Hi,
We are using Chart Directory5.0 based on my requirement; Pie diagram is working fine
based on my input data. But we are passing the data 0% for particular label(ex: Labor is
0%). our requirement 0% data label is not displaying in the chart. But our below code
0% data related label also appearing.
Can you please help me how to disable the 0% data related label in the chart.
<%@page import="ChartDirector.*" %>
<%
// The data for the pie chart
double[] data = {0, 0, 20, 20, 20, 20, 20};
// The labels for the pie chart
String[] labels = {"Labor", "Licenses", "Taxes", "Legal", "Insurance", "Facilities",
"Production"};
// Create a PieChart object of size 360 x 300 pixels
PieChart c = new PieChart(360, 300);
// Set the center of the pie at (180, 140) and the radius to 100 pixels
c.setPieSize(180, 140, 100);
// Set the pie data and the pie labels
c.setData(data, labels);
// Output the chart
String chart1URL = c.makeSession(request, "chart1");
// Include tool tip for the chart
String imageMap1 = c.getHTMLImageMap("", "",
"title='{label}: US${value}K ({percent}%)'");
%>

Hi basamp,
You may use one of the following method:
(a) Instead of 0, please use Chart.NoValue. In ChartDirector, the value of 0 will be displayed as 0, while Chart.NoValue will not be displayed.
For example:
double[] data = {Chart.NoValue, Chart.NoValue, 20, 20, 20, 20, 20};
or
//change 0 into Chart.NoValue
for (int i = 0; i < data.lenght; ++i)
if (data[i] == 0) data[i] =Chart.NoValue;
(b) Alternatively, you may consider not to pass the 0 values to ChartDirector (eg. remove them from the data arrays before passing the data to ChartDirector).
Hope this can help.
Regards

Hi basamp,
I think the following code in my previous post is already disabling the 0% label dynamically, because it dynamically replaces zero values with Chart.NoValue;
//change 0 into Chart.NoValue
for (int i = 0; i < data.lenght; ++i)
if (data[i] == 0) data[i] =Chart.NoValue;
Hope this can help.
