I have loaded two different data pie chart in a single page.I have used two
different selecthandler function for two pie charts to get the slice name.
But when i select first pie chart slice i am getting second chart slice
name.Whats the problem?
first chart selecthandler function
google.visualization.events.addListener(mychart1,'select',selectHandler1);
function selectHandler1() {
var selection1 = mychart1.getSelection();
var message = '';
for (var i = 0; i < selection1.length; i++) {
var item = selection1[i];
if (item.row != null && item.column != null) {
var str1 = data.getFormattedValue(item.row, item.column);
message += '{row:' + item.row + ',column:' + item.column + '} =
' + str1 + '\n';
}
else if (item.row != null) {
var str1 = data.getFormattedValue(item.row, 0);
message += '{row:' + item.row + ', column:none}; value (col 0)
= ' + str1 + '\n';
}
else if (item.column != null) {
var str1 = data.getFormattedValue(0, item.column);
message += '{row:none, column:' + item.column + '}; value (row
0) = ' + str1 + '\n';
}
}
if (message == '') {
message = 'nothing';
}
alert(str1);
}
second chart selecthandler function
google.visualization.events.addListener(mychart2,'select',selectHandler2);
function selectHandler2() {
var selection2 = mychart2.getSelection();
var message = '';
for (var i = 0; i < selection2.length; i++) {
var item = selection2[i];
if (item.row != null && item.column != null) {
var str2 = data.getFormattedValue(item.row, item.column);
message += '{row:' + item.row + ',column:' + item.column + '} =
' + str2 + '\n';
}
else if (item.row != null) {
var str2 = data.getFormattedValue(item.row, 0);
message += '{row:' + item.row + ', column:none}; value (col 0)
= ' + str2 + '\n';
}
else if (item.column != null) {
var str2 = data.getFormattedValue(0, item.column);
message += '{row:none, column:' + item.column + '}; value (row
0) = ' + str2 + '\n';
}
}
if (message == '') {
message = 'nothing';
}
alert(str2);
}
