Properties

#comparable

Type booleanDefault false

Specifies whether this graph will be compared if some data set is selected for comparing.

#compareField

Type string

Specifies a field to be used to generate comparing graph. Note, this field is not the one used in your dataProvider, but toField from FieldMapping object.

#compareFromStart

Type booleanDefault false

If you set it to true, when data sets are compared, the graphs will use first value as a base value instead of using the first value of selected period.

#compareGraph

Type AmGraph

You can use this property to set config of compared graphs. This allows you to set any of AmGraph properties on compared graphs instead of using old-style properties like compareGraphBulletBorderThickness. For example: stockGraph.compareGraph = {“bulletBorderThickness”:2, “lineAlpha”:0.4}.

#compareGraphBalloonColor

Type color

Balloon color of comparing graph.

#compareGraphBalloonFunction

If you set some function, the graph will call it and pass GraphDataItem and AmGraph object to it. This function should return a string which will be displayed in a balloon. This will be used for graphs from compared data sets only. Use balloonFunction for main data set's graphs.

#compareGraphBalloonText

Type string

Balloon text of comparing graph.

#compareGraphBullet

Type string

Bullet of comparing graph. Possible values are: round, square, diamond, triangleUp, triangleDown, triangleLeft, triangleRight, bubble

#compareGraphBulletBorderAlpha

Type number

Opacity of bullet border of comparing graph.

#compareGraphBulletBorderColor

Type color

Color of bullet border of comparing graph.

#compareGraphBulletBorderThickness

Type number

Thickness of bullet border of comparing graph.

#compareGraphBulletColor

Type color

Color of compared graphs' bullets.

#compareGraphBulletSize

Type number

Bullet size of comparing graph.

#compareGraphCornerRadiusTop

Type number

Corner radius of comparing graph (if type is "column").

#compareGraphDashLength

Type number

Dash length of compare graph.

#compareGraphFillAlphas

Type number

Fill alpha of comparing graph.

#compareGraphFillColors

Type color

Fill color of comparing graph.

#compareGraphLineAlpha

Type number

Opacity of comparing graph line.

#compareGraphLineColor

Type color

Color of compare graph (by default data set color is used)

#compareGraphLineThickness

Type number

Thickness of compare graph.

#compareGraphType

Type stringDefault line

Type of comparing graph. Possible values are: "line", "column", "step", "smoothedLine."

#compareGraphVisibleInLegend

Type booleanDefault true

Specifies if compare graph is visible in legend.

#periodValue

Type stringDefault Close

When data is grouped to periods, the graph must know which period value should be used. Possible values are: "Open", "Low", "High", "Close", "Average" and "Sum".

#recalculateValue

Type number/string

Possible values are Open, Close, High, Low, Average and Sum. There is no default value set – graph uses it’s periodValue when calculating changes. For example, the graph’s periodValue is Close. This means that when data is grouped to longer periods (months for example) when recalculating, the graph will use Close value of the first period of the selection as base value and will compare each months Close value to it. If you set recalculateValue to Open, the first value of a month will be used as base value.

#showEventsOnComparedGraphs

Type booleanDefault false

Specifies if events of compared graphs should be shown.

#useDataSetColors

Type booleanDefault true

Specifies whether data set color should be used as this graph's lineColor. By default all graphs from the same data set will have a color from its relative DataSet (either auto-assigned by chart or set by color parameter). The graph's color properties will be ignored.

To disable this behavior, set "useDataSetColors" to false. This way the chart will use graph's own color settings, such as "lineColor" or auto-assign the color if those are not set.

111 inherited items

#accessibleLabel

Type stringDefault [[title]] [[category]] [[value]]Inherited from AmGraph

Text which screen readers will read if user rolls-over the bullet/column or sets focus using tab key (this is possible only if tabIndex property of AmGraph is set to some number). Text is added as aria-label tag. Note - not all screen readers and browsers support this.

#alphaField

Type stringInherited from AmGraph

Name of the alpha field in your dataProvider.

#animationPlayed

Type booleanDefault falseInherited from AmGraph

If you set this to true before chart is drawn, the animation of this graph won't be played.

#balloonColor

Type colorInherited from AmGraph

Value balloon color. Will use graph or data item color if not set.

#balloonFunction

Inherited from AmGraph

If you set some function, the graph will call it and pass GraphDataItem and AmGraph objects to it. This function should return a string which will be displayed in a balloon.

