Hi, I recently created a scatter plot, using the visualization api, and I was getting the incorrect row index when selecting a plot from the graph. After investigating this, I realised that the incorrect index value was due to missing (Null) data values. For example, using the following data, it can be seen that there is a value missing for point 1:
data.setValue( 0, 0, -1.22145811867 ); data.setValue( 0, 1, -0.844807630252 ); data.setValue( 1, 0, -0.114704030661 ); data.setValue( 2, 0, -1.28362947541 ); data.setValue( 2, 1, -0.177596736358 ); The scatter plot (and other graph types) deal with this by simply not plotting anything for point 1. However, if I now use the getSelection () method on the select event of the scatterplot and click on point 2, the row index returned is '1', whereas I would expect '2'. I assume, this means that point 1 must not be in the data table created by the visualization. This was something I was not expecting, I have rectified the problem by filtering out incomplete values within my own code before constructing the visualization. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
