I have bar charts with 3 bars for fatal, serious and slight injuries at an accident location. A few of the Locations show no chart when zoomed out. At first I thought my data was incorrect but if you zoom in on that point the chart appears. For eg I have a Location with 1 Fatal so it showed 1 small red bar chart. Fairly close by there was another Location with 2 fatal, 1 serious and 1 slight. No chart is shown until I zoom in, then I see the red, orange and yellow bars. It is just a few random Locations that behave like this with varying injuries. Does anyone know how I can correct this?
