Best practice for dynamically modifying a report [message #652638]

Hi,

First let me start out by saying a big "thank you" for all the help you have been providing me recently.

Now for the question Wink

I have a Pie chart with data represented in items/second. I would like to add some form of interactivity that would allow the user to change the units to items/hour or items/day etc...

Obviously the math is easy to do in the script but I am looking for guidance as to:
1) the best way to interact with the user. Something like buttons to launch a script would do.
2) After changing the variable that would determine the units in the script I would need to refresh the report and I don't know how to do that easily.

Am I on the right track?

Mike,

I have written quite a bit about chart interactivity on Birtworld.

What you will probably need most is calling-client-side js and use that
in a combination with the report developed here:

Thanks Jason, these links are a goldmine... quick question though...

The script that reloads the page does so on a timer. How would I reference the function "reloadpage" manually from another script such as interactivity of an image button somewhere else in the report? For example a refresh button or just when the user changes a checkbox selection or something along those lines.

Just add a text element to the report that is set to html type and enter
something like this:

<INPUT type="button" value="Refresh" onclick="reloadpage()" />
