Methods

Append

public void Append(IEnumerable<TX> x, IEnumerable<TY> y0, IEnumerable<TY> y1)

xyyDataSeries.Append(x, y0, y1)

Appends a collection of X, Y0 and Y1 points to the series, automatically triggering a redraw

x: The X-values
y0: The Y0-values
y1: The Y1-values

Append

public void Append(TX x, TY y0, TY y1)

xyyDataSeries.Append(x, y0, y1)

Appends a single X, Y0, Y1 point to the series, automatically triggering a redraw

x: The X-value
y0: The Y0-value
y1: The Y1-value

Append

public override void Append(IEnumerable<TX> x, IEnumerable<TY>[] yValues)

xyyDataSeries.Append(x, yValues)

Appends a list of X, Y points to the series

x: The list of X points
yValues: Lists of Y points (depends on series type)

Append

public override void Append(TX x, TY[] yValues)

xyyDataSeries.Append(x, yValues)

Appends an X, Y point to the series

x: The X Value
yValues: The Y Values (depends on series type)

ClearColumns

protected override void ClearColumns()

xyyDataSeries.ClearColumns()

When overridden in a derived class, clears all columns in the Data Series

Clone

public override IDataSeries<TX, TY> Clone()

result = xyyDataSeries.Clone()

Creates a deep copy of a DataSeries

GetYMaxAt

public override TY GetYMaxAt(int index, TY existingYMax)

result = xyyDataSeries.GetYMaxAt(index, existingYMax)

When overriden in a derived class, gets the Max(existingYMax, currentMax), where currentMax is the maximum at the specified index

index: The index to the underlying dataset
existingYMax: The existing maximum

Returns: The new YMax, which is the Min(existingYMax, currentMax)

GetYMinAt

public override TY GetYMinAt(int index, TY existingYMin)

result = xyyDataSeries.GetYMinAt(index, existingYMin)

When overriden in a derived class, gets the Min(existingYMin, currentMin), where currentMin is the minimum at the specified index

index: The index to the underlying dataset
existingYMin: The existing minimum

Returns: The new YMin, which is the Min(existingYMin, currentMin)

Insert

public void Insert(int index, TX x, TY y0, TY y1)

xyyDataSeries.Insert(index, x, y0, y1)

Inserts an X, Y0, Y1 point at the specified index. Automatically triggers a redraw

index: The index to insert at
x: The X-value
y0: The Y0-value
y1: The Y1-value

InsertRange

public void InsertRange(int startIndex, IEnumerable<TX> x, IEnumerable<TY> y0, IEnumerable<TY> y1)

xyyDataSeries.InsertRange(startIndex, x, y0, y1)

Inserts a collection of X, Y0 and Y1 points at the specified index, automatically triggering a redraw

startIndex: The index to insert at
x: The X-values
y0: The Y0-values
y1: The Y1-values

RemoveAt

public override void RemoveAt(int index)

xyyDataSeries.RemoveAt(index)

Removes the X,Y values at the specified index

index: The index to remove at

RemoveRange

public override void RemoveRange(int startIndex, int count)

xyyDataSeries.RemoveRange(startIndex, count)

Removes a range of points starting from the specified index

startIndex: Starting index of the range of elements to remove
count: The number of elements to remove

ToHitTestInfo

public override HitTestInfo ToHitTestInfo(int index)

result = xyyDataSeries.ToHitTestInfo(index)

When overridden in a derived class, returns a HitTestInfo struct containing data about the data-point at the specified index

index: The index to the DataSeries

Returns: The HitTestInfo

ToPointSeries

public override IPointSeries ToPointSeries(ResamplingMode resamplingMode, IndexRange pointRange, int viewportWidth, bool isCategoryAxis, bool? dataIsDisplayedAs2D, IRange visibleXRange, IPointResamplerFactory factory, object pointSeriesArg)

result = xyyDataSeries.ToPointSeries(resamplingMode, pointRange, viewportWidth, isCategoryAxis, dataIsDisplayedAs2D, visibleXRange, factory, pointSeriesArg)

Converts the default YValues to an IPointSeries which is used to render XY series

resamplingMode: The desired ResamplingMode
pointRange: The integer Indices range in the parent data-set
viewportWidth: The current width of the viewport
isCategoryAxis: If true, uses the indices to form the resampled X-values, else uses the X-Values themselves
