle’. Just replace textRotatioAngle with angle and it should work for you.
Here’s how I use it in one of my charts:

     seriesGroups: [{
         type: 'column',
         valueAxis: {
             title: {text: 'Price'}
         },
         series: [{
             dataField: 'Purchase',
             labels: {visible: true, angle: 90}
         }, {
             dataField: 'Sale',
             labels: {visible: true, angle: 90}
         }]
