Class goog.ui.ServerChart

Will construct a chart using Google's chartserver.

Instance Method Summary
	`addDataSet(?Array data, string color, string= opt_legendText)` Adds a data set. NOTE: The color string should NOT have a '#' at the beginning of it.
	`addMultiAxis(?goog.ui.ServerChart.MultiAxisType axisType) ⇒ number` Adds a multi-axis to the chart, and sets its type. Multiple axes of the same type can be added.
	`arrayMax_(?Array ary) ⇒ number` Finds the maximum value in an array and returns it. Needed because Math.max does not handle sparse arrays the way we want.
	`arrayMin_(?Array ary) ⇒ number` Finds the minimum value in an array and returns it. Needed because Math.min does not handle sparse arrays the way we want.
	`clearDataSets()` Clears the data sets from the graph. All data, including the colors and legend text, is cleared.
	`computeDataStringForEncoding_(?goog.ui.ServerChart.EncodingType encoding) ⇒ boolean` Computes the data string using the data in this.dataSets_ and the encoding specified by the encoding parameter, which must not be AUTOMATIC, and sets the object's URI accordingly.
	`computeDataString_()` Computes the data string using the data in this.dataSets_ and sets the object's URI accordingly. If the URI's length equals or exceeds the limit, goog.ui.ServerChart.UriTooLongEvent is dispatched on the goog.ui.ServerChart object.
	`computeMultiAxisDataString_(?Object data, string indexSeparator, string elementSeparator, string axisSeparator) ⇒ string` Computes a multi-axis data string from the given data and separators. The general data format for each index/element in the array will be "", with axisSeparator used between multiple elements.
	`createDom()` Creates the DOM node (image) needed for the Chart
	`decorateInternal(?Element img)` Decorate an image already in the DOM. Expects the following structure: - img
	`disposeInternal()` Disposes of the component. Calls {@code exitDocument}, which is expected to remove event handlers and clean up the component. Propagates the call to the component's children, if any. Removes the component's DOM from the document unless it was decorated.
	`getBackgroundFill() ⇒ ?Array` Returns the background fill.
	`getChartServerValues_(?Array values, number minValue, number maxValue, ?goog.ui.ServerChart.EncodingType encoding) ⇒ string` Creates the chd string for chartserver.
	`getConvertedValue_(?number value, number minValue, number maxValue, ?goog.ui.ServerChart.EncodingType encoding) ⇒ string` Converts a single number to an encoded data value suitable for ChartServer. The TEXT encoding is the number in decimal; the SIMPLE encoding is a single character, and the EXTENDED encoding is two characters. See http://code.google.com/apis/chart/docs/data_formats.html for the detailed specification of these encoding formats.
	`getData(number= opt_setNumber) ⇒ ?Array` Returns the given data set or all of them in a two-dimensional array if the set number is not given.
	`getEncodingType() ⇒ ?goog.ui.ServerChart.EncodingType` Gets the encoding type.

	`setAutomaticBarWidth(number= opt_spaceBars, number= opt_spaceGroups)` Specifies that the bar width in a bar chart should be calculated automatically given the space available in the chart, while optionally setting the spaces between the bars. NOTE: If the space between groups is specified but the space between bars is left undefined, the space between groups will be interpreted as the space between bars because this is the behavior exposed in the external developers guide.
	`setBackgroundFill(?Array fill)` Sets the background fill.
	`setBarSpaceWidths(number barWidth, number= opt_spaceBars, number= opt_spaceGroups)` Sets the widths of the bars and the spaces between the bars in a bar chart.
