Filled Line Graph

suria...@gmail.com (Evan Stern) — Mon, 04 Jan 2010 17:42:52 UT

I'm sure that this has been touched upon before but I didn't see any
posts about it so I'll ask:
I'm trying to generate a line graph with multiple data sets and I
would like to have different colors fill the gaps between the data
sets. So, if my first data set creates (for simplicity's sake) a
straight line at y=4 then I'd like to have y=0 to y=4 colored in blue.

UrlEncoding issue for multilanguage data output

bruno.br...@gmail.com (bruno.braga) — Fri, 01 Jan 2010 17:59:39 UT

I would like to report issues with use of special chars on text
rendering. I could not find in the documentation any specifications
that leads to limitations on this part.
The issue:
When I print special chars (alphabetic with accent, like in portuguese
language), it works fine:

I spoke too soon. The special chart type for the maps apparently
accepts URI -encoded unicode chars, but NOT the regular chart API. If
we try, for example, to use the value %e2%99%86 (Neptune) as the
symbol to be plotted, the entire annotation list is not displayed at
all. Only the "main" data set shows up. The chart API does accept

Thanks! I will post to the "Call For Charts" thread when my planet &
star chart app has been updated.

Re: Too many chm points on line charts?

benb...@gmail.com (ben) — Tue, 29 Dec 2009 20:08:32 UT

Hmm, thanks for the tip. Unfortunately i'm using the charts4j API ,
which seems to have this marker code hard coded to do the "chm=d,
0000FF,0,-1,4,0" version. I'll try to add this thread as an issue for
that project.
Thanks!

Re: Mapping out Google Group Usage

kbornho...@gmail.com (KeithB) — Tue, 29 Dec 2009 16:00:04 UT

Your CHXL parameter contains invalid data: "chxr=....end of range|>".
Removing that displays a pretty nice chart, but you'll probably want
to increase the step-size for your x-axis labels (e.g.
chxr=0,0,500,25).
I'm not sure of the underlying data, but you're using simple encoding
which means the data (and chart) ranges from 0--61 so you'll need to

The Chart API expects URL-encoded UTF-8 characters. See the examples
at [link]
Here's a site that I've used in the past to obtain utf-8 hex values:

Take a look at this older thread

and try something like: "chm=d,0000FF,0,0:1000:-1,4,0"

Re: Line X-Y Chart: Chart not displaying properly

kbornho...@gmail.com (KeithB) — Mon, 28 Dec 2009 15:07:19 UT

Hi,
Now it's just a matter of scaling your data. Charts using text-encoded
data range expect data values between 0 and 100. Your CHXR parameter
changes the Y-Axis labels, but does nothing with the underlying data.
Add "chds=0,100,0,49" to tell the API that your first dataset (x
values) ranges from 0 to 100 and your second data set (y values)

Too many chm points on line charts?

benb...@gmail.com (ben) — Fri, 25 Dec 2009 19:22:24 UT

I am having a problem with adding chm markers to my line charts. In
the example below , i have a line chart with 500 values. The URL does
not appear to be too long, since the line itself draws fine. But only
about the first half of the markers are drawn correctly. Is there some
kind of maximum to the number of chm markers that will be drawn??
