Returns a recyclable MPPointF instance.
Sets the color of the center text of the PieChart.
Returns the offset on the x- and y-axis the center text has in dp.
Sets the offset the center text should have from it's original position in dp. Default x = 0, y = 0

Returns the rectangle that defines the borders of the chart-value surface (into which the actual values are drawn).
Returns the animator responsible for animating chart values.
returns the diameter of the pie- or radar-chart
returns an integer array of all the different angles the chart slices have the angles in the returned array determine how much space (of 360°) each slice takes
Sets the color the entry labels are drawn with.
Sets the size of the entry labels in dp. Default: 13dp
Sets a custom font for the drawing of the entry labels.
Sets extra offsets (around the chart view) to be appended to the auto-calculated offsets.
Returns true if there are values to highlight, false if there are no values to highlight. Checks if the highlight array is null, has a length of zero or if the first object is null.
Sets the color for the hole that is drawn in the center of the PieChart (if enabled).
Returns the size of the hole radius in percent of the total radius.
sets the radius of the hole in the center of the piechart in percent of the maximum radius (max = the radius of the whole chart), default 50%
ProtectedlastSets the last highlighted value for the touchlistener.
Returns true if the chart is empty (meaning it's data object is either null or contains no entries).
Sets the max angle that is used for calculating the pie-circle. 360 means it's a full PieChart, 180 results in a half-pie-chart. Default: 360
min 90, max 360
The minimum angle slices on the chart are rendered with, default is 0.
minimum angle for slices
Set the angle to set minimum size for slices, you must call #notifyDataSetChanged() and #invalidate() when changing this, only works if there is enough room for all slices to have the minimum angle.
minimum 0, maximum is half of #setMaxAngle
Sets the color of the no data text.
Sets the typeface to be used for the no data text.
Returns the radius of the chart in pixels.
gets the raw version of the current rotation angle of the pie chart the returned value could be any value, negative or positive, outside of the 360 degrees. this is used when working with rotation direction, mainly by gestures and animations.
ProtectedrequiredReturns the base offset needed for the chart without calculating the legend size.
ProtectedrequiredReturns the required offset for the chart legend.
gets a normalized version of the current rotation angle of the pie chart, which will always be between 0.0 < 360.0
Set an offset for the rotation of the RadarChart in degrees. Default 270 --> top (NORTH)
Returns true if rotation of the chart by touch is enabled, false if not.
Set this to true to enable the rotation / spinning of the chart by touch. Set it to false to disable it. Default: true
Sets the amount of transparency the transparent circle should have 0 = fully transparent, 255 = fully opaque. Default value is 100.
