On a line chart in CR9, I have to plot individual values over various time periods that are not known until the chart runs. I get the data plotted but all points are spaced equally rather than to scale. In other words, the total time for the graph might 18 hours with one point plotted at 1 hour, the next 2 hours later, the next 20 minutes later. But they come out the same distance apart, giving no sense of proportion to the total period. Can you control such spacing along this axis? Also, can regular grid lines (i.e., for each hour) be presented regardless of whether there is data for that time, and if you don't know ahead of time how many there should be? Thanks.
