function to manually set line color

Gordon — Sun, 23 Sep 2007 13:45:03 -0000

Manually specify line color with the addLine and addCurve methods

wtLineChart.prototype.addCurve = function(ptList, _color)
{
if (ptList.length<3)
throw "wtLineChart::addCurve(): the length of ptList should be greater than or equal to 3";
if (_color.length<3)
throw "wtLineChart::addCurve(): color should be a string greater than or equal to 3";
this.add("curve",ptList,_color);
}

also modified private function .add

wtLineChart.prototype.add = function(_type,ptList,_color)
{
var domNode = $_(this);

// if user passed a color string, either grab an autogenerated color
// or store the user color as a wtColor object in the color array
if (_color=="auto" || _color=="")
{
var color = domNode.colorGen.colorArray[domNode.path_.length].toString();
}
else
{
var color = _color;
domNode.colorGen.colorArray[domNode.path_.length] = new wtColor(_color);
}

function to set font weight

Gordon — Sun, 23 Sep 2007 13:41:46 -0000

font color and font style have functions, but nothing for font weight (normal or bold).

(in wt_vector.js, wtText)

/**
Sets the font weight of the text
@param {String} _weight The font style ( normal, bold )
*/
wtText.prototype.setFontWeight = function(_weight)
{
_weight = _weight.toLowerCase();
if (!(_weight == "normal" || _weight == "bold"))
throw "wtText::setFontWeight(): the font weight should be 'normal' or 'bold'";

var domNode = $_(this);
if (isMSIE())
{
this.get("divNode").get("style").fontWeight = _weight;
}
else
{
domNode.setAttribute("font-weight",_weight);
}
}

method to reposition wtText object via javascript

Gordon — Sun, 23 Sep 2007 13:39:54 -0000

Not sure if this is the proper way to move a wtText object once it has been created, but I couldn't see any other easy way to do it.

(added to wt_vector.js)

New function for the wtText prototype:
/**
Sets the x,y location of the text
@param {Number,Number} x,y The x and y location
*/
wtText.prototype.setXY = function(_x,_y)
{

if (isMSIE())
{
this.get("divNode").get("style").left = _x;
this.get("divNode").get("style").top = _y;
}
else
{
$_(this).setAttribute("x", _x);
$_(this).setAttribute("y", _y);
}
}
