Try this (not tested):

<pre><code>&lt;p:barChart extender="ext" id="horizontal" value="#{chartBean.categoryModel}" legendPosition="se" style="height:300px" 
 title="Horizontal Bar Chart" orientation="horizontal"/&gt;
</code></pre>

In you js add this

<pre><code>function ext() {
 this.cfg.seriesDefaults = { 
 useSeriesColor: true, 
 min: 0, 
 max: 200, 
 tickInterval: 20, 
 tickOptions: { 
 formatString: '%d' 
 } 
 };
}
</code></pre>

or this x axis only :

<pre><code>function ext() {
 this.cfg.axes = {
 xaxis:
 {
 tickInterval: 20,
 tickOptions: { 
 formatString: '%d' 
 } 
 }
 };
}
</code></pre>

You can try playing with <code>tickInterval</code>...

Extender

Charts provide high level access to commonly used jqplot options however there are many more
customization options available in jqplot. Extender feature provide access to low level apis to do
advanced customization by enhancing this.cfg object, here is an example to increase shadow depth
of the line series;

<pre><code>&lt;p:lineChart value="#{bean.model}" extender="ext" /&gt;


function ext() {
 //this = chart widget instance
 //this.cfg = options
 this.cfg.seriesDefaults = {
 shadowDepth: 5
 };
}
</code></pre>

Refer to jqPlot docs for the documentation of available options;

your extender function could be like this

<pre><code> function customExtender() {
 this.cfg.axes.xaxis.tickOptions = {
 formatString : '%d'
 };
 this.cfg.axes.xaxis.tickInterval = 1;
 }
</code></pre>

I had the same problem and this works great, I based on Daniel's Answer and some other code. This way it just format the desired axis, not both.

blocks|key|282280|text|您可以使用以下代码在@ManagedBean类中将格式设置为axis：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|282281|Axis+xAxis+=+categoryModel.getAxis(AxisType.X);
xAxis.setTickFormat("%25.0f");|code-block|syntax|javascript|282282|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can set format to axis from your @ManagedBean class using the following code:

<pre><code>Axis xAxis = categoryModel.getAxis(AxisType.X);
xAxis.setTickFormat("%.0f");
</code></pre>

I have p:barchart graph in my application similar to the second barchart on the showCase:
<a href="http://www.primefaces.org/showcase/ui/barChart.jsf" rel="nofollow">http://www.primefaces.org/showcase/ui/barChart.jsf</a>

<pre><code>&lt;p:barChart id="horizontal" value="#{chartBean.categoryModel}" legendPosition="se" style="height:300px" 
 title="Horizontal Bar Chart" orientation="horizontal" min="0" max="200"/&gt;
</code></pre>

how can I customize the Numbers on my X-axis. I want to format the x-axis to use only Integers.

thanks in advance.
