Hello,
please check the following code:
Code: Select all
<!DOCTYPE html>
<head>
<title>Bar Transparency</title>
<script type="text/javascript" src="https://www.steema.com/files/public/teechart/html5/latest/src/teechart.js"></script>
<script type="text/javascript">
function draw() {
var Chart1=new Tee.Chart("Canvas1");
Chart1.title.text="Bar Transparency";
var Series1=Chart1.addSeries(new Tee.Bar());
Series1.colorEach="no";
Series1.format.fill="rgba(243,156,53,0.05)";
Series1.data.values=[10,5];
Series1.data.x=[1,2];
Series1.marks.visible=true;
Series1.format.gradient.visible=false;
Chart1.draw();
}
</script>
</HEAD>
<BODY onload="draw()">
<canvas id="Canvas1" width="800" height="600">
This browser does not seem to support HTML5 Canvas.
</canvas>
</BODY>
</HTML>
The bar borders and the marks do not apply the transparency. Check it, please.
Thanks in advance and best regards,
MS

There are different properties for the series brush (format.fill), the series pen (format.stroke.fill), marks (marks.format.fill) and marks shadow (marks.format.shadow.color). Ie:
Code: Select all
var transp = 0.5;
Series1.format.fill="rgba(243,156,53,"+transp+")";
Series1.format.stroke.fill="rgba(0,0,0,"+transp+")";
Series1.marks.format.fill = "rgba(245,245,220,"+transp+")";
Series1.marks.format.shadow.color="rgba(80,80,80,"+transp+")";
