Defining coordinates for line charts

The logical graph coordinates (X- and Y-axis) are used to adjust the input data to the physical dimensions of the chart on the PageOUT sheet, so that the line graph is kept within the chart.

Make sure that the intervals you set for the X- and Y-axis cover the interval between the lowest and highest values in the input data. Also make sure that the interval is not too large. The following examples illustrate how you can set the interval for the X- and Y-axes:

•	If the input data ranges from 0 to 1000 in the X-dimension, and from -50 to 50 in the Y-dimension, set the interval for the X-axis between 0 and 1100, and for the Y-axis between -60 and 60.

•	If the input data ranges from 0 to 100 in the X-dimension, and from 0.2 to 0.5 in the Y-dimension, set the interval for the X-axis between 0 and 110, and for the Y-axis between 0.1 and 0.6.

To define logical graph coordinates - basic mode

In basic mode, you define logical graph coordinates along the Y-axis. The logical graph coordinates along the X-axis span from 0 to 100 and cannot be changed.

1	In the Chart Properties dialog box, enter the largest y-value in Max value.

2	Enter the lowest y-value in Min value.

To define logical graph coordinates - advanced mode

In advanced mode, you define logical graph coordinates both along the Y- and X-axes.

1	In the Chart Properties dialog box, select Advanced options.

2	Enter the largest Y-value in Y high.

3	Enter the lowest Y-value in Y low.

4	Enter the largest X-value in X high.

5	Enter the lowest X-value in X low.