#balloonText

Type stringDefault [[value]]Inherited from AmGraph

#bulletAxis

Type ValueAxisInherited from AmGraph

bulletAxis value is used when you are building error chart. Error chart is a regular serial or XY chart with bullet type set to "xError" or "yError". The graph should know which axis should be used to determine the size of this bullet - that's when bulletAxis should be set. Besides that, you should also set graph.errorField. You can also use other bullet types with this feature too. For example, if you set bulletAxis for XY chart, the size of a bullet will change as you zoom the chart.

#bulletBorderAlpha

Note, cornerRadiusTop will be applied for all corners of the column, JavaScript charts do not have a possibility to set separate corner radius for top and bottom. As we want all the property names to be the same both on JS and Flex, we didn't change this too.

#cursorBulletAlpha

Type numberDefault 1Inherited from AmGraph

If bulletsEnabled of ChartCurosor is true, a bullet on each graph follows the cursor. You can set opacity of each graphs bullet. In case you want to disable these bullets for a certain graph, set opacity to 0.

#fillToGraph

Type AmGraphInherited from AmGraph

You can set another graph here and if fillAlpha is >0, the area from this graph to fillToGraph will be filled (instead of filling the area to the X axis). This feature is not supported by smoothedLine graphs and Radar chart.

It is useful if you have really lots of data points. Based on this property the graph will omit some of the lines (if the distance between points is less that minDistance, in pixels). This will not affect the bullets or indicator in anyway, so the user will not see any difference (unless you set minValue to a bigger value, let say 5), but will increase performance as less lines will be drawn. By setting value to a bigger number you can also make your lines look less jagged.

#negativeBase

For example: {"url":"../amcharts/patterns/black/pattern1.png", "width":4, "height":4}. If you want to have individual patterns for each column, define patterns in data provider and set graph.patternField property. Check amcharts/patterns folder for some patterns. You can create your own patterns and use them. Note, x, y, randomX and randomY properties won't work with IE8 and older. 3D bar/Pie charts won't work properly with patterns.

#precision

Type numberInherited from AmGraph

Precision of values. Will use chart's precision if not set any.

#proCandlesticks

Type booleanDefault falseInherited from AmGraph

If this is set to true, candlesticks will be colored in a different manner - if current close is less than current open, the candlestick will be empty, otherwise - filled with color. If previous close is less than current close, the candlestick will use positive color, otherwise - negative color.

#showAllValueLabels

Type booleanDefault falseInherited from AmGraph

If graph's type is column and labelText is set, graph hides labels which do not fit into the column's space or go outside plot area. If you don't want these labels to be hidden, set this to true.

#showBalloon

Type booleanDefault trueInherited from AmGraph

Specifies whether the value balloon of this graph is shown when mouse is over data item or chart's indicator is over some series.

#showBalloonAt

Type stringDefault closeInherited from AmGraph

Specifies graphs value at which cursor is showed. This is only important for candlestick and ohlc charts, also if column chart has "open" value. Possible values are: "open", "close", "high", "low". "top" and "bottom" values will glue the balloon to top/bottom of the plot area.

#showBulletsAt

Works with candlestick graph type, you can set it to open, close, high, low. If you set it to high, the events will be shown at the tip of the high line.

#showHandOnHover

Type booleanDefault falseInherited from AmGraph

If you want mouse pointer to change to hand when hovering the graph, set this property to true.

#showOnAxis

Type booleanDefault falseInherited from AmGraph

It can only be used together with topRadius (when columns look like cylinders). If you set it to true, the cylinder will be lowered down so that the center of it's bottom circle would be right on category axis.

#stackable

Type booleanDefault trueInherited from AmGraph

If the value axis of this graph has stack types like "regular" or "100%" You can exclude this graph from stacking.

#stepDirection

Type stringDefault rightInherited from AmGraph

Step graph only. Specifies to which direction step should be drawn.

#switchable

Type booleanDefault trueInherited from AmGraph

If you set it to false, the graph will not be hidden when user clicks on legend entry.

#tabIndex

Type numberInherited from AmGraph

In case you set it to some number, the chart will set focus on bullet/column (starting from first) when user clicks tab key. When a focus is set, screen readers like NVDA Screen reader will read label which is set using accessibleLabel property of AmGraph. Note, not all browsers and readers support this.

#title

Type stringInherited from AmGraph

Graph title.

#topRadius

Type numberInherited from AmGraph

If you set this to 1, columns will become cylinders (must set depth3D and angle properties of a chart to >0 values in order this to be visible). you can make columns look like cones (set topRadius to 0) or even like some glasses (set to bigger than 1). We strongly recommend setting grid opacity to 0 in order this to look good.

#type

Type stringDefault lineInherited from AmGraph

Type of the graph. Possible values are: "line", "column", "step", "smoothedLine", "candlestick", "ohlc". XY and Radar charts can only display "line" type graphs.
