<%// ChangeColorPalette:%>

<%
// By default, a Tile chart's colors are determined by the ColorScheme
// of the GraphStyle that is in effect for the chart. You can use the
// TileChartModel as follows to change a chart's colors:
//  - Call setColorPaletteType() to set a palette type for the colors
//  - Call getDataElementStyles() and use the returned object to specify colors
//
// This example sets a COLOR_PALETTE_COLOR_SPECTRUM palette type, which
// uses a ColorPosition object to set the colors and their inflection points
// along the color spectrum.
