This worksheet explains how to create a bar chart that shows both<\/strong> the counts and the percentage values on a single chart:<\/p>\n Note<\/strong>: To show\u00a0either counts or<\/strong> percents on a bar chart, use the preconfigured chart styles supplied with Snap: Bar Counts Labelled<\/strong> or Bar percent labelled<\/strong>.<\/p>\n <\/a><\/p>\n Bar charts are different from tables because you can only display one value for each bar (the height of the bar on the scale).<\/p>\n You can represent counts and percentage values together in a table. For a bar chart, the height of the bar must be either the counts or the percentage. If you want to display both the counts and the percentage value, you need to pass in the counts and use the Chart Designer<\/strong> to calculate the percentages from the counts.<\/p>\n <\/a><\/p>\n The examples below use the Bar 2D<\/strong> style to display an item in the Analysis <\/strong>field.<\/p>\n If you enter a term in the Analysis <\/strong>field, the Snap bar chart styles identify the separate items by colour, and use a key to tell you which bar is associated with which question or question code.<\/p>\n You can enter analysis terms in both the Analysis <\/strong>and the Break <\/strong>fields (as for a cross-tabulation) and see the results displayed as a bar chart. If you want your chart to give the exact values for each bar, you can display them on the chart.<\/p>\n Bar chart of counts using the Bar 2D Transposed Labelled<\/strong> style. The term is in the Analysis <\/strong>field and the Transpose <\/strong>box is checked. When you display a percentage, you need to know what it is a percentage of. The base percents shown in the table are calculated as the percentage of all the respondents that gave that response.<\/p>\n If you are charting a single-response question, the total number of responses is probably the same as the number of respondents. If you are charting a multi-response question, there will be more responses than respondents.<\/p>\n The Chart Designer <\/strong>can’t work out how many respondents there are from the number of responses, so it can’t calculate the percentages automatically. You must tell it. <\/a><\/p>\n <\/a><\/p>\n The percentage values displayed on the chart are now correct.<\/li>\n <\/a><\/p>\n You can stop displaying the y-axis by clearing the Show<\/strong> box change the number of grid divisions to a factor of 205 (e.g. 5), so that no decimal places are needed. You do this by setting the value in the Major <\/strong>box under Divisions<\/strong>.<\/p>\n Change the display of the labels so they do not show decimal places.<\/li>\n<\/ol>\n You can save the chart style that you have just created by right-clicking the chart and selecting Save Style…<\/strong> from the context menu.<\/p>\n<\/div>\n <\/a><\/p>\n This worksheet has explained why you cannot use a generic style to display both counts and correct percentages on a bar chart. It has also explained some of the conventions used in the Snap bar chart styles.<\/p>\n To find out more about how the Chart Designer works, see the section Charts in Detail<\/strong> in the user manual or the online help.

\nIf you enter a term in the Break <\/strong>field, the Snap bar chart styles identify the separate item by labelling the X-axis below the bars. (This also happens if you enter the term in the Analysis field and check Transpose<\/strong>.)
