A search of the forums reveals others who have grappled with null values in charts with varied success, but none seem to address the issue I am facing.
I have data with zeroes and null data. Zeroes mean a definite zero values, where as null means 'no data available'. I'm looking for a way to represent this on the chart. Obviously a zero should be a bar with zero height, but I'd like some kind of signifier of null data, so that those viewing the chart can tell the difference between a zero value and missing data ranges. One thought I had thought of was to translate the null into a negative number and somehow get the chart to refuse to display data going down, but somehow else identify these ranges as being null. Rather vague I agree. It seems strange that I should be the first to tackle this issue, so if anyone has some ideas, I'd be very appreciative. Regards Andy nb. Just putting null data in my charts seems to be an issue for me. When I place 'null' , or '_', which I've seen others use to represent NULL, I occasionally get the 'data must be of the same type' error. Changing nothing else other than whatever my null identifier is to a '0' or empty (,,) fixes the issue- is there one definite symbol to use for NULL? -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
