Re: [visualization-api] DateRangeFilter change trigger draw on chart outside the dashboard

[Giulio Mastrosanti]

it is not the dashboard to have an animation, is the chart outside of the 
dashboard that, if has an animation, gets affected from changes in the 
dashboard, as you can see here:

Re: [visualization-api] DateRangeFilter change trigger draw on chart outside the dashboard

[Giulio Mastrosanti]

Hi Daniel,

I was setting up a demo page for you,
but I have noticed that the second chart had an 

  animation: {"startup": true,"duration": 500},

in the options
since I have already got problems with animation with the the dashboard, I 
have removed the option and now it seems OK, so it seems that the second 
chart is not redrawn, but has simply its animation start again for some 
reason.
no problem for me, data is important and I can live without animations:)

if it is of some use for you, I'll let for a while my little demo here:

http://www.solomac.it/prototipo/statistiche3.php

but for me the problem is closed.

thanks for your help today and yesterday

Giulio

[visualization-api] DateRangeFilter change trigger draw on chart outside the dashboard

[Giulio Mastrosanti]

HI,

I have on one page a dashboard with an AreaChart and a DateRangeFilter to 
filter it,
but there's also another AreaChart independent from the dashboard.

I've noticed that, changing the DateRangeFilter, also the external 
AreaChart is redrawn.

is this a normal behaviour  and how can it be avoided?

thanks,

iulio

[visualization-api] Re: How to call data to be used for the graph from a file on the FTP server

[Giulio Mastrosanti]

well,
I think you should read the data on the server side using AJAX, just as I 
do for interrogating a database.
from my web page I do an AJAX call to a php file on the server, that 
performs a query on the database and then sends back the data in JSON 
format, that then is used by javascript to populate the DataTable and then 
draw the chart.
In your case, the php ( or whatever ) on the server side should read  the 
file, parse it some way depending on file format ( tab delimited,etc ) and 
return a JSON object

for the real time I think you could set a timer, and at a given interval 
populate again the DataTable a draw again the chart

hope this helps,
Giulio

[visualization-api] Re: Google Charts don't render in outlook

Hi,
I'm a beginner in this forum and as I beginner I'll answer you:
I'm quite sure that's simply because mail client will not execute the 
javascript necessary to draw the chart

Re: [visualization-api] dot as grouping separator on vaxis data

[Giulio Mastrosanti]

Daniel,

thank you so MUCH!

I wasn't aware of the possibility os settings the language on load,
it solved my symbol problem, and I think will help me on much more ways.

thanks again!



the grouping symbol is automatically determined based on the locale, so if

Re: [visualization-api] dot as grouping separator on vaxis data

[Giulio Mastrosanti]

addendum:

I'm also trying if it could help specifying a format using ICU standard,
and I did try

'vAxis': { 'format': '#.###' },

but that shows me the values without any grouping symbol

and a pattern like:

'vAxis': { 'format': '#.###,#' },

results in chart not displaying and a 'Malformed pattern' error

Re: [visualization-api] dot as grouping separator on vaxis data

[Giulio Mastrosanti]

Hi Daniel,
thank you for your answer,
but unfortunately I still see commas as group separator for the numbers on 
the vAxis
while I was able to correctly format the generated data for the hAxis, 
that's a date
here it is my code for chart creation, including your suggestion ( the 
AreaChart is created using a ChartWrapper, because it is part of a 
Dashboard ) :

var AreaChartasc = new google.visualization.ChartWrapper({
  'chartType': 'AreaChart',
  'containerId': 'chart_Ascolti',
  'options': {
  'title': 'titolo',
  'vAxis': { 
'gridlines': { 'count': -1 }, // variable number of gridlines, 
enables formatOptions as well.
'formatOptions': { 'groupingSymbol': '.' },
   },
  'hAxis': { 'format': 'dd/MM' },
  'crosshair': { 'trigger': 'both' },
  'view': {'columns': [0, 1, 2, 3]}
  }
});

thanks again for your effort,

Giulio

Re: [visualization-api] dot as grouping separator on vaxis data

[Giulio Mastrosanti]

Hi Daniel,
thanks so much for you answer,
but I did try it without success.

I'm able to format as I want the hAxis generated data, that's in date 
format, but trying to apply your suggestion does not seem to solve the 
problem,
here a little snippet of code ( the AreaChart id generated using a 
chartWrapper, because it is part of Dashboard ) :

var AreaChartasc = new google.visualization.ChartWrapper({
  'chartType': 'AreaChart',
  'containerId': 'chart_Ascolti',
  'options': {
  'title': 'titolo',
  'vAxis': { 
'gridlines': { 'count': -1 }, // variable number of gridlines, 
enables formatOptions as well.
'formatOptions': { 'groupingSymbol': '.' },
   },
  'hAxis': { 'format': 'dd/MM' },
  'crosshair': { 'trigger': 'both' },
  'view': {'columns': [0, 1, 2, 3]}
  }
});

thsnaks again for your effort,

[visualization-api] dot as grouping separator on vaxis data

[Giulio Mastrosanti]

HI,

cant find a way to format the vaxis numbers on a AreaChart created by 
a ChartWrapper linked to a Dashboard

I have managed to format correctly the data loaded using a formatter:

formatter = new google.visualization.NumberFormat({fractionDigits: 0, 
groupingSymbol:'.'});

and applying it to the data column, but the values that appear as a 
reference on the vertical axis are using the comma as grouping separator

thank you,

Giulio
