## Detailed Description

Charting diagram interfaces.

## Typedef Documentation

## ◆ ChartDataPoint

typedef sequence<ChartDataValue> ChartDataPoint
| published

Deprecated

## Enumeration Type Documentation

## ◆ ChartAxisArrangeOrderType

enum ChartAxisArrangeOrderType
| published

Values specify the arrangement of the axes descriptions.

Enumerator
AUTO | The descriptions are arranged automatically.
    <p>If there is enough space to put them side by side, this
    arrangement is preferred. If the descriptions would overlap
    when arranged side by side, they are staggered.</p>
SIDE_BY_SIDE | The descriptions are arranged side by side.
STAGGER_EVEN | The descriptions are alternately put on two lines with the even values out of the normal line.
STAGGER_ODD | The descriptions are alternately put on two lines with the odd values out of the normal line.

## ◆ ChartAxisLabelPosition

enum ChartAxisLabelPosition
| published

Specifies the position of the axis labels with respect to the axis on the scale of the crossing axis.

Enumerator
NEAR_AXIS | The labels are placed adjacent to the axis. When the axis itself is placed at the minimum or maximum of the scale ( that is when the property CrossoverPosition equals ChartAxisPosition_MINIMUM or ChartAxisPosition_MAXIMUM) the labels are placed outside the coordinate system. Otherwise the labels are placed adjacent to the axis on that side that belongs to the lower values on the crossing axis. E.g. when the ChartAxisLabelPosition is set to NEAR_AXIS for an y axis the labels are placed adjacent to the y axis on that side that belongs to the lower x values.
NEAR_AXIS_OTHER_SIDE | The labels are placed adjacent to the axis on the opposite side as for NEAR_AXIS.
OUTSIDE_START | The labels are placed outside the coordinate region on that side where the crossing axis has its minimum value. E.g. when this is set for an y axis the labels are placed outside the diagram on that side where to the x axis has its minimum value.
OUTSIDE_END | The labels are placed outside the coordinate region on that side where the crossing axis has its maximum value. E.g. when this is set for an y axis the labels are placed outside the diagram on that side where to the x axis has its maximum value.

## ◆ ChartAxisMarkPosition

enum ChartAxisMarkPosition
| published

Specifies the position of the axis interval marks.

Enumerator
AT_LABELS | The interval marks are drawn besides the axis labels.
AT_AXIS | The interval marks are drawn at the axis line. This makes a difference to "AT_LABELS" only when the labels are not placed near the axis ( See also ChartAxisLabelPosition).
AT_LABELS_AND_AXIS | Interval marks are drawn at the axis line and also besides the axis labels. This makes a difference to "AT_LABELS" only when the labels are not placed near the axis ( See also ChartAxisLabelPosition).

## ◆ ChartAxisPosition

enum ChartAxisPosition
| published

Specifies the position of the axis on the scale of the crossing axis.

When the property is set at a x-axis it indicates a position on the scale of the primary y-axis. When the property is set at a y-axis it indicates a position on the scale of the primary x-axis.

Enumerator
ZERO | Cross the other axes at zero. If zero is not contained in the current scale the value is used which is nearest to zero.
START | Cross the other axes at their minimum scale value.
END | Cross the other axes at their maximum scale value.
VALUE | Cross the other axes at the value specified in the property CrossoverValue.

## ◆ ChartDataChangeType

enum ChartDataChangeType
| published

specifies the type of change that was applied to the data.

Enumerator
ALL | Major changes were applied to the data.
DATA_RANGE | The range of columns and rows, given in the ChartDataChangeEvent, has changed.
COLUMN_INSERTED | The column given in the ChartDataChangeEvent, was inserted.
ROW_INSERTED | The row given in the ChartDataChangeEvent, was inserted.
COLUMN_DELETED | The column given in the ChartDataChangeEvent, was deleted.
ROW_DELETED | The row given in the ChartDataChangeEvent, was deleted.

## ◆ ChartDataRowSource

enum ChartDataRowSource
| published

specifies if the data rows (aka data series) displayed in the chart, take their values from the row or the column in the underlying data source (ChartDataArray).

Enumerator
ROWS | values displayed as data rows are taken from the rows of the data source.
COLUMNS | values displayed as data rows are taken from the columns of the data source.

## ◆ ChartErrorCategory

enum ChartErrorCategory
| published

specifies the category of error indicators.

Enumerator
NONE | error indicators are not displayed. displays no regression curve. no chart legend is displayed. displays no error indicators.
    <p>To disable the legend you should set the property
    ChartDocument::HasLegend to `FALSE` instead
    of setting this value.</p>
VARIANCE | displays error indicators for the variance of the data row.
STANDARD_DEVIATION | displays error indicators for the standard deviation (square root of variance) of the data row.
PERCENT | The length of the error indicators is calculated for each data point by taking the percentage given as ChartStatistics::PercentageError of its value. See also ChartStatistics
ERROR_MARGIN | The length of the error indicators for all data points is calculated by taking the percentage given as ChartStatistics::ErrorMargin of the largest data point value. See also ChartStatistics
CONSTANT_VALUE | displays the same lower and upper error indicators for all data points. The values for these are given as absolute numbers in ChartStatistics::ConstantErrorLow and ChartStatistics::ConstantErrorHigh See also ChartStatistics

## ◆ ChartErrorIndicatorType

enum ChartErrorIndicatorType
| published

specifies how the error is indicated.

Enumerator
NONE | error indicators are not displayed. displays no regression curve. no chart legend is displayed. displays no error indicators.
    <p>To disable the legend you should set the property
    ChartDocument::HasLegend to `FALSE` instead
    of setting this value.</p>
TOP_AND_BOTTOM | displays both the upper and lower values.
UPPER | displays only the upper value.
LOWER | displays only the lower value.

## ◆ ChartLegendExpansion

enum ChartLegendExpansion

Specifies sizing aspects of the legend.

Enumerator
WIDE | The legend entries are arranged in a single row if possible. If not enough space is available further rows are added.
    <p>This is usually used for legends that are displayed at the
    top or bottom of the page.</p>
HIGH | The legend entries are stacked in a single column if possible. If not enough space is available further columns are added.
    <p>This is usually used for legends that are displayed on the
    left or right hand side of the page.</p>
BALANCED | The legend entries are arranged in a way that the aspect ratio of the resulting legend is as near to 1 as possible.
CUSTOM | The size of the legend is given explicitly.

## ◆ ChartLegendPosition

enum ChartLegendPosition
| published

specifies one of the default positions of the legend in relation to the diagram.

Enumerator
NONE | error indicators are not displayed. displays no regression curve. no chart legend is displayed. displays no error indicators.
    <p>To disable the legend you should set the property
    ChartDocument::HasLegend to `FALSE` instead
    of setting this value.</p>
LEFT | displays the chart legend on the left side of the diagram.
    <p>The second entry in the legend is placed below the first
    one.</p>
