Shi JieYou have pointed out one feature of the pie chart, that is, to present information in %. In other words, we can get some meaningful information when trying to interpret the the slices in the chart. E.g. we know the same number of cities are experiences sunshine and shower in the same day. Of course, we will not draw out 'exact figures' from the chart.Now, try to look at the 3 other graphs. Are we able to draw out information that make sense from them? or some actually would give STRANGE answers?Try again.
