Click on the chart's icon to select it.
Look at the Table, which will now show the rows and columns providing data to the chart. At the top left, you'll see a small black square containing three white bars. Click on this square to toggle the orientation of the bars (and the orientation of the series on the table) between vertical and horizontal.
As you can see from the example, each series is assigned a different colour. In your example above, the 'series' was the temperature. In the example here, the 'series' is the type of rubber band.
If your daughter's hypothesis is that chilled rubber bands can be stretched less than warmed rubber bands before breaking, then your example represents the results of testing that hypothesis better than mine. Each group on your graph shows the result for sample of the same type of band stretched at different temperatures. If her hypothesis is supported, the general pattern in each group would show lengthening bars from left to right (as is shown for types 1, 2, 3 and 5).
An even more effective representation of the results might be a horizontal bar chart, such as Cart 2 below. Same data selection as in your example, but with the bars running left to right.
Best wishes for success in the Science Fair.
