Let say we have a google spreadsheet with the following information.
The Name and Email address is gotten from people filling out a google form. The Pin is gotten by doing =(A2&" "&B2). Normally I could drag the first value down to fill out the empty cells, but is there a way that, when a new entry is added to the spreadsheet through the google form, the pin for that entry also get filled out?
use in row 1:
={"Pin"; INDEX(A2:A&" "&B2:B)}
I have a wxListbook that has some items, the following it is just a preview picture:
I want to get all item titles but before that, I want to get all items first then creating a for loop which in turn getting each item's title.
I found a method called GetListView() but it doesn't return array-like.
Is there a method to get all the items of that wxListbook?
wxListbook inherits from wxBookCtrlBase which defines GetPageCount() and GetPageText() methods that you can use to iterate over the pages and retrieve their labels, respectively.
I am using Chart.js 2.5.0 and wondered if anyone could give me some pointers on the following functionality requirement.
I have a bubble chart that for arguments sake contains tweets.
I have a list view next to the chart that display the tweets. Connected to this is the ability to filter, so it will only display tweets with specific string value the user inputs.
What I would like to do is when the user utilities the filter, it only shows the bubbles corresponding to the filtered result. I am passing the pointIndex and the datSetIndex into my table. However, I am really struggling in working out how to update the chart so it hides the bubbles that are not matching the current filter output.
Any suggestions?
This doesnt solve my entire issue as Im using Vue which seems to be causing issues with updating the chart. However if you are using plain chart.js the blow fiddle gives one way to hide specific or all points

I am creating a markers-based Geochart to display the location of schools. I have my data in a Google docs spreadsheet. I'm using 3 columns: lat, long and marker size. Currently, the tooltips display lat and long. Ideally, they would display information about each school instead but removing them would be fine, too. See what I have so far on jsfiddle.
Some of the other Google visualizations seem to allow a trigger:'none' option for tooltip (e.g., Pie Chart). Am I correct that there is no such thing for GeoChart?
It seems there's an experimental feature that allows assigning a tooltip role to a particular data column. I tried to use that to no avail.
I tried finding and hiding the tooltip div but I couldn't figure out how to access any elements in the iframe that contains the map. I'd be perfectly happy with this kind of solution if I could get it to work!
I realize this is not exactly what Geochart seems meant for but I'm using other Geochart region maps on the same page and would like to keep the same aesthetic.
I know this is an old question, but maybe it can still help.
Check out this example:
data.addColumn('number', 'Lat');
data.addColumn('number', 'Long');
data.addColumn('string','tooltip');
data.addColumn('number','Example');
data.addRows([[41.151636,-8.569336,'Portugal',{v:0,f:'test PT'}]]);
data.addRows([[ 39.059575,-98.789062,'USA',{v:1,f:'test US'}]]);
You can now also disable the tooltip adding, which was not previously available:
tooltip.trigger:'none';

I create dinamically a chart for a website. I have a key/value map, I sort the values descending, and then create the url:
http://chart.googleapis.com/chart?
chs=400x200&cht=bhs&chbh=a&chdlp=l&chg=25,0&chma=0,0,0,5&chtt=Chart+test&
chxr=0,0,8,1&chds=0,8&chxt=t,y&
chd=t:8,5,3&
chxl=1:|Label_8|Label_5|Label_3
The values are set by chd=t:8,5,3, and the labels are set by chxl=1:|Label_8|Label_5|Label_3. However, in the chart image the labels are reversed.
I searched the documentation, but I didn't get why it is like this. Is it because I didn't set a value correctly, or is this the desired functionality?
I could reverse the label texts in chxl from code to be displayed how I want. Is this the right way?
i haven't found any mention about it either, but just made a try with -1 and it works. So use it like:
chxl=-1:|Label_8|Label_5|Label_3
