ChartData<T extends IDataSet<Entry>> class
Methods
-
addDataSet(T d)
→ void
-
Adds a DataSet dynamically.
-
addEntry(Entry e, int dataSetIndex)
→ void
-
Adds an Entry to the DataSet at the specified index.
Entries are added to the end of the list.
-
addEntryByIndex(int index, Entry e, int dataSetIndex)
→ void
-
-
calcMinMax1()
→ void
-
Calc minimum and maximum values (both x and y) over all DataSets.
-
calcMinMax2(Entry e, AxisDependency axis)
→ void
-
Adjusts the current minimum and maximum values based on the provided Entry object.
-
calcMinMax3(T d)
→ void
-
Adjusts the minimum and maximum values based on the given DataSet.
-
calcMinMaxY(double fromX, double toX)
→ void
-
Calc minimum and maximum y-values over all DataSets.
Tell DataSets to recalculate their min and max y-values, this is only needed for autoScaleMinMax.
-
clearValues()
→ void
-
Clears this data object from all DataSets and removes all Entries. Don't
forget to invalidate the chart after this.
-
contains(T dataSet)
→ bool
-
Checks if this data object contains the specified DataSet. Returns true
if so, false if not.
-
getColors()
→ List<Color?>?
-
Returns all colors used across all DataSet objects this object
represents.
-
getDataSetByIndex(int index)
→ T?
-
-
getDataSetByLabel(String label, bool ignorecase)
→ T?
-
Returns the DataSet object with the given label. Search can be case
sensitive or not. IMPORTANT: This method does calculations at runtime.
Use with care in performance critical situations.
-
getDataSetCount()
→ int
-
returns the number of LineDataSets this object contains
-
getDataSetForEntry(Entry e)
→ T?
-
Returns the DataSet that contains the provided Entry, or null, if no
DataSet contains this Entry.
-
getDataSetIndexByLabel(List<T>? dataSets, String label, bool ignorecase)
→ int
-
Retrieve the index of a DataSet with a specific label from the ChartData.
Search can be case sensitive or not. IMPORTANT: This method does
calculations at runtime, do not over-use in performance critical
situations.
-
getDataSetLabels()
→ List<String?>
-
Returns the labels of all DataSets as a string array.
-
getEntryCount()
→ int
-
Returns the total entry count across all DataSet objects this data object contains.
-
getEntryForHighlight(Highlight? highlight)
→ Entry?
-
Get the Entry for a corresponding highlight object
-
getFirstLeft(List<T> sets)
→ T?
-
Returns the first DataSet from the datasets-array that has it's dependency on the left axis.
Returns null if no DataSet with left dependency could be found.
-
getFirstRight(List<T> sets)
→ T?
-
Returns the first DataSet from the datasets-array that has it's dependency on the right axis.
Returns null if no DataSet with right dependency could be found.
-
getIndexOfDataSet(T dataSet)
→ int
-
Returns the index of the provided DataSet in the DataSet array of this data object, or -1 if it does not exist.
-
getMaxEntryCountSet()
→ T?
-
Returns the DataSet object with the maximum number of entries or null if there are no DataSets.
-
getYMax1()
→ double
-
Returns the greatest y-value the data object contains.
-
getYMax2(AxisDependency axis)
→ double?
-
Returns the maximum y-value for the specified axis.
-
getYMin1()
→ double
-
Returns the smallest y-value the data object contains.
-
getYMin2(AxisDependency axis)
→ double?
-
Returns the minimum y-value for the specified axis.
-
isHighlightEnabled()
→ bool
-
Returns true if highlighting of all underlying values is enabled, false
if not.
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyDataChanged()
→ void
-
Call this method to let the ChartData know that the underlying data has
changed. Calling this performs all necessary recalculations needed when
the contained data has changed.
-
removeDataSet1(T d)
→ bool
-
Removes the given DataSet from this data object. Also recalculates all
minimum and maximum values. Returns true if a DataSet was removed, false
if no DataSet could be removed.
-
removeDataSet2(int index)
→ bool
-
Removes the DataSet at the given index in the DataSet array from the data
object. Also recalculates all minimum and maximum values. Returns true if
a DataSet was removed, false if no DataSet could be removed.
-
removeEntry1(Entry e, int dataSetIndex)
→ bool
-
Removes the given Entry object from the DataSet at the specified index.
-
removeEntry2(double xValue, int dataSetIndex)
→ bool
-
Removes the Entry object closest to the given DataSet at the
specified index. Returns true if an Entry was removed, false if no Entry
was found that meets the specified requirements.
-
setDrawValues(bool enabled)
→ void
-
Enables / disables drawing values (value-text) for all DataSets this data
object contains.
-
setHighlightEnabled(bool enabled)
→ void
-
Enables / disables highlighting values for all DataSets this data object
contains. If set to true, this means that values can
be highlighted programmatically or by touch gesture.
-
setValueFormatter(ValueFormatter f)
→ void
-
Sets a custom IValueFormatter for all DataSets this data object contains.
-
setValueTextColor(Color color)
→ void
-
Sets the color of the value-text (color in which the value-labels are
drawn) for all DataSets this data object contains.
-
setValueTextColors(List<Color> colors)
→ void
-
Sets the same list of value-colors for all DataSets this
data object contains.
-
setValueTextSize(double size)
→ void
-
Sets the size (in dp) of the value-text for all DataSets this data object
contains.
-
setValueTypeface(TypeFace tf)
→ void
-
Sets the Typeface for all value-labels for all DataSets this data object
contains.
-
toString()
→ String
-
A string representation of this object.
