Multiple Charts

Customizing StockChart

Above StockChart can be further customized to improve the visualization. Here are some of the customizations:

  1. Prefix $ to values on y axis and in toolTip.
  2. Add axis title in charts.
  3. Reduce the height of Volume chart.
  4. Set initial range of the slider.

Adding prefix to the values is pretty simple. You can do so by setting prefix property inside axisY. And to show $ in toolTip, you need to set yValueFormatString inside dataSeries.

Height of individual charts can be controlled using height property. Height can either be mentioned in pixels (like 300, 500) or in percentage (like “50%”, “70%”).

Initial range of the slider can be set by using minimum and maximum properties inside slider.

Below is how the StockChart looks with the above properties set.
