This method enables a specified custom IMarker to update it's content every time the IMarker is redrawn. @param e The Entry the IMarker belon

Releases the drawing bitmap. This should be called when {@link LineChart#onDetachedFromWindow()}.

Removes the first Entry (at index 0) of this DataSet from the entries array. Returns true if successful, false if not. @return

Resets all colors of this DataSet and recreates the colors array.

Saves the current Matrix state and the touch-start point. @param event

Sets the radius of the drawn circles. Default radius = 4f, Min = 1f @param radius

Deceleration friction coefficient in [0 ; 1] interval, higher values indicate that speed will decrease slowly, for example if it set to 0, it will sto

set this to true to enable the drawing of circle indicators for this DataSet, default true @param enabled

set this to true to draw the pie center empty @param enabled

sets whether the legend will draw inside the chart or outside @param value

Sets extra offsets (around the chart view) to be appended to the auto-calculated offsets. @param left @param top @param right @param bottom

Set a minimum interval for the axis when zooming in. The axis is not allowed to go below that limit. This can be used to avoid label duplicating when

sets the horizontal alignment of the legend @param value

Sets the last highlighted value for the touchlistener. @param highs

sets the marker that is displayed when a value is clicked on the chart @param marker

Sets the maximum scale factor for the x-axis @param xScale

Sets the maximum scale factor for the y-axis @param yScale

Sets the minimum and maximum scale factors for the x-axis @param minScaleX @param maxScaleX

设置x缩放的最小最大值

Sets the minimum width that the axis should take (in dp). @param minWidth

Returns the drawing mode for this LineDataSet @return

Set the phases used for animations. @param phaseX @param phaseY

sets the distance the highlighted piechart-slice of this DataSet is "shifted" away from the center of the chart, default 12f @param shift

Sets extra spacing for `axisMaximum` to be added to automatically calculated `axisMaximum`

Sets extra spacing for `axisMinimum` to be added to automatically calculated `axisMinimum`

Sets a list of colors to be used as the colors for the drawn values. @param colors

sets the vertical alignment of the legend @param value

Sets the y-value for the Entry. @param y

Sets up the formatter with a given number of decimal digits. @param digits

returns the distance between two pointer touch points @param event @return

Calls the OnChartGestureListener to do the start callback @param me

Post-scales by the specified scale factors. @param scaleX @param scaleY @return

Adds a new color to the colors array of the DataSet. @param color

Animates the rendering of the chart on the x-axis with the specified animation time. If animate(...) is called, no further calling of invalidate() is

Created because Arrays.asList(...) does not support modification. @param array @return

Performs auto scaling of the axis by recalculating the minimum and maximum y-values based on the entries currently in view.

calculates the needed angle for a given value @param value @return

calculates the needed angles for the chart slices

Calculates the total number of entries this DataSet represents, including stacks. All values belonging to a stack are calculated separately.

calculates the maximum stacksize that occurs in the Entries array of this DataSet

Calculates the dimensions of the Legend. This includes the maximum width and height of a single entry, as well as the total width and height of the Le

Removes all DataSets (and thereby Entries) from the chart. Does not set the data object to null. Also refreshes the chart by calling invalidate().

Sets the alpha component of the given color. @param color @param alpha 0 - 255 @return

Combine arrays. @param arrays @return
