A random check on the case you provided shows that it takes some amount of time both to load the data (receiving the query response) and to draw the combochart.
My recommendation for the former is to cache the dataTable locally on the client if you know the frequency of change of the underlying sheet data (for example, depending on the browsers you have to support, you might be able to use html5 localStorage to cache the DataTable on the client). For the latter, the graph seems dense enough that you could do some subsampling on the client (like picking one datapoint every five, or something more complex depending on the pattern your data follows) to reduce the number of datapoints without affecting the data quality (at least at the 0x zoom level). /R. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
