Can you display multiple date ranges on the same chart?

[Kurt Peters]

Is it possible to display two data series on the same chart when using the Easy Dashboard library? Ideally what I'd like to be able to do is show two different date ranges on the same chart (basically what the "Compare to:" does within Google Analytics).

Hi,

Currently not using this ez-daah-library.

Today the API only allows you to query for a single date range, and each chart only displays a single query.

To solve this using this library would require you issue 2 queries, join them in a single data table, then visualize using multiple axis.

That's what I figured (although I was secretly hoping I was just missing something). Thanks for the response!

I'm going to tag onto this because it's vaguely related:

I have a function defined (let's calling it "combineData") that will join the results from two different queries (and then display the resulting array on a chart). The issue that I'm running into now is that I can not for the life of me, get this "combineData" function to wait until the two query functions have returned results. I have tried a separate async library, I've tried jQuery's deferred "$.when.done()", but nothing works. I defined callback functions for the two GADash functions, and then even tried calling them [e.g. $.when(visitors1(callbackfunc), visitors2(callbackfunc)).then(combineData);].

With everything I've tried, it always executes the two GADash functions and then, without waiting for those two functions to actually return a result, the combineData() function. What am I missing?

You need to synchronize the two async requests.

Set up a counter for the number of requests.

Create a single callback that both async requests call.

In the call back, increment the counter. If the counter < number requests, save the data, if counter == number of requests, do something with all the data.

Of course there are a bunch of clever ways to make this generic.

Thank you! It finally works!
