Class Detail

Tee.Chart.Axis(chart, horizontal, otherSide)

Parameters:
{Tee.Chart} chart: The chart object this axis object belongs to.
{Boolean} horizontal: Determines if axis is horizontal or vertical.
{Boolean} otherSide: Determines if axis is at top/right or bottom/left side of chart.

Field Detail

{Tee.Format} format

Visual properties to draw the axis line.

{Tee.Chart.Axis-Grid} grid

Properties to display grid lines at tick increments.

{Tee.Chart.Axis-Ticks} innerTicks

Properties to display tick lines at each increment, inside chart.

{Tee.Chart.Axis-Labels} labels

Properties to display axis labels at tick increments.

{Tee.Chart.Axis-Ticks} minorTicks

Properties to display small tick lines between ticks.

{Tee.Chart.Axis-Ticks} ticks

Properties to display tick lines at each increment.

{Tee.Chart.Axis-Title} title

Properties to display text that describes the axis.

Method Detail

<inner> {Number} anySeriesHasLessThan(c, n)

Parameters:
c
n

Returns:: {Number} Returns if any visible series has less than n values. Only called from Axis calcIncrement, to avoid axis label increments to be smaller than series number of points.

{Number} calc(value)

Parameters:
value

Returns:: {Number} Returns the position in pixels for a given value, using the axis scales.

calcAxisScale()

<inner> {Number} calcIncrement(c, maxLabelSize)

Parameters:
c
maxLabelSize

Returns:: {Number} Returns the best appropiate distance between axis labels.

calcMinMax(p1, p2)

Parameters:
{Number} p1: Position in pixels to be axis minimum.
{Number} p2: Position in pixels to be axis maximum.

calcScale()

{Number} calcSize(value)

Parameters:
value

Returns:: {Number} Returns the size in pixels of a given value, using the axis scales.

<inner> calcWordWrap(f, s)

Parameters:
f
s

checkMinMax()

drawAxis()

drawGrids()

drawLabel(value, r)

Parameters:
value
r

drawLabels()

drawTicks(t, factor, mult)

Parameters:
t
factor
mult

drawTitle()

{Number} fromPos(p)

Parameters:
p

Returns:: {Number} Returns the axis value for a given position in pixels.

fromSize(p)

Parameters:
p

{Boolean} hasAnySeries()

Returns:: {Boolean} Returns the first visible series associated to this axis, or null if any.

{Number} minmaxLabelWidth(adjust)

Parameters:
adjust

Returns:: {Number} Returns the approximated width in pixels of largest axis label.

<inner> {Number} nextStep(value)

Parameters:
value

Returns:: {Number} Returns the next bigger value in the sequence 1,2,5,10,20,50...

rotatedWidth(l, w)

Parameters:
l
w

{Number} roundMin()

Returns:: {Number} Returns the axis minimum value rounded according the axis increment distance.

scroll(delta)

Changes the axis maximum and minimum values

Parameters:
{Number} delta: The positive or negative amount to scroll.

setMinMax(min, max)

Parameters:
min
max

<inner> toRadians(angle)

Parameters:
angle

<inner> truncFloat(n)

Parameters:
n
