wrap x-axis label

red4m

<p>How can I wrap the Label on the x-axis after max. 15 characters. Or after "-" , "/", " ". I dont want to cut the <strong>words in the middle</strong>.<br>
 <br>
Cutting after 15 characters:</p>
<p><strong> </strong></p>
<pre class="_prettyXprint">
function beforeDrawAxisLabel( axis, label, icsc
){var tst =
label.getCaption().getValue();var wrap =
15;var repeat = Math.floor(tst.length() /
wrap);var str =
tst; if(repeat > 0){str =
""; for(i = 0; i < repeat; i++){str +=
tst.substring((i*wrap),((i+1)*wrap-1))+"\r\n";}if((tst.length()
% wrap) > 0){str +=
tst.substring((i*wrap-1),tst.length());}} label.getCaption().setValue(str);}</pre>
<p>Any ideas or same Problems?</p>

<p>You could do something like this:</p>
<pre class="_prettyXprint _lang-js">
function beforeDrawAxisLabel( axis, label, icsc )
{
var tst = label.getCaption().getValue();
var wrap = 15;
var repeat = Math.floor(tst.length() / wrap);
var str = tst;
if(repeat > 0){
for(i = 0; i < repeat; i++){
var tempString = str.substring(0, ((i+1)*wrap-1));
var lastSpace = tempString.lastIndexOf(" ");
var lastDash = tempString.lastIndexOf("-");
var lastSlash = tempString.lastIndexOf("/");
if(lastSpace > lastDash && lastSpace > lastSlash){
str = str.substring(0, lastSpace) + "\r\n" + str.substring(lastSpace, str.length());
}else if(lastDash > lastSpace && lastDash > lastSlash){
str = str.substring(0, lastSpace) + "\r\n" + str.substring(lastDash, str.length());
}else if(lastSlash > lastSpace && lastSlash > lastDash){
str = str.substring(0, lastSpace) + "\r\n" + str.substring(lastSlash, str.length());
}
}
}
label.getCaption().setValue(str);
}
</pre>
