Controlling the colors of a BIRT Pie Chart

[ahoneycutt0929]

I have read several older posts on the code to control the color of each pie slice and I have tried the code of each one I found and nothing is working for me.

I do not know Java so please be nice.

I have tried using this code that I found on this forum.

function beforeDrawDataPoint( fcdph, fill, fcsc )
{
if (fcdph.getBaseDisplayValue() == "Total Cash"){
fill.set(0,140,153);
}
//else if (fcdph.getDataPointHints().getBaseDisplayValue() == "Total Equity"){
//fill.set(112,204,211);
//}
//else if (fcdph.getDataPointHints().getBaseDisplayValue() == "Total Benefits"){
//fill.set(255,78,0);
//}
else{
fill.set(255,78,0);
}
}

What should be the field listed in quotes? Nothing I have tried works.

I have my series field which is an Amount field, my Category which is a text field.

I want to control the slice colors by the different category names. I only have 3 as seen above. Is this the correct code to accomplish this? If so, what am I missing.

I have also tried using this code;

function beforeDrawDataPoint( dph, fill, icsc )
{
var stateKey = dph.getBaseDisplayValue();
if(stateKey.contains('Total Cash'))
{
fill.set(0, 140, 153);
} // Set to RED
else if(stateKey.contains('Total Equity'))
{
fill.set(112, 204, 0);
} // Set to Green
else if(stateKey.contains('Total Benefits'))
{
fill.set(255, 78, 0);
} // Set to Black
else
{
fill.set(0, 0, 64);
}// Set to Blue
}

I have loaded this code into the OnRender Script of the chart. Should it be someplace else?

Any help you can provide would be very appreciated.

I am using the most recent version of Eclipse.

I am simply want to control the colors of the slices and not have BIRT randomly pick a color from the palette.

Thanks in advance.

In this report based on the included "Classic Models" database we set the color for "Trains" to black - for the pie chart itself and for the labels. HTH

Thank you so much for this info. I am pulling my data from a scripted data set and I have 3 columns, Type, Worker, Amount. My pie series is Amount and my category is the Type field, no grouping. I am not using a legend. In the Type field I have values such as "Total Cash", "Total Equity" and "Total Benefits". The pie is producing correctly for each amount value. Using your code I am still not seeing a difference in the colors. I have this code on the OnRender of the pie chart. I am not getting any errors. Does anyone see anything wrong with this code? Any ideas why it would not render? The only difference I can see is that I am using a Scripted data set and you are not. function beforeDrawDataPoint(dph, fill, icsc) { var scriptable = icsc.getExternalContext().getScriptable(); var s=dph.getBaseDisplayValue(); if(s == "Total Cash") { fill.set(0, 140, 153); } // Set to GREEN else if(s == "Total Equity") { fill.set(112, 204, 0); } // Set to Light Green else if(s == "Total Benefits") { fill.set(255, 78, 0); } // Set to Orange else { fill.set(0, 0, 64); }// Set to Blue } I truly appreciate any help on this.

I am very happy to say that I got it to work. I found a setting on the category series that had the minimum slice set to category and 2. Removing that and setting it to Minimum Slice Value =0 fixed the issue. Thank you again for all your help.
