Bug Fixes

  1. In case of area chart, enclosed region was not being filled properly when dataSeries is attached to secondary x-axis.
  2. In few cases, axis ticks were getting skipped along with axis labels instead of just skipping labels.
  3. Chart Bounds was not getting updated after chart-resize.
  4. Error was being thrown whenever chart had only one datapoint with label & labelWrap set to true.
