Trying to develop a chart that is very similar to - google finance chart <http://www.google.com/finance?q=INDEXDJX%3A.DJI%2CINDEXSP%3A.INX%2CINDEXNASDAQ%3A.IXIC&ei=aXskVPjFL8f1qAHT3IGoCg> .
The chart in the above link allows selecting multiple indexes using the checkbox. Whenever we select, multiple checkbox - it switches to percentage. But while seeing a single index, it shows number. The percentage also depends on the time range. If you change the time slider at the bottom of the chart, it considers - 0% as the baseline from the time the chart started. How do you take care of the number and percentage swapping and calculate percentage change so fast? I am developing a similar chart and started with Google's Annotated TimeLine chart. Link to chart <https://developers.google.com/chart/interactive/docs/gallery/annotationchart?hl=ja#Methods> . Any help would be appreciated. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
