I have a graph (columns) with numbers of some items by type. Thus only integer values on Y axis make sense: there is one or two … or seven &c. items of the respective type. However—since the maximum number is small, under ten—Y axis shows values 0.5, 1, 1.5, 2, 2.5 and so on. That looks ridiculous, I need only 1, 2, 3… sequence.
In general, you can edit many things in the presentation of graphs/charts. First double-click on an empty area in the chart to put it into Edit mode. Then click on one of the numbers along the axis that you want to change. Then right-click on the same place to get the editing dialog box. Choose Format Axis to get the editing menu. Click on the Scale tab. Uncheck all of the Automatic selections and fill in your own choices for the axis scale and graduations. Click OK when you are happy with the results. That should do it.
Thank you, that indeed did it.
