Pentaho CCC/CDE tool Extension points.
Pentaho CDE tool, Extension points are very useful feature. You can treat this extension points as a advance setting or property of CCC Bar/Pie/any chart. By setting this extension points you can achieve the below sample thing, yes off course list is too much so we are not mentioning all of this.

n Change X axis label fonts , COLOR , alignment (vertical , diagonal).
n Same way you can change the Y axis lables/fonts.
Problem1: How can I rotate x axis labels diagonally in CCC Bar chart with help of extension points.
Solution: In CDE, Open the related CCC chart component, click on the “Advance Properties” of that component and select the extension points, it will open the one popup window , Add below extension point to rotate the x Axis lables.
Arg0: xAxisLabel_textAngle Val0: -0.8
Arg1: xAxisLabel_textAlign Val1: right
Please note that we have provided here angle of -0.8 (negative 0.8) , you can customize your angle as per your need. if you are working on CDA not through CDE , then you need to add the extention point with above 2 argument as shown below.
var render_top_load_chart = {
..........
extensionPoints: [["xAxisLabel_textAngle","-1.3"],["xAxisLabel_textAlign","right"]]
}
Problem2: How can set Y axis fonts and color of labels.
Solution: In CDE, same way set below extension points ,
Arg0: xAxisLabel_font Val0: 13 px Arial
Arg1: xAxisLabel_textStyle Val1: blue
We can set the number of extension point for setting Advance Property of the CCC Component.
