Preventing Motion Chart Interpolating Data

[rd-london]

Hi,

Is it at all possible to prevent the Motion Chart from interpolating
results?
At all, in any way?

Thanks,
R

Hello again,
Only me .... I see no-one replied to this, which is a great shame.

The Motion Chart visualisation is full of wonder, it's a great thing -
and Hans Rosling (http://en.wikipedia.org/wiki/Hans_Rosling), the man
who originated this I think, is terrific - his TED talk where he
swallows swords is truly a beautiful thing.

Given such beauty, it is a great shame that the Motion Control seems
to *ALWAYS* interpolate results - it's so annoying! Is there
absolutely no way I can set a setting, flick a switch, raise a flag -
do something - to stop it doing this?

If there isn't, couldn't you just squeak this little tiny request into
the next rollout? Go on, you know you want to .... It would be as
simple as:

"interpolate: True", or even "interpolate: False"

Thanks,
R

I'm not sure I understand what exactly you want to happen when setting "interpolate: False".

Are you talking only about the bubbles view?

Today, if you use a daily scale, with data points one month apart from each other, then motionchart will create intermediate data points by linear interpolation.

When setting "interpolate: False" do you want the bubbles to "jump" when the data changes, instead of moving smoothly?

Hi,
Many thanks for responding, apologies for taking so long to reply.
Yes, I'm only talking about the bubbles view.

If "interpolate:False" is switched on, then the bubbles only actually
*appear* when there is data. This may seem odd, and you may think that
the resulting experience may be ugly - however it would then be
truthful. The beauty aspect is irrelevant when you're actually looking
for this chart (which I do utterly love btw, I think it's a thing of
genius) to represent the truth behind the statistics.

So the result would be that bubbles would appear and disappear.

Thanks,
R

Hello again,
I actually have another request.

It is possible to use the Google Motion Chart as a highly
sophisticated bubble chart by setting the data to span just one date,
a placeholder, meaningless date. This is really useful.

But with one downside: the one single date appears beneath the x-axis,
and if the date is purely a placeholder, then it's quite an eyesore -
and one has to put up supporting copy explaining that the date is
actually meaningless.

So it would also be useful to configure the Google Motion Chart such
that the dates/time, if there is only one date, is not shown beneath
the x-axis.

Many thanks,

Cheers
R

Wouldn't be easier to customize the existing scatter plot to behave like a bubble chart? (you'd need a separate serie for each bubble size/color combination however, which could make the datatable and options set a little ugly).

Hi.. Have you found a solution.

I need the motion chart to go from 01jan to 01feb to 01mar and so on... without interpolating data.

also... when I track the bubble... it should have (1) ----- (2) ----- (3)  and so on.. in stead of continous bubbles.

please advise.

I found the solution myself...  

Make 2nd Column look like this: "yyyy-mm"

2011-01

2011-01

2011-01

2011-02

..

..

and so on... and this way... the Chart shows Jan 2011, Feb 2011, Mar 2011 and so on for the time line... and it doesn't interpolate every single day of the month.. but jump from month to month.

Further comment... there seems to be a bug or missing feature in motion chart to let the chart have initial state... you can only set the initial state when you create the chart. So, if you have already created the chart... and you have copied the stateinfo from the bottom right wrench icon, advanced and copy the text... you can't do anything with it...

You will have to keep the text copied... delete chart... and insert gadget... and choose motion chart.. 

then in the default state... paste this text in the box. this will work.

Also.. using Insert Chart -> Motion Chart... doesn't have this default state text box... So, only option is to use Insert Gadget... and I don't know what Google is going to do with Gadgets in Year 2013... as this feature is not available in insert chart.

Hope google fixes this... and if anyone find the above comments helpful... please remember to post your comments here.

Hi there,

Have you been able to avoid interpolation in motion charts eventually? I have the same issue here.

Thanks,

Hello, 

Everything is nice in Motion chart except interpolation!

Have you an idea about how to avoid interpolation or even not to show the time player?

Thanks!
