Hi,
I have datastore Kind name as Energy with fields as Power and
RecValue.
My db Model is
Class Energy(db.model)
Power=db.IntegerProperty
RecValue=db.IntegerProperty
I have bulkloader.py to read the data from CSV to stored in Energy
Datastore.
I want another index.py file to read the data from Energy datastore
and show as line graph using visualization in Google App Engine.
I am trying with gviz_api. gviz_api is work in normal python file but
not work in Google App engine. Import Module error occured when I am
using gviz_api.
I follow the sample in Google Visualization api with Data Request. The
code is
function drawVisualization() {
var query = new google.visualization.Query(
'http://spreadsheets.google.com/tq?key=pCQbetd-
CptGXxxQIG7VFIQ&range=B1:D11&pub=1');
// Send the query with a callback function.
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' +
response.getDetailedMessage());
return;
}
var data = response.getDataTable();
visualization = new google.visualization.IntensityMap
(document.getElementById('visualization'));
visualization.draw(data, null);
}
I want complete sample source code for datastore based data source
request using visualization in Google App Engine.
