Figuring out where on a chart I clicked

Hello,

I have been building charts using SPARK UI coach views. So far I have played with the Donut and Pie charts and they work well, especially when I figured out how to use a Configuration option to supply the data series. I see that there is an ‘on Click’ event available. Is there a way to figure out where on a chart I clicked? For example, my pie chart shows distribution of activity across US States – 1 pie segment for each included state. Is there a way to capture which state/pie segment was clicked on?

Thanks

Hi Stuart,

Quick question, what exactly are you trying to accomplish when clicking on a pie segment. Are you trying to just see what “State” is associated with that section or are you trying to do something with the selected data.

Hello Isaiah,

My first thought is that I would use the information on which chart segment was selected to affect some other coach view on the page. Let’s suppose, for example, that I have a pie chart (with states) and a Table CV, one of whose columns is the state. I would like to search (filter) the table based on the pie segment that I click on and only show rows for that state. That’s just one example. If I can get the information then there’s probably lotsa other things that I might use this for in subsequent projects.

Now, it may be that I am touching on the dimensional analysis capabilities of the chart, though clearly not using the full capabilities. If that’s the case, then i will need to go read up on that. I just wondered if there is some value that’s early usable to tell me where I clicked.

Thanks

Stuart:

As far as I can tell there is no public method/property that gives us this data.  I will comb thru the private methods to see if I can find something.

I knew I had done this, but I used a private property.  I will lobby for a method that will return the information.  The data that I have is this:

l<span class=”name”>abel</span><span class=”object-properties-section-separator”>:</span><span class=”value object-value-string”>”Category 3″
</span><span class=”name”>value</span><span class=”object-properties-section-separator”>:</span><span class=”value object-value-number”>23</span>

This gives you the category you clicked on and it’s value.

Hello,

I just downloaded SPARK 4.4.0.1 EE on BPM 8.5.7. I tried out the new getSelectedDataPoint() method that’s now available for chart controls. It does exactly what I needed, addressing my need documented above. (It also got me wondering for a how to reset a Table and I found the clearSearch() method.)

Thanks for being so responsive!
