Why doesn't this Google Chart API URL render both data sets on this XY scatter plot?

I've read the documentation over and over again, and I can't figure it out.
First a point of clarification. You talk about a "XY scatter plot", but these are actually 2 distinct chart types in the Google Chart API. Your URL refers to cht=lxy parameter which is an XY line chart.
The first problem with your URL is your data parameter (chd). Since it is an XY line chart, data sets must be defined in pairs but I see an odd number of data sets (3).
Christian D's response is incorrect. There is no percentage requirement.
You may be better off using a wrapper API which abstracts away many of these ugly details.
I think it actually does render both data sets, but you can only se one of them because there's only one scale on the y axis. (In other words, 0.10 is too small to show.)
And, you should really be using percentages. 100 is the highest accepted value:
Where chart data string consists of positive floating point numbers from zero (0.0) to one hundred (100.0)

I developed the few Line charts for BMP280 sensor data in powerbi. This is one of the line chart for displaying the temperature value by time and device id.
But I want same line chart with different Color like this below image, whenever temperature value suddenly changes.
Can you please tell me is it possible to develop the Line chart with multiple colors?
If you're willing to consider a vertical bar chart instead of a line chart, you would be able to create a calculation for each row that determines whether the change is significant, potentially by comparing an aggregate of recent measurements to specific thresholds.
Once you do that, you would use this column's value as a legend for your visualization. So if a row has a value of "Significant Positive Change" (or something like that), the bar or bars showing that change can be red.
Your other alternative is to use an R-based visual, of which there are surely examples of this type of visualization. I'll update this answer if I find one that looks promising.
Instead of tending 1 data series, you can split it into 2 data series e.g. one with normal temperatures and one with high temperatures. Then you can just plot these in different colours. Just make sure that the ranges are same i.e. cannot be 'Auto'.
Hi frens I am using geopy to calculate the latitude and longitude. Now I want to get the list of areas given distance from a zipcode.How to get that?
Well, as I can see, geopy doesn't have any built-in capability to get a list of areas around some coordinates.
But you can use a workaround. Take your geocode and calculate coordinates (latitue and longitude). Then imagine a grid on the map with a cell size equal to area of the smallest one you need to find around your location.
Use geopy to get an area name belonging to the each cell corner of your grid. Is that ok for you? It will get you some kind of approximation because a grid is not a circle and you may miss some small areas. But I think in most cases the solution will work fine.
It is much easier to locate zipcodes inside a rectangle than in a circle so I would recommend that you approximate your problem by looking for zipcodes inside a given rectangle.
Here are answers to the question of how to get list of zipcodes in given polygone: Find zipcodes inside polygon shape using google maps api
Summary
You need geometry for each zipcode. Once you have that you need to be able to query it using database that supports geoquery. One such database is Google's Fusion Table and there is already a geometry data table for zipcodes available here: https://www.google.com/fusiontables/DataSource?docid=1AxB511DayCdtmyBuYOIPHIe_WM9iG87Q3jKh6EQ#rows:id=1
Here's the sample query for Fusion Table data.
Another approach is server side code using PHP and CSV data. Here's live demo: http://daim.snm.ku.dk/demo/zip/. The page also has download for code.
If you use any of above technique please make sure to upvote answers of original authors :).
It's possible to set the color values for a Google chart, but is it possible to get the preset color values for a chart? Is there an array that holds those values, that can be accessed?
From this Google Groups Discussion the default color array is not documented and cannot be accessed. However, if you want the array of colors, Xavier Gumara posted it, as did asgallant:
{"#3366cc","#dc3912","#ff9900","#109618","#990099","#0099c6","#dd4477","#66aa00","#b82e2e","#316395","#994499","#22aa99","#aaaa11","#6633cc","#e67300","#8b0707","#651067","#329262","#5574a6","#3b3eac","#b77322","#16d620","#b91383","#f4359e","#9c5935","#a9c413","#2a778d","#668d1c","#bea413","#0c5922","#743411"}
Just an FYI, a large portion of these sorts of questions have been covered on the Google Groups by folks like asgallant, and it can be worthwhile to do a quick search to try to find them (quicker than waiting for me to do it!). The above answer was the first two results for 'google visualization default colors'.
I have data for sin curves of differing magnitudes over time and I would like to combine all the curves into a single curve on a chart.
Is it possible to do this with the Google Chart API or can alternative approaches be recommended?
Google's Chart API isn't a graphic calculator. It displays pre-calculated data, not equations. So if you have the results pre-calculated for a series of x-values, then yes, the Chart API can plot it.
(If the number of points is < ~5k, a Google Spreadsheet is probably your fastest route to try it out.)
If you don't have the results already calculated - if you just have the equations - then your problem's more of a maths question than a Chart API question. (But again, a spreadsheet might be a fast way to get going.)
Is there a way to display multiple charts on the same image using Google Charts api?
To elaborate:
I have one data series which I want to display as bar chart.
I have another data set which has nothing to do with the first one (well they are correlated but the values are hundred times bigger).
X-axis is for dates.
I want to have second data set displayed as line chart with Y-axis on the left.
I found something similar in "Compound charts" section but as far as I understand markers are calculated based on already displayed data set - and I want to have them independent.
In other words - is it possible to make image like this:
http://chart.apis.google.com/chart?cht=bvg&chm=D,0033FF,1,0,5,1&chs=200x150&chd=t1:30,10,20|60,40,50&chxt=y
but with the line being independent and their values axis being on the right.
I'm sorry I'm not familiar with the terminology - I'm sure there is a name for what I'm trying to achieve.
Thanks!
Only 2 years behind the curve but just to let you know that I have achieved your objective of displaying 2 datasets (one a bar chart, the other a line chart) against 2 different axis scales.
The devil is in the scaling parameter &chds and explicit axis values using &chxr. Essentially, I defined the explicit scales for the x-axis, y-axis and r-axis. and then instructed the scaling parameter to scale each dataset differently.
So for an r dataset between 0 - 10 and a y dataset between 0-2 I would write;
&chds=0,2,0,10 (y then r defined in my axis parameter, i.e. &chxt=y,r)
...and...
&chxr=0,0,2|1,0,10
Let me know if you need more detail!
I've looked into something similar to this before and have used the google chart API a lot. I'm 90% sure the answer is no. Sry :(
Yep it is possible.
Here is an example of two datasets displayed on the same axes. 1 is a bar chart the other is a line graph....
This line - chd=t1:95,1,1,3,10,3,77|95,52,44,24,11,2,1 - allows for the two datasets.
