Pie slice must remain exploded until another pie slice is clicked

divyani

<p>Hi,</p>
<p> </p>
<p>I have two pie charts in my report. The first chart displays the number of customers by country. When i click a pie slice on the first chart, country name is captured(inside Y series client scripts) and a filter is applied on the second chart to show the number of customers by city for that country..</p>
<p> </p>
<p>When the above is done, the first chart is also re rendered even though there is no change associated with it. Can this be avoided?</p>
<p> </p>
<p>One more question is, when i click on a pie slice on the first chart, the slice has to remain exploded until i click on another slice of that chart so that the user gets a clear understanding about the drill down that is happening. </p>
<p> </p>
<p>Please find the sample report attached.</p>
<p> </p>
<p>Thanks in advance!</p>

<p>The chart appears to be re-rendered because the animation is enabled.  Can you turn it off?  If you need animation for the first time, you can set to true, and then have a flag to turn it off for subsequent clicks.</p>
<p> </p>
<p>The pie slice can be exploded if you add a variable to save the last state in the click (<span style="font-family:'courier new', courier, monospace;">categoryDataClicked = categoryData;</span>), and then in the <em>beforeDrawDataPoint </em>event, you can check for that point and explode that slice.</p>
<pre class="_prettyXprint">
beforeDrawDataPoint: function(point, pointOptions, chart, seriesIndex, pointIndex)
{
if (point.name == categoryDataClicked)
{
    point.slice();
}
},</pre>
<p>See attached for the revised sample.</p>
