Selecting data ranges
In the example in Figure 40 we selected a contiguous data range by highlighting it and then proceeding to insert a chart. To plot any non-contiguous columns of data we can select the data by selecting the first data series and then selecting the next series while holding down the Ctrl key.
You can also type in the columns. The columns must be separated by a semi-colon. Thus if we wanted to Chart B3: B11 against G3:G11 we can write the selection range as B3:B11;G3:G11.
The two data series you are selecting must be in separate columns or rows. Otherwise Calc will assume that you are adding to the same data series. This last, however, can be handy if you are doing a column or bar chart but only want to chart some of the data. For example we would do this if we only wanted to compare January with June.
