Remove line shadow?

[tpham]

Is there a way to tone down or remove the shadow of a Line gallery in a chart? In my case, when my data set is dense, the jagged lines may become hard to distingush them apart with their shadows shown and overlapping. Thanks for any pointer.

Coffeescript code looks something like below:

              @chart = new cfx.Chart()
              @chart.getAnimations().getLoad().setEnabled(true)       
              @chart.create("chart_div_#{uid}")
              
              @chart.getData().setSeries(resp.chartData.numOfSeries)
              @chart.getData().setPoints(resp.chartData.numOfPoints)
              for series in [0...resp.chartData.numOfSeries]
                s = @chart.getSeries().getItem(series)
                if series is resp.chartData.numOfSeries-1
                  s.setGallery(cfx.Gallery.Bar)
                  s.sendToBack()
                else
                  s.setGallery(cfx.Gallery.Lines)
              @chart.recalculateScale()
              @chart.setDataSource(resp.chartData.eventData)
